How to Get One-Week Car Insurance

No U.S. insurer sells a true one-week policy, but four legitimate strategies get you covered. Which one is right for you depends on whether you own the vehicle and how often you need short-term coverage.

1. Buy and Cancel ($17 to $26 per week): Best if you own a car and need temporary coverage. You pay the first month upfront and get a prorated refund for the unused portion. GEICO starts at $17 weekly, making it the cheapest option for drivers who own their vehicle.
2. Non-Owner Insurance ($10 to $16 per week): Best if you borrow different cars regularly throughout the year. The cost spreads across multiple uses, making each borrowing occasion more affordable than buy and cancel.
3. Permissive Use (Free): Best if you are borrowing a friend's or family member's car once. You are covered under the owner's existing policy at no cost. Any claim affects the owner's rates though, not yours. If that matters to them, buy and cancel is the safer choice.
4. Rental Car Insurance ($15 to $30 per day): Best if you are renting a car. Counter coverage from the rental company is the simplest option. You pay only for the days you drive and can cancel anytime without fees.

Buy and cancel requires the same information as a standard policy application. Having these ready before you begin cuts the process to 15 to 20 minutes with most carriers.

• Driver's license number
• Vehicle registration and VIN
• Current insurance information if applicable
• Payment method for the first month's premium
• Names of any additional drivers who will use the vehicle

If you need to drive today, start with GEICO, Nationwide or Progressive. All three offer same-day coverage with immediate proof of insurance after purchase, faster than most carriers that require processing time before your policy goes active.

In our experience helping customers, buy and cancel is the most common solution for drivers who own their vehicle. You purchase a standard six-month policy, drive for seven days and cancel for a prorated refund. The process takes 15 to 20 minutes online and coverage starts the same day with most carriers.

The hidden costs are where drivers get surprised. Three things can push your effective weekly rate well above the table below.

• Cancellation fees. Some carriers charge $25 to $50 to cancel a policy early. GEICO, Kemper and Nationwide waive these fees entirely, which is one reason they lead our cost table. Travelers and Progressive may charge depending on your state.
• Processing fees. Administrative fees compressed into seven days can nearly double your daily cost. Ask specifically about processing fees before you purchase, not after.
• Minimum earned premiums. This is the one most drivers miss. Some carriers keep a minimum portion of your first month's premium regardless of when you cancel, typically 10% to 25% of the monthly rate. Before purchasing, ask your carrier directly: "Do you have a minimum earned premium?" If the answer is yes, factor that amount into your true weekly cost before comparing carriers.

To avoid all three fees, start with GEICO. It waives cancellation fees, has no minimum earned premium and offers the lowest weekly rate in our dataset at $17.

Non-owner insurance is a legitimate option but not always the right one for a true one-week need. Insurers require a 30-day minimum and you pay $39 to $63 upfront with no refund if you cancel after seven days. That makes the effective weekly cost $39 to $63, more than double what buy and cancel costs for most drivers.

It becomes the right choice in four specific situations:

• You borrow or rent cars multiple times throughout the year. Spreading the monthly cost across several uses brings the per-use cost down significantly, often below every other option on this page.
• You need to file an SR-22 but do not own a car. Non-owner insurance is often the only way to satisfy that requirement after a DUI or serious violation. GEICO and Progressive both file SR-22s on non-owner policies.
• Your state requires continuous coverage to keep your license active. Non-owner insurance satisfies that requirement at the lowest possible cost even when you do not own a vehicle.
• You use car-sharing platforms like Zipcar or Turo regularly. Non-owner insurance fills liability gaps that platform coverage often leaves open.

One thing to know about what it covers: non-owner insurance is liability only. It protects others if you cause an accident but does not cover damage to the vehicle you are driving. The car owner's policy pays first and your non-owner policy covers the difference if damages exceed their limits.  See our guide to the cheapest non-owners policies.

Permissive use is the simplest option for a one-time borrow and it costs nothing. Driving with the owner's permission puts you under their existing policy automatically. No application, no payment, no cancellation process.

The tradeoff is worth understanding before you rely on it. Any claim you file goes against the owner's policy, not yours. That means their rates go up, not yours. If the accident is serious enough, it could affect their coverage eligibility at renewal. Most owners do not think about this when handing over their keys, and most borrowers do not think to ask.

A few situations where permissive use does not work as expected:

1. Excluded drivers. Some policies explicitly exclude certain drivers by name. If the owner's insurer has excluded you, permissive use does not apply and you would have no coverage.
2. Commercial use. Using the vehicle for rideshare or delivery during the borrowed week voids permissive use coverage on most standard policies.
3. Frequent borrowing. If you borrow the same car regularly, most insurers expect you to be added as a named driver. Relying on permissive use for repeated use is a gray area that some carriers will dispute at claim time.

For a true one-time borrow with a car owner who understands the rate risk, permissive use is the right call. For anything more complex than that, buy and cancel gives both parties cleaner protection.

If you need car insurance for a week to drive a rental car, then buying rental car insurance is your simplest option for true one-week coverage. 

The daily rate is higher than other options on this page, but renting solves two problems at once: you get the vehicle and the insurance in a single transaction with no application, no cancellation and no refund to wait for.

Two coverages matter most.

• Collision Damage Waiver (CDW). Covers damage to the rental vehicle itself. If you have a premium credit card, check your benefits before purchasing since many cards include CDW automatically, dropping your daily cost significantly.
• Supplemental Liability Protection (SLP). Covers injuries or damage you cause to others above the rental company's minimum liability limits, which are typically very low. If you do not have an existing auto policy, carry both CDW and SLP. Without personal liability coverage behind you, the rental company's minimums leave you significantly exposed in a serious accident.

The rental company will also offer personal accident insurance and personal effects coverage. Both duplicate protection you likely already have through health insurance and homeowners or renters insurance. Skip them and focus on CDW and SLP.
