The Hurt Report, officially Motorcycle Accident Cause Factors and Identification of Countermeasures, was a motorcycle safety study conducted in the United States, initiated in 1976 and published in 1981. [1] [2] The report is named after its primary author, Professor Harry Hurt.
Noted motorcycle journalist David L. Hough described the Hurt Report as "the most comprehensive motorcycle safety study of the 20th century." [3]
The study was initiated by the Department of Transportation's National Highway Traffic Safety Administration, which contracted with the University of Southern California Traffic Safety Center — the work was ultimately conducted by USC professor Harry Hurt. [3]
The Hurt Report findings significantly advanced the state of knowledge of the causes of motorcycle accidents, in particular pointing out the widespread problem of car drivers failing to see an approaching motorcycle and precipitating a crash by violating the motorcyclist's right-of-way. The study also provided data clearly showing that helmets significantly reduce deaths and brain injuries without any increased risk of accident involvement or neck injury. The full title of the report was Motorcycle Accident Cause Factors and Identification of Countermeasures, Volume 1: Technical Report.
After retiring from USC in 1998, Hurt established and headed the Head Protection Research Laboratory (HPRL), of Paramount, CA. [3]
Professor Hurt, with a team of investigators (all of whom were motorcyclists themselves) [3] examined motorcycle accident scenes in the City of Los Angeles, day and night, during the twenty-four-month period of 1976–77. They did on-scene investigations of over 900 accidents and studied 3,600 police reports from the area of each accident. Investigators later returned to 505 crash scenes at the same time of day, same day of the week and with the same environmental conditions to measure traffic volumes, photograph passing motorcycles and interview 2,310 riders who stopped to talk with investigators. This allowed the research team to compare accident-involved riders to riders in the same location who were not involved in a crash. [3]
The study took place throughout the City of Los Angeles including urban as well as rural conditions, e.g., incidents of motorcycles striking animals. [3]
Each accident was studied individually with approximately 1,000 data elements, [3] collected for each of the 900 accident scenes, including measuring and photographing vehicle damage, skid marks, scrape marks, people marks, and interviewing survivors. Hundreds of accident-involved riders donated their helmet to the research, which allowed team members to disassemble, measure, photograph and record the accident damage as part of the study.
The Hurt Report summarized accident findings related to motorcycle crashes into a 55-point list. Among the major points: two-thirds of motorcycle-car crashes occurred when the car driver failed to see the approaching motorcycle and violated the rider's right-of-way. The report also provided data showing clearly that helmets significantly reduce the risk of brain injury and death but with no increased risk of crash involvement or neck injury.
When interviewed in 1999, Professor Hurt "confided that he believes the report is still basically valid." [3]
Nonetheless, while the Hurt Report "remains the benchmark of motorcycle crash research" [4] and contained at the time of its publication factual, verifiable information, in clear scientific terms — it has been described as outdated. In the year 2000, editors from the Motorcycle Safety Foundation wrote, in preparing the National Agenda for Motorcycle Safety: [4]
It was apparent that our effectiveness would be limited by a consistent lack of viable, current research in most subjects related to motorcycling safety. Wide-ranging changes in motorcycling and related factors have altered the motorcycling landscape since the Hurt Report so thoroughly that it is impossible to determine if the findings of past studies are still valid.
The National Agenda for Motorcycle Safety study cited a broad list of changes that have occurred that affect the current validity of the Hurt Report, broken into four categories:
Hurt argues that the age of the study does not necessarily invalidate all its findings or even its core findings; rather, it highlights the need for current work to affirm or update the current state of motorcycle safety:
The more time goes by, the less things look different. Riders today have the same sort of accidents as riders in the 1970s, except that today they crash much more expensive bikes.
— Professor Hugh H. ("Harry") Hurt Jr [3]
Between 1997 and 2008, motorcycle rider annual fatalities increased from 2,116 to 5,290 – a 150 percent jump, according to U.S. Department of Transportation's Fatality Analysis Reporting System. In 2008 alone, deaths due to motorcycle crashes rose by an estimated 2.2 percent while all other vehicle classes saw reductions in fatalities.

In David Hough's book Proficient Motorcycling, Dr. Hurt said he had always assumed a new study would be conducted. [6]
The 1999, the European Commission conducted the MAIDS report, comparable in scale to the Hurt Report, following Organisation for Economic Co-operation and Development (OECD) standards, and studying 921 accidents as well as exposure data on an additional 923 cases from five locations in France, Germany, Netherlands, Spain and Italy.
