Question: Before changing lanes you should:

Answer options:

• Just check the mirror ✅ Check mirrors and look over your shoulder for blind spots
• Signal only
• Honk the horn

Correct answer: Check mirrors and look over your shoulder for blind spots

Explanation: To change lanes safely under ICBC guidelines, you must check your mirrors and perform a shoulder check to detect vehicles in your blind spots. Just checking mirrors is insufficient because rearview and side mirrors have blind spots where adjacent vehicles can be easily hidden. Signaling alone does not ensure the lane is clear, and honking is unnecessary and improper. The underlying rule of safe lane changes requires complete visual verification before any lateral movement. On the BC Class 7 road test, performing a shoulder check is a critical safety action, and failing to do so is a major error that can lead to an immediate fail.
