Difficulty: EasyPassing, Overtaking, and Lane Changing Rules

Before executing a lane change to the left on a multi-lane highway, a driver has activated the turn signal and checked both the rearview and side mirrors. What essential action must the driver perform next before steering into the adjacent lane?

  1. A
    Depend exclusively on side mirrors if they are adjusted outward
  2. B
    Briefly exceed the posted speed limit to accelerate past adjacent vehicles
  3. Turn the head to perform a shoulder check into the blind spot areaAnswer
  4. D
    Sound the horn continuously while moving into the desired lane

Answer

Turn the head to perform a shoulder check into the blind spot area
Performing a direct shoulder check in the direction of the intended lane change is mandatory because vehicles traveling alongside cannot be seen in rearview or side mirrors alone.

Step-by-Step Solution

1
Identify the limitations of rear and side mirrors during lane changing maneuvers
Mirrors leave unmonitored spaces (blind spots) beside and slightly behind the vehicle
Optical reflection angles in standard mirrors cannot capture adjacent vehicles traveling in blind spots
2
Determine the required safety check before moving the vehicle into the target lane
Turning the head for a direct shoulder check verifies that the blind spot is clear
Prevents side-swipe collisions with vehicles that are hidden from mirror view
