What happens if you hit a rental car?

Yesterday I rear-ended somebody's rental car. My car has no damage, but his bumper was slightly messed up. Is this something my insurance company will cover?

The claims process after hitting a rental vehicle would be the same as hitting a vehicle owned by another person. You should contact your insurance provider and notify them of the incident. Make sure you provide pictures of the accident scene and any other details or documentation you have from the accident. At that point, your insurance company should be handling the rest from there.
