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 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.
