You don’t mind loaning your car out occasionally. Sometimes a buddy needs a lift somewhere but you can’t get away. Maybe your mom and dad are visiting and there’s no need for them to rent a car when you have a second vehicle. But before you are so generous with your keys, you may want to learn a bit about permissive drivers.
Most auto policies allow for permissive drivers, that is, drivers operating your vehicle with your permission. Often, their own auto policies will follow them while driving another vehicle. However, your coverage would be considered primary. Their insurance may cover some medical expenses and possibly supplement if your limits are maxed out.
What you need to watch out for are people driving your vehicle who should be on your policy. For example, your sister is visiting for a week or so from out of town. She will likely be covered. However, if that same sister is moving here and staying at your place until she finds a job, which is a different story, especially if she is using your vehicle to go on job interviews. If your assistant uses your car to run errands for you, he/she needs to be on your policy.
If you have teenage drivers living in your home, you are sometimes forced to add them to your policy. Otherwise, they will be specifically excluded from driving any of your vehicles.
Just something to keep in mind: California Vehicle Code Section 1715 states: “Every owner of a motor vehicle is liable and responsible for death or injury to person or property resulting from a negligent or wrongful act or omission in the operation of the motor vehicle, in the business of the owner or otherwise, by any person using or operating the same with the permission, express or implied, of the owner.”
It would likely be uncomfortable for both parties if your buddy pulled up with a giant dent in your car and no insurance coverage to fix it. Save yourself the trouble and embarrassment and check with your insurance professional to see what your auto policy covers and what it does not.
