Your personal auto insurance may cover rental cars, particularly if you have full coverage. Liability, collision and comprehensive coverage often extend to rental vehicles used for personal reasons.
However, your coverage might not include rental company-specific fees, such as loss of use, administrative charges or diminished value. Also, your personal auto policy typically won’t apply if you’re renting for business or driving outside the U.S. or Canada.
Before declining rental car insurance, check with your insurer to understand your policy's coverage and whether any gaps could lead to out-of-pocket expenses.
