Motor Vehicle Law




Motor vehicle law covers all the aspects of registering and titling motor vehicles, and licensing drivers. It also covers highway, driver and vehicle safety laws. The associated laws and regulations are governed by both Federal and individual State laws. The National Highway Traffic Safety Administration (NHTSA) within the U.S. Department of Transportation sets and enforces safety performance standards for motor vehicles and motor vehicle equipment, such as regulating fuel economy standards. NHTSA also conducts local highway safety programs. The Federal Highway Administration, also under the umbrella of the U.S. Department of Transportation, administers federal highway programs in partnership with state and local agencies, to promote highway safety and technological excellence.

Although motor vehicle laws vary from state to state, there are some basic doctrines that are enforced nationwide: most motor vehicles may not be driven legally if they have never been registered with the state of residence’s department of motor vehicles, or if the registration has expired; and in order to operate a motor vehicle, there must be some form of licensing of the driver.

The practice of Motor Vehicle Law includes addressing traffic violations while operating a motor vehicle, such as speeding, careless driving, or driving under a suspended license. These violations are criminal offenses and are categorized as either Petty Offenses, Misdemeanors, or Felonies. DUI/DWI Law is a branch of this area of law.
