Renting a car in San Diego is part of life here. Maybe you’re picking up family at San Diego International, planning a drive up the coast, or heading toward the Mexican border. Visitors rent here constantly too, and California has some of the clearest rental car rules in the country.
Here is what San Diego drivers should know before they book. Our main guide to rental car insurance coverage covers the full picture, and our personal auto insurance page can help you review what your own policy carries over. Start with two questions before you reach the counter. Do your liability, comprehensive, and collision coverage extend to a rental? And is your credit card benefit primary or secondary?
What California’s damage waiver rules say
California law spells out what a rental company’s damage waiver has to do, and it names the situations where the waiver can be excluded. Those include driving under the influence, using the car for hire, letting an unauthorized driver behind the wheel, or taking the car outside the United States. The law also limits what a rental company can charge you for damage when you decline the waiver, and it requires the company to tell you the waiver may duplicate your own insurance. These rules work in your favor, but they do not replace your own coverage.
Planning a trip to Tijuana or Baja
Many U.S. auto policies stop at the border and do not cover you in Mexico. A California damage waiver can also be excluded once the car leaves the United States. Many rental companies restrict border crossings, and those that allow them usually require you to buy Mexican liability insurance separately.
Why California liability limits deserve a second look
California raised its minimum liability limits in 2025, but the minimums are still far below what a serious crash can cost. Our California car insurance requirements guide explains the rules in more detail. You may also want higher limits, with an umbrella layered above them.
A quick checklist before you drive off
- Confirm what your auto policy covers on a rental, including loss of use and fees.
- Pay with the card whose benefit you plan to use, and read its vehicle and day limits.
- List every driver on the rental contract.
- Photograph the car before you leave the lot and again when you return it.
