謝謝班長! 剛剛問了, 他們回複如下, 看來最好別出事:
We received your inquiry regarding lending your vehicle to another driver, and we will be happy to answer your question.
If this person is to use your vehicle for only 1-2 weeks, it would not be necessary to add the person to your policy.
If you give permission to someone to drive your vehicle, your policy would cover the accident based on your policy contract. Insurance follows the vehicle, but insurance responsibility usually follows the policyholder. As owner of the vehicle, you may be liable for anything the driver does to the vehicle or while driving the vehicle. In some states, if you loan your car and then the borrower loans it to someone else, your coverage may still be responsible for damages.
Also, someone else's accident could cause you to lose coverage or become ineligible for a preferred rate. One thing that research has shown is that borrowed cars have a much higher probability of being involved in an accident than vehicles operated by their owners.
If this driver will operate your vehicle more than once a month on a recurring basis, please log to our Policyholder Service Center at service.geico.com to add them as a driver on your policy. After logging in, click the Drivers section under the Policy tab. On the left side of the page, please click on "Add Another Driver" to complete your request.
Thank you for using our online services. We appreciate your business and look forward to serving your insurance needs for years to come.
