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.
Med Pay and bodily injury insurance are two other types of coverage that usually follow the person, not the car. Med Pay coverage pays for any injuries that an insured or his passengers may incur in an accident, regardless of who is at fault. Such coverage usually follows the driver. It is based on people, not the vehicle. In fact, such coverage sometimes covers the insured when he is walking or biking. This coverage also usually follows the driver when he rents a car, because the rental vehicle is a substitute for the insured’s own vehicle. However, Med Pay coverage sometimes follows the car. If the passengers in a vehicle don’t have coverage of their own, Med Pay and PIP coverage can extend to their injuries.
Collision coverage has a deductible, which is the amount you pay before your coverage helps pay for your claim. You can typically choose the amount of your deductible when you buy coverage. So, if you choose a $1,000 deductible and your car is later damaged in a covered accident, you'd have to pay $1,000 toward repair costs. Your collision coverage would help pay the rest, up to your coverage limit.
