The legislative bill SF No. 669 aims to repeal a section of the Minnesota Statutes (section 169.685, subdivision 4) related to seat belts and child restraint systems. The current law states that evidence showing whether seat belts or child passenger restraint systems were used or not used, or were installed or not installed, cannot be used in court cases involving personal injury or property damage from vehicle use. However, there is an exception in cases where the seat belt or restraint system was defectively designed, manufactured, installed, or operated. The bill proposes to remove this rule entirely, allowing such evidence to be admissible in court for any relevant cases.
