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 Pennsylvania, automobiles, which include cars, trucks, SUVs, and minivans, are primarily regulated by the Pennsylvania Vehicle Code. This comprehensive set of laws governs various aspects of vehicle operation, registration, safety standards, and emissions. All motor vehicles operating on Pennsylvania roads must be registered with the Pennsylvania Department of Transportation (PennDOT) and display valid license plates. Safety inspections are required annually for most vehicles, and emissions inspections are required for vehicles in certain areas to ensure compliance with environmental standards. Automobiles must be insured with minimum liability coverage as per state requirements. Additionally, Pennsylvania recognizes the use of alternative fuel vehicles, including electric vehicles (EVs), and has regulations in place for their operation and charging infrastructure. Drivers must adhere to traffic laws, and violations can result in fines, points on a driver's license, or other penalties.
