Difficulty: HardSpatial Awareness and Blind Spot Management

Adjusting side mirrors outward to the Blind Spot/Glare Elimination (BGE) setting—where the driver's own vehicle body is no longer visible in the mirror frame—completely eliminates side blind spots, making physical over-the-shoulder head checks unnecessary before executing a freeway lane change.

Answer: Answer

Answer

The statement is False. No mirror configuration eliminates blind spots entirely, and physical shoulder checks remain mandatory prior to lane changes.
The statement is false because wide mirror positioning (BGE setting) only reduces blind spots rather than eliminating them entirely. A direct chin-to-shoulder head check remains a strict legal and practical safety requirement before changing lanes or merging.

Step-by-Step Solution

1
Analyze the claim regarding wide-angle mirror setup and shoulder check necessity.
The statement asserts that BGE mirror adjustment removes all physical blind zones and makes manual head checks redundant.
Vehicle geometry and mirror optical limits leave areas adjacent to the rear quarter panels unmonitored by glass alone.
2
Compare against official DMV safety regulations.
DMV guidelines mandate an over-the-shoulder head glance prior to initiating any lane change or merge maneuver regardless of mirror equipment or positioning.
Mirrors alone cannot reliably reveal small objects, motorcycles, or rapidly merging vehicles positioned directly in blind areas.
