Final answer:
To steer a motor vehicle being towed or pushed by another vehicle, you need a valid driver's license because you are still operating a vehicle on public roads and must comply with traffic laws.
Step-by-step explanation:
To steer a motor vehicle that is turned off and in neutral, being towed or pushed by another vehicle, you will need a valid driver's license. Even though the vehicle is not being powered by its own engine, the person steering it is still operating a vehicle on public roads. Therefore, according to traffic laws, a valid driver's license is necessary to maintain the safety and legality of the situation. Depending on the jurisdiction, failing to have a driver's license while operating any motor vehicle, whether it's under its own power or being towed, could result in legal penalties.
