How Temporary Car Insurance Works

What temporary car insurance covers and when you need it

Temporary car insurance is a short-term policy that covers you for days or weeks instead of months or years. You buy it when you need a car for a limited time — renting a vehicle, borrowing one from a friend, or driving a car you just bought before your regular policy starts. The coverage works the same way as standard auto insurance: it pays for damage you cause to other people's property, medical bills from an accident you caused, and damage to the car itself if you pay for collision coverage.

In South Carolina, you cannot legally drive any car without insurance. If you rent a car or borrow one and do not have coverage, you are breaking the law and risking a fine. Temporary policies exist because your regular home insurance does not cover rental cars, and a rental company's coverage often has high deductibles or does not cover damage you cause to other drivers.

How long you can keep a temporary policy depends on the insurance company. Most allow policies from one day to 28 days. Some companies will renew a short-term policy if you need the car longer, but they treat each renewal as a new policy with a new application and fee.

Key Takeaways

• Temporary car insurance in South Carolina covers liability (damage you cause to others) and can include collision coverage (damage to the car you are driving) for as little as one day.
• You can buy a temporary policy online or by phone in minutes, and coverage usually starts immediately or within a few hours.
• The cost depends on the car you are driving, your age and driving record, and how many days you need coverage — a 7-day policy costs less than seven separate 1-day policies.
• Rental car companies offer their own coverage, but it often has a high deductible; comparing it to a temporary policy from an insurance company usually saves money if you need the car for more than a few days.
• If you are borrowing a car from someone you know, your own car insurance may already cover you — call your agent before buying temporary coverage.

How to buy temporary car insurance

You can buy a temporary policy from most major insurance companies — State Farm, Geico, Allstate, Progressive, and others all offer short-term coverage. You can also buy through independent agents or online brokers that compare quotes from multiple companies.

To get a quote, you will need the vehicle identification number (VIN) of the car you are driving, your driver's license, and your driving history. If you are renting, the rental company will give you the VIN when you reserve or pick up the car. If you are borrowing, ask the owner for it. The quote takes 5 to 15 minutes, and you can buy the policy immediately. Coverage usually starts within hours, though some companies offer same-day or next-day options.

You will choose how much liability coverage you want. South Carolina requires a minimum of $25,000 in bodily injury coverage per person and $50,000 per accident, plus $25,000 in property damage coverage. Most people buy higher limits — $100,000 per person and $300,000 per accident — because a serious accident can cost far more. You will also decide whether to add collision coverage (which pays for damage to the car you are driving) and what deductible you want. A higher deductible means a lower premium but you pay more out of pocket if there is an accident.

Cost and how it compares to rental company coverage

A temporary policy for one day typically costs $15 to $50, depending on the car, your age, your driving record, and the coverage limits you choose. A 7-day policy usually costs $60 to $150. Longer policies are cheaper per day — a 28-day policy might cost $200 to $400. These are rough ranges; your actual quote will depend on the specific vehicle and your personal information.

Rental car companies offer their own damage waiver, which means you do not have to pay if the rental car is damaged. However, the waiver often costs $15 to $30 per day and has a high deductible — sometimes $1,000 or more. If you rent for a week, the rental company's coverage could cost $105 to $210 just for the waiver, plus you still owe the deductible if something happens. A temporary insurance policy for the same week might cost $80 to $150 with a $500 or $1,000 deductible you choose, and it covers liability to other people as well.

If you are renting for only one or two days, the rental company's waiver might be cheaper. If you are renting for a week or longer, a temporary insurance policy usually costs less overall and gives you better protection.

Temporary coverage for borrowed cars

If you are borrowing a car from a friend or family member, check your own car insurance first. Many standard policies cover you when you drive someone else's car, as long as you have permission. Call your insurance agent and ask whether your policy covers borrowed vehicles. If it does, you do not need temporary coverage.

If your policy does not cover borrowed cars, or if you do not have your own car insurance, you will need temporary coverage for the borrowed vehicle. The process is the same as for a rental: get the VIN, get a quote, and buy the policy. Make sure the car's owner knows you are insured before you drive it.

Some insurance companies offer a "non-owner" policy instead, which covers you when you drive any car you do not own — whether it is a rental, a borrowed car, or a car-sharing service vehicle. A non-owner policy is cheaper than temporary coverage for a specific car if you expect to drive different vehicles over time, but it does not cover damage to the car itself, only liability to other people.

What temporary policies do not cover

Temporary car insurance covers accidents and liability the same way a regular policy does, but it does not cover everything. It does not cover wear and tear, mechanical problems, or damage from things like weather or theft — unless you add comprehensive coverage, which is separate from collision coverage and usually costs a few dollars more per day.

It also does not cover damage you cause if you are driving under the influence, racing, or using the car for commercial purposes like food delivery or rideshare. If you are renting a car to drive for Uber or DoorDash, you need commercial coverage, not temporary personal coverage. Check the rental agreement and your insurance policy to make sure you are covered for what you are doing.

Temporary policies also do not cover passengers' medical bills beyond what your liability coverage includes. If you want coverage for your own medical bills or your passengers' bills regardless of who caused the accident, you need to add medical payments coverage or uninsured motorist coverage, which most temporary policies allow you to add for a small extra cost.

How to use your temporary policy if you have an accident

If you are in an accident while driving with temporary coverage, the process is the same as with a regular policy. Call the police if anyone is injured or there is significant damage. Get the other driver's name, phone number, address, insurance company, and policy number. Take photos of the damage and the accident scene. Write down what happened while it is fresh in your mind.

Then call your insurance company and report the accident. Have your policy number ready. The company will ask you what happened, take a statement, and tell you what to do next. They may send an adjuster to look at the damage, or they may handle it over the phone. Do not admit fault or sign anything except the accident report the insurance company gives you.

If the other driver's insurance is paying, your company will work with them. If you are at fault, your liability coverage pays for the other driver's car and medical bills up to your coverage limits. If you added collision coverage, it pays for damage to the rental or borrowed car after you pay your deductible.

Frequently Asked Questions

Can I buy temporary car insurance for a car I just bought?

Yes. You can buy a temporary policy for the day you buy the car and drive it home, then switch to a regular policy once you have registered it and decided on long-term coverage. Some insurance companies will let you buy temporary coverage for a few days while you shop for a regular policy.

What if I need coverage for longer than 28 days?

Most temporary policies max out at 28 days. If you need coverage longer than that, you should buy a regular auto insurance policy instead. It costs less per day for longer periods and gives you more flexibility. Some companies will renew a temporary policy, but each renewal is treated as a new policy with a new application and fee.

Do I need temporary coverage if the rental company includes insurance?

The rental company's coverage usually has a high deductible and may not cover all types of damage. Compare the cost of the rental company's waiver to a temporary policy quote. For rentals longer than a few days, a temporary policy is often cheaper and covers more. For one-day rentals, the rental company's waiver might be the better deal.

Will temporary car insurance affect my regular insurance rates?

No. A temporary policy is separate from your regular policy. If you have an accident while using temporary coverage, it will not show up on your regular policy's record unless you also own the car. If you are renting or borrowing, the accident is recorded under the temporary policy only.

Can I buy temporary coverage if I have a bad driving record?

Yes, but it will cost more. Insurance companies charge higher premiums for drivers with accidents or traffic violations. You can still get a quote and buy coverage — you just pay a higher rate. Some companies specialize in high-risk drivers if you cannot find coverage elsewhere.
