You must purchase insurance before buying a car. If you already have a policy, there's typically a grace period of seven to 30 days before you have to add your new vehicle to your insurance plan.
At what age is car insurance cheapest?
Once young drivers gain more experience and hit age 25, their car insurance costs drop about 33%. Costs continue to generally decline with each birthday. Once drivers reach age 50, they'll see their best rates. Around age 60, however, auto insurance costs begin to increase and compare to what drivers see in their 40s.
Should I shop around for car insurance every 6 months?
It's recommended that you shop around for car insurance quotes at least once a year. However, to make sure you're getting the absolute best rates, consider shopping for new quotes every six months — the length of a standard policy. An easy way to remember when to shop is to watch for the end of your current policy.
