Best Time to Shop for Car Insurance: How Often and When

Most drivers benefit from shopping insurance every 6–12 months, especially after life changes (move, new car, teen driver) or rating events (ticket, accident) age off. Rates vary among carriers and over time.

Before you shop

  • Decide your coverage limits/deductibles so quotes are comparable.
  • Have driver, VIN, mileage, and garaging details handy.
  • Ask about discounts (bundle, telematics, pay‑in‑full, homeowner).

Use this site to get a grounded estimate first, then compare real quotes from multiple carriers.

Signals that it’s time to shop

  • Moved states or ZIP codes
  • Added/removed a driver (teen, spouse)
  • Changed vehicles or annual mileage
  • Violations/claims aging past 36 months
