Yes, you can get car insurance for a single day, but it's not a standard product you can buy directly online like an annual policy. The most common and practical way to secure one-day coverage is typically through a non-owner car insurance policy, which can often be written for very short terms, or by leveraging the permissive use clause in a friend or family member's existing policy if you only need to borrow their car briefly. Standard six-month or annual policies remain the norm because they are far more cost-effective for both the insurer and the driver.
For a single day of specific need, like test-driving a car you intend to buy from a private seller, your best bet is to contact an insurance agent directly. They can often bind a short-term liability policy to cover that exact period. Major rental car companies also offer daily insurance at the counter, but this only applies to their rental vehicles. It's crucial to understand that driving without any insurance, even for a day, is illegal in most states and carries significant financial risk.
The table below outlines common scenarios and the typical insurance solution for each:
| Scenario | Recommended Solution | Key Considerations |
|---|---|---|
| Test Driving a Car | Short-term non-owner policy or dealer's insurance. | Protects you against liability if you cause an accident. |
| Borrowing a Friend's Car | Rely on "permissive use" under the owner's policy. | Verify coverage with the owner's insurer first. |
| Renting a Car | Purchase the rental company's daily liability/LDW coverage. | Often more expensive than coverage from your own policy or credit card. |
| Covering a Gap Between Policies | Avoid gaps; set new policy to start before old one expires. | A lapse can lead to higher future premiums. |
| Moving a Vehicle Short Distance | Temporary "Trip" policy or tow dolly insurance. | Specific policies exist for inoperable vehicle transport. |
Ultimately, while possible, single-day insurance is situational. For any regular driving, a traditional policy is mandatory and financially smarter.

Honestly, it's a hassle. I looked into it once when I was buying a used truck from a guy on Craigslist. My own policy didn't cover test drives on cars I didn't own yet. I had to call my insurance guy, and he set up a tiny one-day liability policy. It cost me around $30 for the day. It felt like a lot for a 20-minute drive, but it was way cheaper than the risk of something going wrong. For a one-time thing, just pick up the phone and call an agent.

The most straightforward way is if you're just borrowing a car from someone you know. If the owner has a standard insurance policy, it often extends to other licensed drivers they permit to use their vehicle. This is called "permissive use." However, you should always double-check with the owner and their insurance company first. Some policies have exclusions. If you're not related to the owner or the car is for a business purpose, this coverage might not apply, and you'd need your own short-term policy.
