Question: To check your blind spot before changing lanes you should:

Answer options:

• Rely on mirrors alone ✅ Glance over the appropriate shoulder
• Lean forward
• Use rear camera only

Correct answer: Glance over the appropriate shoulder

Explanation: To safely complete a lane change, drivers must glance over the appropriate shoulder because car mirrors have inherent blind spots that cannot capture vehicles traveling directly beside them. Relying solely on mirrors or backup cameras leaves these critical hidden areas unmonitored, while leaning forward fails to provide the necessary view of the side-rear traffic lanes. Under ICBC rules, a proper shoulder check—turning your head at least 90 degrees toward the direction you intend to move—is legally required before any lateral maneuver. On the Class 7 road test, failing to shoulder check is a major error that can lead to an immediate automatic failure.