In 2005, Congress passed the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) law (2005-2009) mandating a new motorcycle crash study [5] and budgeted $2.8 million for the study, providing that motorcyclists, manufacturers, and other motorcycle related organizations would match that amount. [7] The AMA committed $100,000 to the study, and continues to raise awareness and raise funds, and the Motorcycle Safety Foundation pledged $2.8 million — with several conditions, including a provision that at least 900 cases would be studied. [8] At the time, the funding was still about $2 million short. [9] The National Transportation Safety Board originally had recommended a scope of 900 to 1,200 case studies. [10]
In 2009, the Federal Highway Administration and Oklahoma State University's Oklahoma Transportation Center began conducting an 'abbreviated' Motorcycle Crash Causation Study with 300 case studies [10] "to help identify common factors – including road configurations, environmental conditions and rider experience" [5] and "how these factors may be affected by countermeasures that, if effectively implemented, will prevent motorcycle crashes or lessen the harm when they occur." [5]
Consistent with its stated provisions, the Motorcycle Safety Foundation withdrew support of the abbreviated study, [10] saying such a study would be "unlikely to either validate the findings of prior studies or establish, to any statistical significant level, any new causative factors. The abbreviated study would be unlikely to accomplish either of these goals because the sample size is expected to be only 300 crashes, compared to the 900 crashes collected and analyzed in the Hurt Study, 921 in the MAID's Study (Europe 2000) and the 1,200 recommended by the National Transportation Safety Board." [11]
Published in 2011, Liz de Rome and colleagues undertook the first comprehensive study into the effectiveness of motorcycle personal protective equipment. In order to establish whether motorcycle personal protective clothing should be considered an effective safety measure, their in-depth motorcycle crash cohort study was conducted over 12 months in Australia. It found that while protective clothing is associated with reduced risk and severity of crash-related injuries, a high proportion of clothing failed under crash conditions. [12]
Moreover, it also found that motorcycle armor is ineffective at reducing fractures. [12] Subsequent research by Bianca Albanese and colleagues (2017) may explain this ineffectiveness: the CE marking standard for motorcycle armour is too low, with inadequate impact absorption to reduce fractures. It was the first study to conclude that: “A reduction in the maximum force limit would improve rider protection and appears feasible.” [13]
Work continues on determining a global standard for collection of worldwide data on motorcycle accidents and safety, which would enable international sharing of research. Such a standard would meet methodology criteria developed globally with the Organisation for Economic Co-operation and Development (OECD) and complying with Principles of Good Laboratory Practices and national as well as international regulations — ultimately to be adopted as a standard by the International Organization for Standardization (ISO). [3]
While the CE marking standard for motorcycle protective clothing has been criticised for regulatory capture by the industry, the EU is supporting the PIONEERS research programme – a comprehensive study into motorcycle protective clothing – via Horizon 2020 funding. [14] The PIONEERS study aims to inform improved CE standards for motorcyclists’ protective equipment.
To improve motorcycle safety many countries mandate the wearing of personal protective equipment such as protective clothing and helmets. Protective clothing may include certain types of jackets, gloves, boots, and pants. Jackets meant for motorcyclists are typically made of leather or specialized man-made fabrics like cordura or Kevlar. These jackets typically include padding on the elbow, spine, and shoulder regions. This was once quite bulky, but modern technology and materials have made it unobtrusive. Gloves are generally made of leather or Kevlar and some include carbon fiber knuckle protection. Boots, especially those for sport riding, include reinforcement and plastic caps on the ankle and toe areas. Pants are usually leather, cordura, or Kevlar. Except for helmets, none of these items are required by law in any state in the USA, or in any part of the UK but are recommended by many of those who ride.
A motorcycle helmet is a type of helmet used by motorcycle riders. Motorcycle helmets contribute to motorcycle safety by protecting the rider's head in the event of an impact. They reduce the risk of head injury by 69% and the risk of death by 42%. Their use is required by law in many countries.
High-visibility clothing, sometimes shortened to hi vis or hi viz, is any clothing worn that is highly luminescent in its natural matt property or a color that is easily discernible from any background. It is most commonly worn on the torso and arm area of the body. Health and safety regulations often require the use of high visibility clothing as it is a form of personal protective equipment. Many colors of high visibility vests are available, with yellow and orange being the most common examples. Colors other than yellow or orange may not provide adequate luminescence for conformity to standards such as ISO 20471.
Motorcycle safety is the study of the risks and dangers of motorcycling, and the approaches to mitigate that risk, focusing on motorcycle design, road design and traffic rules, rider training, and the cultural attitudes of motorcyclists and other road users.
Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. Some of this subject matter is hotly debated: for example, the discussions as to whether bicycle helmets or cyclepaths really improve safety. The merits of obeying the rules of the road including the use of bicycle lighting at night are less controversial.
This is a list of numbers of motorcycle deaths in U.S. by year from 1994 to 2014. United States motorcycle fatalities increased every year for 11 years after reaching a historic low of 2,116 fatalities in 1997, then increased to over 5,000 around 2008 and then plateaued in the 4 to 5 thousands range in the 2010s. In nine years motorcycle deaths more than doubled from the late 1990s to 2008. Despite providing less than 1% of miles driven, they made up 15% of traffic deaths in 2012.
Motorcycling is the act of riding a motorcycle. For some people, motorcycling may be the only affordable form of individual motorized transportation, and small-displacement motorcycles are the most common motor vehicle in the most populous countries, including India, China and Indonesia.
Motorcycle training teaches motorcycle riders the skills for riding on public roads. It is the equivalent of driver's education for car drivers. Training beyond basic qualification and licensing is available to those whose duty includes motorcycle riding, such as police, and additional rider courses are offered for street riding refreshers, sport riding, off-road techniques, and developing competitive skills for the motorcycle racetrack.
