The maximum speed limit for a powered vehicle such as a motorized wheelchair is 8mph. This is the speed limit recommended by most states for safety reasons. Option A (5mph) is too slow and may hinder the efficiency of the vehicle, while option C (12mph) and D (15mph) are too fast and may pose a danger to the driver and those around them. It is important to adhere to the recommended speed limit to ensure the safety of everyone on the road.
