Which exercise tests a driver's ability to adjust mirrors and make minor steering corrections?

The straight line exercise is specifically designed to assess a driver’s proficiency in steering control and mirror adjustment. During this exercise, the emphasis is on maintaining a straight path while making small course corrections as needed. This simulates real-world driving scenarios where drivers must frequently adjust their position within the lane.

In addition, while navigating in a straight line, drivers are encouraged to properly adjust their mirrors to enhance their visibility and awareness of surrounding conditions. This practice reinforces the skill of making swift and accurate adjustments to maintain optimal driving control, which is essential for effective vehicle operation in emergency situations.

On the other hand, the other options test different skills: the obstacle course focuses on maneuvering around objects; the figure-eight exercise emphasizes turning control in tighter spaces; and parallel parking assesses the ability to park the vehicle efficiently. Each of these exercises has its unique purpose, but it is the straight line exercise that uniquely hones in on the combination of mirror adjustments and minor steering corrections.
