An at-fault accident stays on your car insurance record for three to five years, depending on your insurer's look-back window. That range translates to a 44% average rate increase, adding roughly $660 per year to a $1,500 policy and costing between $1,980 and $3,300 over the full look-back window before your rate returns to near pre-accident levels.
The insurer's look-back window is the key variable: a three-year window means a single accident affects three renewal cycles, while a five-year window stretches that surcharge across five policy years. Most drivers don't realize that their DMV record and their insurance record (the CLUE report) are two separate documents with different retention rules. Drivers who want to understand how accident history fits into their overall policy costs can start with car insurance basics.
