Drive Other Car insurance is similar to an Individual Named Insured Endorsement. If you need to borrow, test drive, rent, or lease a vehicle, Drive Other Car insurance will extend the coverages you’ve purchased for your commercial auto insurance policy - like Liability insurance, Physical Damage insurance, Medical Payments, and Uninsured Motorist Insurance, to a non-owned car.
When the policy of the vehicle owner and the policy of the permissive user have different limits, the matter becomes even more complicated. If the damages caused by the permissive user’s negligence exceed the owner’s liability limits, the policy of the permissive user might be tapped as secondary coverage, but usually only where the permissive user’s liability limits are higher than the owner’s liability limits.
Collision insurance is a coverage that helps pay to repair or replace your car if it's damaged in an accident with another vehicle or object, such as a fence or a tree. If you're leasing or financing your car, collision coverage is typically required by the lender. If your car is paid off, collision is an optional coverage on your car insurance policy.
