Minimum Auto Insurance Requirements in Idaho

Idaho requires all drivers to carry minimum liability coverage of 25/50/15 (bodily injury per person / bodily injury per accident / property damage).

What does 25/50/15 mean?

The three numbers represent your minimum coverage limits (in thousands of dollars): the first is the maximum per person for injuries you cause, the second is the total maximum per accident, and the third covers property damage you cause to others.

While minimum coverage meets legal requirements, it may leave you financially exposed in a serious accident. Full coverage adds collision and comprehensive to protect your own vehicle as well.

About 8.8% of drivers in Idaho are uninsured, which is near the national average of about 12.6%.
