Comprehensive car insurance is a type of coverage that protects you against a wide range of risks, such as theft, vandalism, and damage caused by natural disasters. However, it does not necessarily mean that you can drive any car without any restrictions. Most comprehensive car insurance policies only cover the specific vehicle that is listed on the policy. If you want to drive another car that is not insured under your policy, you may need to add it as an additional vehicle or obtain a separate policy for that specific car.