The Snell Memorial Foundation is a nonprofit organization created to provide a high quality standard of safety for helmets. Founded in 1957, the foundation is named after William "Pete" Snell, a popular sports car racer who died in 1956 of head injuries he received when the racing helmet he wore failed to protect his head. A group of friends, scientists, physicians, and others joined together to create a group that would promote research and education as well as test and develop standards to improve the effectiveness of helmets.
Transportation safety in the United States encompasses safety of transportation in the United States, including automobile crashes, airplane crashes, rail crashes, and other mass transit incidents, although the most fatalities are generated by road incidents yearly killing from 32,479 to nearly 38,680 (+19%) in the last decade. The number of deaths per passenger-mile on commercial airlines in the United States between 2000 and 2010 was about 0.2 deaths per 10 billion passenger-miles. For driving, the rate was 150 per 10 billion vehicle-miles: 750 times higher per mile than for flying in a commercial airplane.
Traffic collision reconstruction is the process of investigating, analyzing, and drawing conclusions about the causes and events during a vehicle collision. Reconstructionists conduct collision analysis and reconstruction to identify the cause of a collision and contributing factors including the role of the driver(s), vehicle(s), roadway and general environment. Physics and engineering principles are the basis for these analyses and may involved the use of software for calculations and simulations. Collision reconstruction is sometimes used as the basis of expert witness testimony at trials. Collision reconstructions are typically performed in cases involving fatalities or personal injury. Results from collision reconstructions are also sometimes used for making roads and highways safer, as well as improving safety aspects of motor vehicle designs. Reconstructions are typically conducted by forensic engineers, specialized units in law enforcement agencies, or private consultants.

Lane splitting is riding a bicycle or motorcycle between lanes or rows of slow moving or stopped traffic moving in the same direction. It is sometimes called whitelining, or stripe-riding. This allows riders to save time, bypassing traffic congestion, and may also be safer than stopping behind stationary vehicles.
Motorcycling advocacy is activism for motorcyclists seeking to establish and protect their rights, and to influence issues of interest to the motorcycling community. This includes lobbying organizations that work to influence laws, and groups or individuals who influence public attitudes.
A traffic collision, also called a motor vehicle collision, car accident or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and property damage as well as financial costs to both society and the individuals involved. Road transport is the most dangerous situation people deal with on a daily basis, but casualty figures from such incidents attract less media attention than other, less frequent types of tragedy.
The MAIDS report is a large-scale, comprehensive study of Powered Two Wheelers accidents carried out across five European countries, using both accident and exposure cases, as was done in the Hurt Report, and following the standards of OECD. Starting in September, 1999, over 2000 variables were coded in each of 921 accidents, and exposure data was collected on an additional 923 cases, collected at five locations in France, Germany, Netherlands, Spain and Italy. The investigation was carried out under the auspices of the Association of European Motorcycle Manufacturers (ACEM) with the support of the European Commission
Hugh Harrison (Harry) Hurt, Jr., was an American researcher on motorcycle safety. He was the author of the 1981 Hurt Report, described as "the most comprehensive motorcycle safety study of the 20th century."
The air bag vest is a personal safety device worn by some motorcyclists and horse riders. Airbag vests initially found popularity among equestrian competitors, and airbags have become mandatory in professional motorcycle racing. In 2018, it became compulsory across all classes within the FIM MotoGP World Championship for riders’ race suits to be fitted with airbag systems.
Alcohol-related traffic crashes are defined by the United States National Highway Traffic Safety Administration (NHTSA) as alcohol-related if either a driver or a non-motorist had a measurable or estimated BAC of 0.01 g/dl or above.
[ Quoting Dr. Harry Hurt ] 'We had no idea that study would last so long. We always assumed someone would commission another bigger study. As it worked out, no one ever came up with a contract. Nobody wants to do any new research projects.'
Even Dr. Harry Hurt, interviewed in 2000 for David L. Hough's fantastic and essential book "Proficient Motorcycling," seemed amazed that a more comprehensive study has never come along to replace it. Finally, in 2005, Congress approved a new motorcycle crash study, budgeting $2.8 million, with the stipulation that manufacturers, organizations, and motorcyclists would need to raise an additional $2.8 million.
It's about time. After 26 years, a major new motorcycle crash study is poised to begin. [ ... ] Even so, it wasn't until 2005 that the federal government decided to fund a new motorcycle crash causation study. A federal transportation reauthorization bill (a.k.a. SAFETEA-LU) included $2.1 million for the research, with the caveat that federal funds be matched from a nongovernmental source. [ ... ] Until last month, the Motorcycle Safety Foundation was averse to helping pay for it, fearing the study would be underfunded and would use statistically insignificant samples of motorcycle crashes. The foundation agreed to throw in $2.8 million, 33% more than federally required, but only after extensive lobbying for more government money, which hasn't come through.
The long-awaited follow-up to the 1981 Hurt Study is short at least $2 million, and it's unclear whether that funding will come through any time soon. Or ever.
