An automobile is a vehicle that moves on four wheels and is one of our primary methods of transportation. Automobiles are also known as cars or vehicles. Trucks, sport utility vehicles (SUV), and minivans are different types of automobiles, and are sometimes referred to as cars, vehicles, or motor vehicles.

Automobiles are usually powered by an internal combustion engine using gasoline or diesel fuel, or by one or more electric motors, using energy stored in one or more rechargeable batteries.

In Minnesota, automobiles, which include cars, trucks, SUVs, and minivans, are subject to various state statutes and federal laws that govern their operation, registration, safety standards, and environmental impact. All motor vehicles operated on Minnesota roads must be registered with the Minnesota Department of Public Safety's Driver and Vehicle Services (DVS). This involves obtaining a title and license plates, as well as passing any required inspections. Minnesota also enforces safety standards in line with federal guidelines, which include regulations on vehicle manufacturing and equipment. Additionally, the state has laws concerning the emissions from vehicles, which are designed to reduce air pollution. These laws regulate the types of fuels that can be used and may include incentives for using alternative energy sources, such as electric batteries. Drivers must adhere to the Minnesota Vehicle Code, which sets forth the rules of the road, including speed limits, rules for safe driving, and penalties for traffic violations.
