It's the vehicle you drive to work or school, haul the kids around in, go shopping in. It's your "regular" vehicle. Some specialized insurance policies, like those for RVs or classic cars, require that you also have a regular-use vehicle to qualify for special rates on classic car insurance or RV insurance.
