Michigan Commercial Driver's License (CDL) Practice Exam

Which steering problem must be fixed before driving?

1. Steering that is too tight

2. Steering play in excess of 10 degrees (2 inches on a 20-inch wheel)

3. Everything should be checked but not necessarily fixed

4. Loose steering wheel cover

The correct answer is: Steering play in excess of 10 degrees (2 inches on a 20-inch wheel)

Steering play in excess of 10 degrees is a significant issue that must be addressed before driving. Excessive steering play can lead to a lack of precise control over the vehicle, which can be dangerous, especially in emergency situations or when navigating tight turns. It indicates that there is too much movement in the steering mechanism, which could result in the inability to control the vehicle accurately. This level of play increases the risk of losing control, particularly at high speeds or in critical driving scenarios. In contrast, a steering that is too tight may still allow for safe vehicle operation but can lead to driver fatigue over time. Similarly, while definite steering issues should be checked, not every small concern necessitates immediate correction, and a loose steering wheel cover doesn't affect the vehicle's steering mechanism or safety directly. Ensuring proper steering functionality is essential for effective vehicle handling, making addressing excessive steering play a crucial safety measure before driving.
