How many points of contact should a wheelchair have according to regulations?

Answer: B — Three points

According to regulations, a wheelchair is required to have three points of contact for secure and safe operation during transportation. This guideline ensures that the wheelchair is stable and minimizes the risk of tipping over or sliding while the vehicle is in motion. The three points of contact typically refer to the two rear wheels and the front caster or one rear wheel and two front casters, creating a stable triangle that enhances balance. By adhering to this standard, school bus operators help ensure the safety of passengers who use wheelchairs, providing them with a secure environment during transit. Having fewer than three points of contact can compromise stability, while more than three may not be necessary or feasible for proper loading and securing within a bus. Regulations are designed to prioritize passenger safety and promote best practices in school bus operations.
