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: Glancing over the appropriate shoulder is correct because it allows you to see areas directly beside your vehicle that mirrors miss. Relying on mirrors alone or rear-view cameras is incorrect because optical devices have physical limitations and leave blind spots on both sides. Leaning forward reduces your field of vision rather than clearing the blind spot. Under SAAQ rules, a visual shoulder check is mandatory before any lane change or turn to ensure safety. For the SAAQ practical test, examiners strictly monitor shoulder checks; failing to perform one is a critical error that can cause you to fail the road test.
