The multi car discount is probably one of the most common car insurance discounts. It is simple getting a multi car discount because it is basically fool proof. If more than one vehicle is on a single policy, the multi car discount is automatically applied.

• Multiple vehicles by design gets the multi car discount. The only time the discount does not apply is when the second vehicle on the policy is in storage. So the vehicles on the policy need to have PLPD coverage or more to qualify for the discount.

• Multiple car policies through the same carrier in the same household can usually still get the multi car discount. For example, if your teen driver has a separate policy but lives in the same household, the multi car discount can be applied. The multi car discount can really help reduce the high cost of insurance for a teen driver. Ask your agent if it is possible to get a multi car discount if you have multiple auto policies in your household.

• The multi car discount is added to each individual vehicle once. At the time the second vehicle is added the discount is applied to both vehicles. If a third vehicle is added, the discount is added to the third vehicle at that time. The original vehicles will remain the same. The multi car discount does not compound with more vehicles added.

• The multi car discount is actually available on policies other than your car insurance. Motorcycle policies commonly have a multi car discount. The same rules apply for a motorcycle multi car discount as it does on a car insurance policy. Boats and RVs are also eligible; however, less common because people often only own one boat or one RV.

Remember the multi car discount is nice to have, but it's unlikely for two cars to be cheaper than one on an insurance policy. It's a good idea to keep all your vehicles under one insurance carrier. Both the multi car and multi policy discount make it very difficult to financially benefit from separating your policies. Make sure you know how to get the multi car discount when purchasing car insurance.
