Buckling up is the best protection if you find yourself in a crash. Remember to lead by example and always fasten your seat belt before you hit the road. Encourage your passengers to do the same!
According to Wisconsin Law, all drivers and passengers over the age of four are required to wear seatbelts. Police can pull over and ticket drivers that aren't wearing seat belts. The fine for not wearing your seat belt is typically $10, but it can be more depending on the age of the unrestrained passenger.
