Collision coverage is very important for protecting your vehicle against the financial loss that comes with physical damage to your vehicle. It's not hard to get into an accident. When an accident happens, someone is always at fault, and that could be you. Collision insurance will cover damage from a collision with another vehicle, tree, pole, guardrail and most other possible roadway hazards.
Auto insurance is financial protection, and not just for the investment you made when you bought your car. After a really serious accident, bills for damage and injuries can easily reach into hundreds of thousands of dollars. If you happen to cause such a wreck, the victims could sue you. In the worst case scenario, assets such as your savings and home could be seized.
