A car insurance deductible refers to the amount of money you agree to pay out of pocket when you file an insurance claim. Once you pay this specific amount, your insurance company can then step in to help cover the remaining cost of your damages, but only up to your policy limit. Typically, a deductible is required with collision coverage, which is coverage that would protect you when you don’t cause an accident. You may also have to pay a deductible with comprehensive coverage and, in some cases, with underinsured or uninsured coverage.
