If someone is at fault for an accident and the other driver makes a claim on the at-fault driver's liability policy, no deductible applies. In other words, the at-fault driver won't have to pay out-of-pocket for the other driver's repairs.  However, if a driver damages their own vehicle and wants to make a claim for repairs under their own collision coverage, they would likely owe a deductible. The amount they would owe varies depending on the policy.
