The National Hot Rod Association (NHRA) is a drag racing governing body, which sets rules in drag racing and hosts events all over the United States and Canada. With over 40,000 drivers in its rosters, the NHRA claims to be the largest motorsports sanctioning body in the world. [1]

Drag racing type of motor racing in which automobiles or motorcycles compete

Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly 14 mi, with a shorter becoming increasingly popular, as it has become the standard for Top Fuel dragsters and funny cars, where some major bracket races and other sanctioning bodies have adopted it as the standard, while the 18 mi is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.

United States Federal republic in North America

The United States of America (USA), commonly known as the United States or simply America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe. Most of the country is located in central North America between Canada and Mexico. With an estimated population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the most populous city is New York City.

Canada Country in North America

Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Its southern border with the United States, stretching some 8,891 kilometres (5,525 mi), is the world's longest bi-national land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver.


The association was founded by Wally Parks in 1951 in California to provide a governing body to organize and promote the sport of drag racing. NHRA's first Nationals was held in 1955, in Great Bend, Kansas. (Typical for the era, this race was held on a World War II-constructed training air field.) The NHRA Mello Yello Drag Racing Series, the national event series which comprises 24 races each year, is the premier series in drag racing that brings together the best drag racers from across North America and the world. The NHRA U.S. Nationals are now held at Lucas Oil Raceway in Brownsburg, Indiana and are officially called the U.S. Nationals. Winners of national events are awarded a trophy statue in honor of founder Wally Parks. The trophy is commonly referred to by its nickname, a “Wally”.

Wally Parks American editor

Wallace Gordon Parks was an American writer. He was the founder, president, and chairman of the National Hot Rod Association, better known as NHRA. He was instrumental in establishing drag racing as a legitimate amateur and professional motorsport.

California State in the United States

California is a state in the Pacific Region of the United States. With 39.6 million residents across a total area of about 163,696 square miles (423,970 km2), California is the most populous U.S. state and the third-largest by area. The state capital is Sacramento. The Greater Los Angeles Area and the San Francisco Bay Area are the nation's second- and fifth-most populous urban regions, with 18.7 million and 9.7 million residents respectively. Los Angeles is California's most populous city, and the country's second-most populous, after New York City. California also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The City and County of San Francisco is both the country's second-most densely populated major city after New York City and the fifth-most densely populated county, behind only four of the five New York City boroughs.

Great Bend, Kansas City and County seat in Kansas, United States

Great Bend is a city in and the county seat of Barton County, Kansas, United States. It is named for its location at the point where the course of the Arkansas River bends east then southeast. As of the 2010 census, the population of the city was 15,995.

NHRA Championship Drag Racing Series

The NHRA Mello Yello Drag Racing Series is the top division of the NHRA. It consists of four professional classes:

NHRA Mello Yello Drag Racing Series

The NHRA Mello Yello Drag Racing Series is a drag racing series organized by the National Hot Rod Association (NHRA). It is the top competition series of the NHRA, comprising competition in four classes, including Top Fuel Dragster, Funny Car, Pro Stock, and Pro Stock Motorcycle.

Top Fuel

Top Fuel dragsters are the quickest accelerating racing cars in the world and the fastest sanctioned category of drag racing, with the fastest competitors reaching speeds of 335 miles per hour (539 km/h) and finishing the 1,000 foot (305 m) runs in 3.62 seconds.

Dragster (car) specialized competition automobile used in drag racing

A dragster is a specialized competition automobile used in drag racing.

Funny Car type of racing car

Funny Car is a type of drag racing vehicle and a specific racing class in organized drag racing. Funny cars are characterized by having tilt-up fiberglass or carbon fiber automotive bodies over a custom-fabricated chassis, giving them an appearance vaguely approximating manufacturers' showroom models. They also have the engine placed in front of the driver, as opposed to dragsters, which place it behind the driver.


NHRA Sportsman Drag Racing Series

There are more than a dozen Sportsman Classes. The classes contested at NHRA Divisional races include Snowmobile, Motorcycle Classes, Super Street, Super Gas, Stock Eliminator, Super Stock, Competition Eliminator, Super Comp, Top Sportsman, Top Dragster, Top Alcohol Funny Car, and Top Alcohol Dragster. All classes except Snowmobile and some Sportsman motorcycle classes are regularly contested at NHRA national events.

