Driving is the controlled operation and movement of a vehicle, including cars, motorcycles, trucks, buses, and bicycles. Permission to drive on public highways is granted based on a set of conditions being met and drivers are required to follow the established road and traffic laws in the location they are driving. The word driving, has etymology dating back to the 15th century and has developed as what driving has encompassed has changed from working animals in the 15th to automobiles in the 1800s. Driving skills have also developed since the 15th century with physical, mental and safety skills being required to drive. This evolution of the skills required to drive have been accompanied by the introduction of driving laws which relate to not only the driver but the driveability of a car.
Drunk driving is the act of operating a motor vehicle with the operator's ability to do so impaired as a result of alcohol consumption, or with a blood alcohol level in excess of the legal limit. For drivers 21 years or older, driving with a blood alcohol concentration (BAC) of 0.08% or higher is illegal. For drivers under 21 years old, the legal limit is lower, with state limits ranging from 0.00 to 0.02. Lower BAC limits apply when operating boats, airplanes, or commercial vehicles. Among other names, the criminal offense of drunk driving may be called driving under the influence (DUI), driving while intoxicated or impaired (DWI), operating [a] vehicle under the influence of alcohol (OVI), or operating while impaired (OWI).
Driving under the influence (DUI) is the offense of driving, operating, or being in control of a vehicle while impaired by alcohol or other drugs, to a level that renders the driver incapable of operating a motor vehicle safely. Multiple other terms are used for the offense in various jurisdictions.
Vehicular homicide is a crime that involves the death of a person other than the driver as a result of either criminally negligent or murderous operation of a motor vehicle.
Mothers Against Drunk Driving (MADD) is a non-profit organization in the United States, Canada and Brazil that seeks to stop drunk driving, support those affected by drunk driving, prevent underage drinking, and strive for stricter impaired driving policy, whether that impairment is caused by alcohol or any other drug. The Irving, Texas–based organization was founded on September 5, 1980, in California by Candace Lightner after her 13-year-old daughter, Cari, was killed by a drunk driver. There is at least one MADD office in every state of the United States and at least one in each province of Canada. These offices offer victim services and many resources involving alcohol safety. MADD has claimed that drunk driving has been reduced by half since its founding.
An ignition interlock device or breath alcohol ignition interlock device is a breathalyzer for an individual's vehicle. It requires the driver to blow into a mouthpiece on the device before starting or continuing to operate the vehicle. If the resultant breath-alcohol concentration analyzed result is greater than the programmed blood alcohol concentration, the device prevents the engine from being started. The interlock device is located inside the vehicle, near the driver’s seat, and is directly connected to the engine’s ignition system. It is a form of electronic monitoring.
License suspension or revocation traditionally follows conviction for alcohol-impaired or drunk driving. However, under administrative license suspension (ALS) laws, sometimes called administrative license revocation or administrative per se, licenses are confiscated and automatically suspended independent of criminal proceedings whenever a driver either (1) refuses to submit to chemical testing, or (2) submits to testing with results indicating a blood alcohol content of 0.08% or higher.
A commercial driver's license (CDL) is a driver's license required in the United States to operate large and heavy vehicles or a vehicle of any size that transports hazardous materials or more than 15 passengers.
Graduated driver licensing systems (GDLS) are designed to provide new drivers of motor vehicles with driving experience and skills gradually over time in low-risk environments. There are typically three steps or stages through which new drivers pass. They begin by acquiring a learner's permit, progress to a restricted, probationary or provisional license, followed by receipt of a full driver's license. Graduated drivers' licensing generally restricts nighttime, expressway, and unsupervised driving during initial stages, but lifts these restrictions with time and further testing of the individual, eventually concluding with the individual attaining a full driver's license.
DWI courts are a form of court that exists in some United States legal jurisdictions, that use substance-abuse interventions and treatment with defendants who plead guilty of driving while intoxicated or impaired. DUI courts may focus on repeat offenders and drivers with very high levels of blood alcohol at the time of the offense. As of December 2011, there were approximately 192 designated DUI courts in the United States, and approximately 406 drug courts that also accept DUI offenders.
Many countries have adopted a penalty point or demerit point system under which a person’s driving license is cancelled or suspended based on the number of points accumulated by them over a period of time because of the traffic offenses or infringements committed by them in that period. The demerit points schemes of each jurisdiction varies. These demerit schemes are usually in addition to fines or other penalties which may be imposed for a particular offence or infringement, or after a prescribed number of points have been accumulated.
A random checkpoint is a military and police tactic. In a military context, checkpoints involve the setup of a hasty roadblock by mobile truck- or armored vehicle-mounted infantry to disrupt unauthorized or unwanted movement or military activity and to check for valid identification and search for contraband, fugitives, or weapons that are not permitted in civilian hands. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could circumvent. They are often established in locations where they cannot be observed by approaching traffic until it is too late to withdraw and escape without being observed.
The German laws regulating alcohol use and sale are mostly focused on youth protection. In contrast to many other countries, legislation is relatively lenient and not designed to keep young people away from alcohol, but rather intended to teach them an appropriate approach to alcohol consumption, which is reflected by one of the lowest drinking ages in the world.
86 percent of people in the United States use private automobiles as their primary form of transportation to their workplace.
The U.S. state of Maryland has various policies regarding the production, sale, and use of different classes and kinds of drugs.
The laws of driving under the influence vary between countries. One difference is the acceptable limit of blood alcohol content before a person is charged with a crime.
Drunk driving is the act of driving under the influence of alcohol. A small increase in the blood alcohol content increases the relative risk of a motor vehicle crash.
Alcohol-related crime refers to criminal activities that involve alcohol use as well as violations of regulations covering the sale or use of alcohol; in other words, activities violating the alcohol laws. Underage drinking and drunk driving are the most prevalent alcohol‐specific offenses in the United States and a major problem in many, if not most, countries worldwide. Similarly, arrests for alcohol-related crimes constitute a high proportion of all arrests made by police in the U.S. and elsewhere.
Driving under the influence (DUI) occurs when a person operates a motor vehicle while under the influence of drugs or alcohol, or when the driver has a blood alcohol level of 0.08 or greater. Minors and young adults aged 18–20 can be charged with impaired driving based on blood alcohol levels of 0.01 or higher, and CDL license holders can be charged based upon blood alcohol levels of 0.04 or higher.
Two main questions arise in the law surrounding driving after having ingested cannabis: (1) whether cannabis actually impairs driving ability, and (2) whether the common practice of testing for THC is a reliable means to measure impairment. On the first question, studies are mixed. Several recent, extensive studies–including one conducted by the National Highway Traffic Safety Administration and one conducted by the American Automobile Association (AAA)–show that drivers with detectable THC in their blood are no more likely to cause car crashes than drivers with no amount of THC in their blood. Others show that cannabis can impair certain abilities important to safe driving –but no studies have been able to show that this increases the actual risk of crashing, or that drivers with THC in their blood cause a disproportionate number of crashes. On the second question, the studies that have been conducted so far have consistently found that THC blood levels and degree of impairment are not closely related. No known relationship between blood levels of THC and increased relative crash risk, or THC blood levels and level of driving impairment, has been shown by single-crash or classic-control studies. Thus, even though it is possible that cannabis impairs driving ability to some extent, there are currently no reliable means to test or measure whether a driver was actually impaired.
