Difficulty: EasySpatial Awareness and Blind Spot Management

Properly adjusted side mirrors completely eliminate a vehicle's blind spots, making shoulder head checks unnecessary prior to changing lanes.

Answer: Answer

Answer

False. Side mirrors reduce the size of blind spots but cannot eliminate them completely; a shoulder head check is always required before changing lanes.
The statement is false because even wide-angle or accurately adjusted side mirrors leave blind spots. Drivers must physically turn their head to check over their shoulder before changing lanes or merging.

Step-by-Step Solution

1
Evaluate mirror coverage limits
Recognize that rearview and exterior side mirrors leave areas directly adjacent to the rear quarters of the vehicle unobserved.
Vehicle body pillars and optical angles naturally create visual gaps that mirrors cannot capture.
2
Identify proper blind spot checking procedure
Confirm that turning the head for a shoulder check is required to verify clear space before moving into another lane.
Direct visual inspection is the only reliable method to check for vehicles, motorcycles, or bicyclists traveling in blind spots.