NHRA promotes mainly the Professional classes at national Events, however, the majority of its participants are Sportsman Racers. Sportsman-class racers must be dues-paying members of NHRA before they are allowed to enter and participate in any NHRA event.

Included in these sportsman events are the Lucas Oil Drag Racing Series, the Summit Racing Equipment Racing Series and the NHRA Jr. Drag Racing League.

The NHRA Sportsman Drag Racing Series originally consisted of seven divisions: Northeast, Southeast, North Central, South Central, West Central, Northwest, and Pacific. Starting in 2012, the Top Alcohol Dragster and Top Alcohol Funny Car classes competed in four regions: East, North Central, Central and West. [2]

The NHRA mandates numerous safety devices and procedures in all competition events.

The five point safety harness is required for all vehicles. It holds the driver secure in the seat, and is equipped with a quick release latch which can be released in less than a second should the driver need to leave the car due to fire or explosions.

Fire suits are required for all drivers in the alcohol and nitromethane fuel classes and the faster gasoline classes. These suits are full body coveralls and made with seven layers of Nomex fabric, which makes them resistant to fire. The required suit includes Nomex gloves, foot socks, and head sock.

Racing suit

A racing suit or racing overalls, often referred to as a fire suit due to its fire retardant properties, is clothing such as overalls worn in various forms of auto racing by racing drivers, crew members who work on the vehicles during races, track safety workers or marshals, and in some series commentators at the event.

Nitromethane is an organic compound with the chemical formula CH
. It is the simplest organic nitro compound. It is a polar liquid commonly used as a solvent in a variety of industrial applications such as in extractions, as a reaction medium, and as a cleaning solvent. As an intermediate in organic synthesis, it is used widely in the manufacture of pharmaceuticals, pesticides, explosives, fibers, and coatings. Nitromethane is used as a fuel additive in various motorsports and hobbies, e.g. Top Fuel drag racing and miniature internal combustion engines in radio control, control line and free flight model aircraft.

Nomex Flame-resistant meta-aramid material

Nomex is a flame-resistant meta-aramid material developed in the early 1960s by DuPont and first marketed in 1967.

Another NASCAR transplant, which was brought into use after the death of Fireball Roberts, was the fuel cell. This bladder is placed into the fuel tanks of non-nitromethane fueled vehicles to prevent fuel leaks, and explosions.

Third is the use of the HANS device. This device limits the movement of the head and neck in the event of an impact.

Fourth is the titanium shield that must be placed behind the head of all Dragsters and Funny Cars down to the Alcohol ranks. This is to prevent any debris from entering the cockpit and becoming a missile hazard to the driver after the death of Top Fuel racer Darrell Russell.

Fifth is the on-board fire extinguishing system that are required. These systems are directed onto the engine itself and are activated instantly when the engine catches fire, reducing the chance for the car to completely catch fire and endanger the driver. The driver also has a manual activation control available. This has been in place on all cars since 1983, when an engine explosion and fire came very close to killing then-Funny Car driver Mike Dunn. All enclosed body cars must have a five-inch circular opening which will accept the nozzle of a fire extinguisher triggered by safety personnel. All vehicles must have a clearly marked fuel pump cut-off switch on a rear panel, accessible to safety crews.

Sixth is the roof escape hatch that is in place on all Funny Cars since the founding of the division in the early 1970s. This device allows Funny Car drivers a safe means of exit during an engine fire rather than falling out of the car between the frame and fiberglass body, and possibly running the risk of being run over by the rear tires.

Seventh are the long bars at the rear end of all cars, also known as "wheelie bars". These long struts prevent the car from flipping over during the launch phase.

To prevent debris, oil, fuel, or coolant from falling on the racing surface, "diapers" under the engine (with a supporting platform) are used to retain liquids and broken parts in the event of a catastrophic engine failure. "Oil-downs" result in substantial fines and the loss of previously earned Championship points (for annual awards). Many cars using the centrifugally-activated "slipper" clutch are now using a retention tube to collect the substantial amount of clutch dust that is produced during each race. The afore mentioned recent practices, along with the longstanding requirement for a Kevlar-style retainer blanket over the supercharger, considerably reduce the potential for injury and fire, in addition to assuring a cleaner and safer racing surface, resulting in a dramatic reduction in race delays for track clean-up.

