The reason car insurance is so cheap in Wisconsin is a bit of a mystery. While not a huge magnet for severe weather it does receive its fair share of snow in the winter and tornadoes in the summer. Flooding is not uncommon and rising rivers point to spring flooding this year. Flood damage is covered by comprehensive coverage, which is not required in most states, if you want your vehicle to be fully covered, you will need to carry this optional coverage.
Collision insurance is a coverage that helps pay to repair or replace your car if it's damaged in an accident with another vehicle or object, such as a fence or a tree. If you're leasing or financing your car, collision coverage is typically required by the lender. If your car is paid off, collision is an optional coverage on your car insurance policy.
