Question

Difficulty: MediumSpatial Awareness and Blind Spot Management

Properly adjusting exterior side mirrors to outward angles eliminates all blind spots, making over-the-shoulder head checks unnecessary prior to changing lanes.

Answer: Answer

Answer

The statement is False. Even with properly adjusted mirrors, drivers must always perform a chin-to-shoulder head check before changing lanes.
The statement is incorrect because side mirrors alone cannot eliminate all blind spots around a passenger vehicle. Official traffic safety standards specify that drivers must always turn their head to check over their shoulder before initiating any lane change.

Step-by-Step Solution

1
Analyze mirror coverage capabilities
Recognize that exterior side mirrors, regardless of positioning angle, leave small unmonitored zones beside and slightly behind the vehicle.
Mirrors provide a limited field of view and cannot cover the entire perimeter adjacent to the vehicle.
2
Determine the required safety procedure for lane changes
Confirm that a physical head glance over the shoulder (chin-to-shoulder check) is strictly required by DMV standards to inspect areas missed by mirrors.
Head checks ensure vulnerable road users and adjacent vehicles in blind spots are detected prior to moving laterally.
