🤯 The Montana Mindblower

Montana had no numeric daytime speed limits from 1995-1999—just "reasonable and prudent." The Supreme Court struck it down as unconstitutionally vague. Today's 80 mph interstate limits are still among America's highest, making comprehensive coverage essential for high-speed highway driving.

Montana-Specific Considerations

Wildlife Collisions—Serious Risk

Montana ranks in the top 5 states for deer-vehicle collisions. Elk and moose strikes are even more dangerous. Comprehensive coverage is essential for Montana driving.

High-Speed Highways

With 80 mph speed limits on rural interstates, accidents tend to be more severe. Higher liability limits are recommended given the speeds involved.

Winter Extremes

Montana winters are brutal. Single-vehicle accidents on icy roads are common. Collision coverage pays for these—comprehensive does not.

Modified Comparative Fault (51%)

You can recover damages if you're 50% or less at fault. At 51%+, you recover nothing.
