Some companies sell standalone policies for rental cars if you don’t want to buy insurance at the counter. Generally, you need to decline the rental company’s coverage to use these.
Bonzah
Bonzah sells insurance starting at $7.99 per day that pays out for up to $35,000 in repairs or replacement of the vehicle. It’s primary insurance, so it pays out before your own insurer. Policies generally cover travel abroad, but check the fine print.
Insure My Rental Car
Insure My Rental Car offers loss damage waivers covering up to $100,000 in damage to your rental vehicle. You can purchase coverage for anywhere from a day (starting at $9.75) to a year. The policy provides primary coverage so you don’t need to use your own auto insurance first. Policies may also extend to rentals outside the U.S.
Rental Cover
Rental Cover offers no-deductible policies that count as primary coverage so you wouldn’t need to make a claim to your auto insurer first. Coverage options vary by country. Rental Cover doesn’t list prices on its website but claims to be up to 50% cheaper than the rental desk.
Sure
Sure offers rental car insurance that covers up to $100,000 worth of damage to a vehicle, plus any of your belongings inside of it. The coverage also includes flat tires and lost keys, and you can get an online quote from its website.
