Ya definetly determine if the damages are more then the deductible, probably true here... call the insurance company (yours and theres) and explain what happened. Then find a shop apprived by the company who is paying. Take the car there, get it appraised and before they start work someone from the insurance company will come look at it. Then they start work and when its done, you go to the shop, pay your deductible and drive home happily...

Or you could have insurance cut you a check, and you can get things fixed your way...

Good luck!
