Are you responsible for the deductible on the insurance of the car you hit if you do not have insurance?

If you were legally At Fault, you are responsible to pay all damages to other vehicle. Even if you pay the other persons deductible, that insurance co. will come after you for total amount. The person that you gave the money to for their deductible will then have to give some of that back to insurance co., if they find out that deductible was given to him (her) by you.
