Final answer:
The correct answer is option b. a valid driver's license. The correct answer is that it is illegal to steer a motor vehicle while it is being pushed or towed if you don't have a valid driver's license.
Step-by-step explanation:
In most jurisdictions, it is a legal requirement that a person steering a motor vehicle, even if it is being pushed or towed, must have a valid driver's license. This is because they are effectively in control of the vehicle and must be qualified to manage its movement, ensuring that they can respond appropriately to traffic conditions and operate the vehicle safely if it starts. Steering a vehicle without a valid license can be seen as operating a motor vehicle without being duly authorized, which carries potential legal consequences. The concept of effective demand in economic terms, which states that demand is only effective when backed by the ability to pay, can be analogous to the requirement for a driver's license: just as you have no effective demand for a car if you can't pay for it, you also cannot legally steer a motor vehicle without a license.
Even when a vehicle is inoperative, the person steering must be licensed as they are in control of its movement.
It is illegal to steer a motor vehicle while it is being pushed or towed if you don't have a valid driver's license. Driving a vehicle requires a driver's license to ensure that the person behind the wheel has met the legal requirements and possesses the necessary skills and knowledge to operate a vehicle safely.
Having a valid driver's license demonstrates that the person has passed the required tests, understands the rules of the road, and is aware of their responsibilities as a driver. It also serves as proof that the individual has received the necessary training and possesses the ability to control and maneuver a motor vehicle.
A driver's license is essential for public safety as it helps ensure that drivers on the road have the necessary qualifications and knowledge to prevent accidents and promote responsible driving behavior.
