Your bus is equipped with a ramp operated by external power or lift operated by external power. What must you check regularly?

You answered correctly. When your bus is equipped with a powered ramp or lift, you must regularly check the safety devices, such as the reversing device, to ensure safety during operation. It is also important to check the indicators and acoustic signals for the ramp, as these help alert passengers and others nearby when the ramp is being used. These checks help prevent accidents and ensure safe use for all passengers, especially those with limited mobility. The last answer about checking if the ramp or lift works while the bus is moving does not apply, since ramps and lifts should never operate while the bus is moving for safety reasons. Always focus on regular checks of safety and signaling equipment related to ramps and lifts.
