How should the steering wheel be checked?

Answer: C — Both A and B

The correct choice indicates that both the lack of excessive play and the smooth operation of the steering wheel are essential during the pre-trip inspection. Having no excessive play means that the steering wheel should not have too much free movement when you turn it. Excessive play can indicate issues with the steering system, including worn components, which may jeopardize the driver's control over the vehicle. A loose or imprecise steering wheel can lead to difficulties in steering response, affecting safety while driving. Additionally, the steering wheel should operate smoothly. This means that as the driver turns the wheel, it should move without resistance or sticking. A smooth operation is crucial for ensuring that the driver can adjust direction quickly and accurately, which is particularly important in emergency situations. Together, these aspects are vital for the overall safety and functionality of the vehicle and are both integral components that a driver must check to ensure that the steering system is in good condition before operating the vehicle.