The rear tires of the car, which are called slicks due to the fact that there is no tread on them, are specified with safety considerations in mind. These tires are made from a much harder compound than in previous years so that the tire is resistant to disintegration. This also came about after the death of Russell. The tires are not allowed to be inflated under 7 pounds per square inch (48 kPa) for any race at any time.

All cars capable of attaining 150 miles per hour require braking parachutes. A safety requirement on all Drag cars running 9.99 and quicker in the 1/4 mile is the fireproof engine blanket which surrounds the engine block and contains debris in case of an engine explosion. NHRA rules call for a monetary, points, and time penalty if the car leaks oil during the run. During qualifying, the offending team loses its elapsed time and speed from the run; during a race, the penalty is loss of lane choice unless both teams in the ensuing race committed the violation.

In the wake of Eric Medlen's 2007 death, the roll bars in a Funny Car underwent modifications to further improve safety. They are padded with thick insulation and coated with several layers of Nomex to prevent the padding from catching fire during an engine explosion.

Another facility safety feature is the large sand pit at the end of the track past an area of the track known as the "shutdown area", also known as a "sand trap". This 40-foot-long (12 m) sand pit has been placed to slow or stop a car. In the wake of Scott Kalitta's death at Englishtown, NJ in 2008, the sand traps have been made longer and deeper, going from three feet deep to six feet deep and from 40 feet (12 m) long to 80 feet (24 m) long. Anchors for any arresting netting must be buried underground with no obstructing posts.

Some of the newest safety features deal with the tracks themselves. In the wake of Kalitta's death, there are now heavily padded retaining walls at the end of the sand traps. These walls are able to withstand the impact of a vehicle traveling at well over the usual speed of any division within the NHRA's professional categories. These retaining walls take the place of the old rubber polymer safety nets that were once held up with concrete posts.

Another safety modification was a direct result of Kalitta's death. The NHRA began installing a sensor that constantly checks the car's engine, and should the car backfire at any time during the race, or if the burst panel is blown out by an engine explosion, the fuel pump shuts off and the parachutes are deployed automatically. Although several drivers in the Top Fuel and Funny Car divisions have stated their dislike for the new sensor, they do admit that it should cut down on any fatal crashes similar to Kalitta's. This device was developed by Force, Kenny Bernstein, and Tony Schumacher, along with NHRA racing development, and NHRA track safety. It was implemented at the start of the 2009 season. The sensor is used only in the Funny Car and Top Fuel divisions. Pro Stock doesn't use nitromethane or superchargers in their engines and this presents a much reduced risk of the massive explosions that can be seen in the nitromethane-fueled cars—and often at their peak speeds.

Prior to the late 1980s, fans could station themselves up to the guardrails so they could be closer to the action. However, in the wake of several rather dramatic accidents on track, where spectators have been injured or killed, fans are no longer allowed within 75 feet (23 m) of the guardrail.

One of the newest safety requirements came after a near fatal crash at Texas Motorplex in Ennis, Texas, when John Force's car experienced a severe case of tire shake which, coupled with the release of his parachutes, ripped his car cleanly in two directly behind the engine. This frame failure exposed him to severe injury with no body or frame in front of his feet, as the severely damaged vehicle ground to a halt. The rules now prevent the use of hardened chrome moly tubing in the framework construction of any Top Fuel or Funny Car.

The track length for nitromethane-powered vehicles (funny cars and fuel dragsters) has been reduced to 1,000 feet (305 meters), to reduce the likelihood and severity of blower and engine explosions and fires at or above 200 miles per hour. All other classes continue to race a full 1320-foot quarter mile (402 meters) which has been the original distance established by the NHRA in the 1950s.

The 2010 season brought a new safety device to Top Fuel classes. Should the driver be rendered unable to perform the normal shutdown sequence at the conclusion of a run, a pair of redundant transmitters, placed 400 feet (120 m) and 600 feet (180 m) past the finish line, will signal an on-board receiver to automatically shut off ignition power and fuel to the engine and deploy the parachutes. The transmitters are designed and placed so as to avoid inadvertent triggering of the automated shutoffs. [8] These transmitters and the receivers that are placed on all cars were designed by NHRA's Track Safety Committee and constructed by Electrimotion, [9] and are a direct result of Kalitta's death.

