The Federal Bridge Gross Weight Formula, also known as Bridge Formula B or the Federal Bridge Formula, is a mathematical formula in use in the United States by truck drivers and Department of Transportation (DOT) officials to determine the appropriate maximum gross weight for a commercial motor vehicle (CMV) based on axle number and spacing. The formula is part of federal weight and size regulations regarding interstate commercial traffic. The formula is necessary to prevent heavy vehicles from damaging roads and bridges. CMVs are most often tractor-trailers or buses, but the formula is of most interest to truck drivers due to the heavy loads their vehicles often carry.

These rules limit the number of daily and weekly hours spent driving and working, and regulate the minimum amount of time drivers must spend resting between driving shifts. For intrastate commerce, the respective state's regulations apply.

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 parking violation is the act of parking a motor vehicle in a restricted place or for parking in an unauthorized manner. It is against the law virtually everywhere to park a vehicle in the middle of a highway or road; parking on one or both sides of a road, however, is commonly permitted.

Such offenses are usually cited by a police officer or other government official in the form of a traffic ticket.

Peter rehra, ਪੀਟਰ ਰੇਹੜਾ is a homemade vehicle used in rural Punjab. It is made by assembling a diesel engine,(mostly meant for pumping water), removing the pumpset assembly from it, and joining it with a framework made steel angles and wooden planks, and finally completing it all by putting four movable wheels, two are steerable and the two rear ones directly attached to the engine via a primitive gear-assembly. It is, of course, not meant for high-performance, but for sheer-economy, as it is easily able to carry twenty to twenty five grown-up people, but mostly cannot move at more than 25 km/h. There has been instances when police themselves used this to carry a whole Maruti 800

Most seat belt laws in the United States are left to the states and territories. However, the first seat belt law was a federal law, Title 49 of the United States Code, Chapter 301, Motor Safety Standard, which took effect on January 1, 1968, that required all vehicles to be fitted with seat belts in all designated seating positions. This law has since been modified to require three-point seat belts in outboard-seating positions, and finally three-point seat belts in all seating positions. Initially, seat belt use was voluntary. New York was the first state to pass a law which required vehicle occupants to wear seat belts, a law that came into effect on December 1, 1984. New Hampshire is the only state that has no enforceable laws for the wearing of seat belts in a vehicle.

Street-legal, road-legal, or road-going, refers to a vehicle such as a car, motorcycle, or light truck that is equipped and licensed for use on public roads, being therefore roadworthy. This will require specific configurations of lighting, signal lights, and safety equipment. Some specialty vehicles that will not be operated on roads, therefore, do not need all the features of a street-legal vehicle; examples are a vehicle used only off-road that is trailered to its off-road operating area, and a racing car that is used only on closed race tracks and therefore does not need all the features of a street-legal vehicle. As well as motor vehicles, the street-legal distinction applies in some jurisdictions to track bicycles that lack street-legal brakes and lights. Street-legality rules can even affect racing helmets, which possess visual fields too narrow for use on an open road without the risk of missing a fast-moving vehicle.
