Ask the Car Insurance Expert
Drove friends car, got in accident, will my car insurance pay for damage?
I'm not sure how much longer he'll want to be your friend because you've caused him a real problem. The accident will have to go under his auto insurance, not yours, and will be on his claim record. It could possibly result in a rate increase for him.
If there's damage to his car, the least you can do is pay for the repairs or pay his collision deductible.
