Michigan Commercial Driver's License (CDL) Practice Exam

In cold weather conditions, how should your tires perform?

1. Provide minimal traction

2. Be flat to prevent skidding

3. Provide enough traction to steer and push the vehicle through snow

4. Be under-inflated to maintain surface contact

The correct answer is: Provide enough traction to steer and push the vehicle through snow

In cold weather conditions, tires are crucial for maintaining safety and control of the vehicle. The correct answer emphasizes that tires should provide enough traction to steer and push the vehicle through snow. This is essential because snow and icy surfaces can dramatically reduce tire grip, making it necessary for tires to have adequate tread and proper design to handle those conditions effectively. Tires designed for cold weather, particularly winter tires, have specific tread patterns and rubber compounds that remain flexible in low temperatures. This flexibility allows the tires to conform better to the road surface, enhancing grip and ensuring that the vehicle can be maneuvered safely in challenging conditions. While some incorrect options suggest deficiencies in tire performance, they overlook the core function of tires in winter driving. Properly functioning tires should work to maximize traction and control, enabling safe navigation through snow and ice.
