Yes, you can typically add someone to your car for a week, but it's not as simple as a one-week policy. The standard method is to add them as a occasional driver to your existing policy for the period they'll be driving, and then remove them afterward. However, this process involves your insurer recalculating your premium for the entire term, which could lead to a higher bill even after the person is removed.
For a truly short-term solution, inquire about a non-owner car insurance policy for the other person. This type of policy provides liability coverage for someone who drives vehicles they don't own. Alternatively, if the person has their own insurance policy, it might extend permissive use coverage, protecting them (and you) when they occasionally drive your car. This is often sufficient for a one-off situation without formally adding them.
The main factors insurers consider are the driver's age, driving record, and your relationship to them. Adding a young driver with a poor record, even for a week, will significantly impact your premium more than adding an experienced driver with a clean history.
| Factor | Impact on Premium & Process | Best For |
|---|---|---|
| Driver's Age & Record | A teen driver or one with violations causes a larger premium increase. | Long-term planning for frequent drivers. |
| Non-Owner Policy | Provides liability coverage for the driver, not your car. Avoids changes to your policy. | Someone who frequently borrows different cars. |
| Permissive Use | Usually covered for infrequent, short-term use without formal addition. | A single, short trip by a driver with their own insurance. |
| Formal Addition to Policy | Most comprehensive coverage but can be administratively cumbersome for a single week. | A family member living with you or driving your car regularly. |
Contact your insurance agent directly to discuss the specific circumstances. They can outline the most cost-effective and compliant option for your situation, ensuring there are no gaps in coverage.

Yeah, you can, but call your company first. If it's just for a few days, like a friend visiting, their own insurance might already cover them when they drive your car. That's called permissive use. But if they're gonna be driving a lot or are a higher-risk driver, you'll probably have to add them officially. Just know that even if you remove them later, your rate might have gone up for that term.

From my experience, it's all about frequency and risk. If your college-aged kid is home for a week and will drive your car, you should add them. The potential cost of an accident without them being listed is far greater than a slight premium adjustment. For a one-time errand for a neighbor with a solid driving history, permissive use is likely fine. Always err on the side of caution and full disclosure with your insurer.

Think about the cost. Adding a driver triggers a re-rating of your . If you add a teen driver for just seven days, you might see a premium increase that lasts for the entire six-month policy period, even after you take them off. For a truly short, low-risk situation, a non-owner policy for the other driver might be a more financially sensible solution than altering your own coverage.

The simplest answer is to be transparent with your provider. Explain exactly who needs to drive the car, for how long, and why. They will tell you the best procedure based on their rules and your state's regulations. Trying to save a few bucks by not properly listing a driver can backfire badly if there's an incident, potentially leading to a denied claim. A quick call to your agent provides a definitive, safe answer.
