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).
In the United States, a Department of Motor Vehicles (DMV) is a state-level government agency that administers vehicle registration and driver licensing. Similar departments exist in Canada under different names. The name "DMV" is not used in every state or area, nor are the traditional DMV functions handled by a single agency in every state, but the generic term is widely understood, particularly in the context of driver's license issuance and renewal.
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 to operate large, heavy, or placarded hazardous material vehicles in commerce.
In the United States, vehicle registration plates, known as license plates, are issued by a department of motor vehicles, an agency of the state or territorial government, or in the case of the District of Columbia, the district government. Some Native American tribes also issue plates. The U.S. federal government issues plates only for its own vehicle fleet and for vehicles owned by foreign diplomats. Until the 1980s, diplomatic plates were issued by the state in which the consulate or embassy was located.
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.
Driver's education, driver education, driving education, driver's ed, or driving tuition or driving lessons is a formal class or program that prepares a new driver to obtain a learner's permit or driver's license. The formal class program may also prepare existing license holders for an overseas license conversion or medical assessment driving test or refresher course. It may take place in a classroom, in a vehicle, online, or a combination of the above. Topics of instruction include traffic code or laws and vehicle operation. Typically, instruction will warn of dangerous conditions in driving such as road conditions, driver impairments, and hazardous weather. Instructional videos may also be shown, demonstrating proper driving strategies and the consequences for not observing the rules.
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.
School bus stop laws are laws dictating what a motorist must do in the vicinity of a bus stop being used by a school bus or other bus, coach or minibus providing school transport.
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 offences 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.
Traffic school is the generic common term for remedial courses in Road-traffic safety and safe driving practices. In the United States, these are offered as part of pre-trial diversion programs to Moving violation offenders by traffic courts, in the interest of improving general safety. To offset the oppression suggested by the compulsory nature of traffic school, some businesses present themselves as a "comedy traffic school" where they attempt to have instructors who are, to some degree, entertaining.
The New Jersey Motor Vehicle Commission is a governmental agency of the U.S. state of New Jersey. The equivalent of the department of motor vehicles in other states, it is responsible for titling, registering and inspecting automobiles, and issuing driver's licenses.
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 California Department of Motor Vehicles (DMV) is the state agency that registers motor vehicles and boats and issues driver licenses in the U.S. state of California. It regulates new car dealers, commercial cargo carriers, private driving schools, and private traffic schools. The DMV works with the superior courts of California to promptly record convictions against driver licenses and subsequently suspends or revokes licenses when a driver accumulates excessive convictions. It issues California license plates and driver's licenses. The DMV also issues identification cards to people who request one.
Commercial driver's license training is a specialized instructional program or course designed to prepare a student to obtain a commercial driver's license (CDL), which is required for a career as a truck driver in the United States. During training, students are taught the necessary knowledge and skills to pass a series of tests to obtain their CDL. Such a program generally begins with classroom instruction geared towards passing the written exams for a CDL permit, a learner's permit that allows a student to practice driving skills on public roads with a CDL licensed driver or instructor. Students graduate from CDL training upon receiving their CDLs and proving that they can comfortably and safely drive and maneuver a truck. Most CDL training schools train drivers for a class A CDL, which allows the holder to drive a tractor trailer weighing over 26,000 pounds.
In the United States, driver's licenses are issued by each individual state, territory, and the District of Columbia rather than by the federal government due to federalism. Drivers are normally required to obtain a license from their state of residence and all states recognize each other's licenses for non-resident age requirements. There are also licenses for motorcycle use. Generally, a minimum age of 16 is required to obtain a drivers/M1 license. A state may also suspend an individual's driving privilege within its borders for traffic violations. Many states share a common system of license classes, with some exceptions, e.g. commercial license classes are standardized by federal regulation at 49 CFR 383. Many driving permits and ID cards display small digits next to each data field. This is required by the American Association of Motor Vehicle Administrators’ design standard and has been adopted by many US states. According to the United States Department of Transportation, as of 2018, there are approximately 227 million licensed drivers in the United States.
A driver's manual is a book created by the DMV of a corresponding state in order to give information to people about the state's driving laws. This can include information such as how to get a license, license renewal, road laws, driving restrictions, etc. "In the U.S. there is no central organization that is responsible for the creation of Driver's Manuals.". As a result, there is no set of rules for the states to create the manuals, so all driver's manuals vary by state. However, every state does still follow general guidelines when creating the manuals.
A driver's licence 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.
