Driving is the controlled operation and movement of a land vehicle, including cars, motorcycles, trucks, and buses. 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 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.
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.
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.
A driver's permit, learner's permit, learner's license or provisional license is a restricted license that is given to a person who is learning to drive, but has not yet satisfied the prerequisite to obtain a driver's license. Having a learner's permit for a certain length of time is usually one of the requirements for applying for a full driver's license. To get a learner's permit, one must typically pass a written permit test, take a basic competency test in the vehicle, or both.
Many countries have adopted a penalty point or demerit point system under which a person’s driving license is revoked or suspended based on the number of points they’ve accumulated over a specific period of time, points are given for 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.
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.
Swedish driving licences adhere to a standard set in the European Economic Area. 18 years is the minimum age to obtain a licence for cars.
In the United Kingdom, a driving licence is the official document which authorises its holder to operate motor vehicles on highways and other public roads. It is administered in England, Scotland and Wales by the Driver and Vehicle Licensing Agency (DVLA) and in Northern Ireland by the Driver & Vehicle Agency (DVA). A driving licence is required in England, Scotland, and Wales for any person driving a vehicle on any highway or other "road", as defined in s.192 Road Traffic Act 1988, irrespective of the ownership of the land over which the road passes. Similar requirements apply in Northern Ireland under the Road Traffic Order 1981.
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. Thresholds range from the limit of detection (zero-tolerance) to 0.08%. Some countries have no limits or laws on blood alcohol content.
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.
A driver's license, driving licence, or driving permit is a legal authorization, or the official document confirming such an authorization, for a specific individual to operate one or more types of motorized vehicles—such as motorcycles, cars, trucks, or buses—on a public road. Such licenses are often plastic and the size of a credit card.
A Lebanese driving licence is a driving licence issued by the government of Lebanon. It authorises its holder to operate various types of motor vehicles on highways and some other publicly accessible roads. It is issued by each individual district.
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.
