In addition to checking the left side mirror, what else must a driver do to ensure safety when changing lanes?

Accelerate quickly

Glance over their left shoulder

When changing lanes, it is crucial for a driver to ensure they are aware of their surroundings and the positions of other vehicles. Glancing over the left shoulder provides an important additional point of view that mirrors may not fully capture, particularly for vehicles that may be in a blind spot. This physical head turn helps confirm that the lane is clear and that it is safe to merge.

This practice is essential for enhancing awareness and making informed decisions, reducing the risk of collisions. Relying solely on mirrors can create blind spots; thus, physically checking over the shoulder is a key safety measure that drivers should incorporate into their lane-changing routine.
