Vehicle insurance (also known as car insurance, motor insurance or auto insurance) is insurance for cars, trucks, motorcycles, and other road vehicles. Its primary use is to provide financial protection against physical damage or bodily injury resulting from traffic collisions and against liability that could also arise there from. Vehicle insurance may additionally offer financial protection against as theft of the vehicle, and against damage to the vehicle sustained from events other than traffic collisions, such as keying and damage sustained by colliding with stationary objects. The specific terms of vehicle insurance vary with legal regulations in each region.
Widespread use of the automobile began after the First World War in urban areas. Cars were relatively fast and dangerous by that stage, yet there was still no compulsory form of car insurance anywhere in the world. This meant that injured victims would seldom get any compensation in an accident, and drivers often faced considerable costs for damage to their car and property.
A compulsory car insurance scheme was first introduced in the United Kingdom with the Road Traffic Act 1930. This ensured that all vehicle owners and drivers had to be insured for their liability for injury or death to third parties whilst their vehicle was being used on a public road. Germany enacted similar legislation in 1939.
In many jurisdictions it is compulsory to have vehicle insurance before using or keeping a motor vehicle on public roads. Most jurisdictions relate insurance to both the car and the driver, however the degree of each varies greatly.
Several jurisdictions have experimented with a "pay-as-you-drive" insurance plan which is paid through a gasoline tax (petrol tax). This would address issues of uninsured motorists and also charge based on the miles (kilometers) driven, which could theoretically increase the efficiency of the insurance, through streamlined collection.
In Australia, Compulsory Third Party (CTP) insurance is a state-based scheme that covers only personal injury liability. Comprehensive and Third Party Property Damage insurance are sold separately.
