Yes, you can get car for a week, but it's not typically sold as a standard one-week policy from most major insurers. The most common and straightforward way to get short-term coverage is through a non-owner car insurance policy, which you can purchase and then cancel after the needed period, often with a pro-rated refund for the unused days. This is ideal if you're frequently borrowing or renting cars.
Another primary option is short-term car insurance from specialty providers like Dairyland or GEICO's Path-By-The-Mile program, which offer flexible terms starting from a single day. For rental cars, the most convenient solution is often the rental company's own insurance, sold daily at the counter.
It's crucial to understand that standard six-month policies are the industry norm. Short-term options usually come with a higher cost per day. Always confirm the cancellation policy to avoid fees if you cancel early.
| Short-Term Car Insurance Option | Best For | Typical Providers | Key Consideration |
|---|---|---|---|
| Non-Owner Policy (Cancel Early) | Frequent borrowing of friends' cars, gaps between owning vehicles | Progressive, State Farm | Must cancel to get refund; may have a short minimum term. |
| Specialty Short-Term Policy | Specific, known short-term needs (e.g., 1-week visit) | Dairyland, Breeze | Generally more expensive per day than standard policies. |
| Rental Company Coverage | Rental car users | Enterprise, Hertz, Avis | Easy to purchase but can be costly for a week; check your credit card's rental insurance first. |
| Pay-Per-Mile Insurance | Low-mileage drivers who need a policy but drive infrequently | Metromile, Allstate Milewise | Requires a base policy; cost-effective only if you drive very little during that week. |
| Adding to Existing Policy | Occasional drivers in a household | Most major insurers | The safest and often cheapest way if you're a occasional driver on someone else's policy. |
Before buying, check if your existing credit card offers rental car insurance as a benefit, which could save you from purchasing a separate policy altogether.

I looked into this last month when my brother visited and needed to drive my truck for a few days. The easiest thing we found was getting a "non-owner" online. It took maybe 20 minutes. He got it for a month because that was the shortest term offered, but he just canceled it after his trip was over and got most of his money back. Way cheaper and safer than risking it with no insurance.

For a single week, your best bet is often the offered directly by the rental car company. It's sold by the day, so you only pay for the exact days you have the car. It's straightforward—no long-term commitment, and everything is handled at the rental counter. Just be aware, it adds a significant daily cost to your rental fee, so factor that into your budget.

As someone who works with vehicles, I'd advise caution. While short-term policies exist, they are niche products. The most reliable method is being added as a driver to the car owner's existing policy for that specific period. This is usually the most cost-effective and seamless option, provided the primary insurer allows it. It avoids the complexities and higher premiums of standalone short-term plans.

Honestly, standard companies don't really do one-week policies. You have to think outside the box. I needed coverage for a cross-country drive after a car privately. I used a provider that specializes in short-term bonds or insurance for just a few days. It was more expensive than a regular policy, but it was perfect for my specific situation. It's out there, but you have to search for "temporary auto insurance" specifically.
