An at-fault accident stays on your car insurance record for three to five years in most states. Per MoneyGeek's analysis, the average monthly premium rises from $290 to $420, a $130/month ($1,565/year) increase at renewal.
That window is not fixed. Your insurance company sets its own lookback period, and only that window affects what you pay — not the DMV's. Progressive closes the at-fault window after three years. Allstate applies five. At a five-year company, one at-fault accident costs $7,825 in total rate increases before your premium returns to normal.