Safety Safari

Within the safety requirements, there is also a full crew of safety personnel, called the Safety Safari, whose job is to attend to any fires, clean up the track of debris after an accident on the track, and attend to the drivers prior to the arrival of any medical personnel. The Safety Safari has been in place since the late 1960s, after a rash of on track accidents caused several promising drivers to retire early. Since that time the chance of fatal injuries has been decreased but not eliminated. There is also a full staff of EMTs on hand at any event on the schedule at any given time. These EMTs are usually from the city or county the track is located in, and are compensated by the NHRA for their time and efforts. Aeromedical services are also on hand at the track for airlifting severely injured persons to local hospitals or trauma centers if necessary.[ citation needed ]

The original 'Drag Safari' began their tour across America in 1954. Included were four original members: Bud Coons, Bud Evans, Eric Rickman and Chic Cannon.


Although there are several safety procedures in place to prevent fatal accidents, no amount of safety can completely prevent fatalities on the track.

Don Garlits American drag racing driver

Donald Glenn "Don" Garlits is an American race car driver and automotive engineer. He is considered the father of drag racing. He is known as "Big Daddy" to drag racing fans around the world. Always a pioneer in the field of drag racing, he perfected the rear-engine Top Fuel dragster, an innovation motivated by the loss of part of his foot in a dragster accident. This design was notably safer since it put most of the fuel processing and rotating parts of the dragster behind the driver. The driver was placed in front of nearly all the mechanical components, thus protecting the driver and allowing him to activate a variety of safety equipment in the event of catastrophic mechanical failure or a fire. Garlits was an early promoter of the full-body, fire-resistant Nomex driving suit, complete with socks, gloves, and balaclava.

Shirley Muldowney American Drag Racing Driver

Shirley Muldowney, also known professionally as "Cha Cha" and the "First Lady of Drag Racing", is an American auto racer. She was the first woman to receive a license from the National Hot Rod Association (NHRA) to drive a Top Fuel dragster. She won the NHRA Top Fuel championship in 1977, 1980, and 1982, becoming the first person to win two and three Top Fuel titles. She won a total of 18 NHRA national events.

Darrell J. Russell was an American National Hot Rod Association (NHRA) drag racer. He was the 2001 NHRA Rookie Of The Year. At the time, he was the third driver to win in his Professional class debut.

Junior Dragster Junior Dragster

The Junior Dragster is a scaled-down version of the top fuel dragster. Also known as the Jr dragster, it reaches speeds of up to 85 mph. The cars were developed in New Zealand in 1988, with classes developed by the New Zealand Hot Rod Association. The National Hot Rod Association in the USA began sanctioning the class in 1991, with the JDRL. The JDRL is a division of the NHRA, which consists of two different dragster classes, traditional Jr. Dragster having a wheelbase between 90-150 inches and a single-cylinder, five brake horsepower Briggs & Stratton engine, and the larger Jr. Comp dragster being 150-190 inches in wheelbase and using a motorcycle or personal watercraft engine. Junior drag racers may choose to participate in programs run by the NHRA, IHRA, or at an unsanctioned facility. Drivers may be male or female and must be at least five years of age to test, and six years to compete, and be no older than 20 years on December 31 of the competition year.

Top Alcohol

Top Alcohol refers to two different classes in professional drag racing: Top Alcohol Dragster and the Top Alcohol Funny Car. Commonly known as "alky" cars, both are akin in design to the premier Top Fuel classes, but less powerful. In Top Alcohol Dragster, the cars used supercharged ("blown") engines, burning alcohol (methanol). Top Alcohol Funny Cars look similar to Fuel Funny Cars, with about half the power of a Top Fuel car. In this class only alcohol cars with three-speed transmissions are allowed.

Kenny Bernstein drag racer, auto racing team owner

Kenny Bernstein is an American drag racer and former NASCAR and IndyCar team owner. He is nicknamed the "Bud King" for his success in the Budweiser King funny car and dragster. He has also been nicknamed "The King of Speed," because he was the first driver to break 300 miles per hour in the standing-start quarter mile. Bernstein owned King Racing, which he drove for in the NHRA and fielded various cars in other racing series such as IndyCar and NASCAR. Bernstein retired from full-time competition in 2002 and moved his son Brandon into the Bud King Top Fuel dragster, but returned to finish the season in place of his son after Brandon suffered a severe injury. With the exception of a brief return to Funny Car in 2006, Bernstein did not return to the car and instead continued to run his team until the end of the 2011 season when he left drag racing altogether.
