If this happens, there would be a sudden loss of power to the wheels. Safety Risks: A sudden loss of power to the wheels could increase the risk of a crash. Additionally, a bus that is disabled could create the need for a transfer of passengers in an uncontrolled environment, which may create a risk of injury.
