Idaho-Specific Considerations

Wildlife Collisions

Idaho has significant deer, elk, and moose populations. Animal strikes are common on rural highways. Comprehensive coverage is essential—collision does NOT cover animal strikes.

Winter Driving

Mountain passes and severe winter weather create hazardous driving conditions. Single-vehicle winter accidents are common—collision coverage is valuable.

Modified Comparative Fault

Idaho follows a 50% bar rule. You can recover damages if you're 49% or less at fault. At 50%+, you recover nothing.

The Boise Effect

Boise's explosive growth is increasing traffic density and accident rates. Expect Treasure Valley rates to rise faster than the rest of the state over coming years.
