Question: On a multi-lane highway, slower traffic should:

Answer options:

• Stay in the left lane ✅ Stay in the right lane
• Use any lane
• Use the shoulder

Correct answer: Stay in the right lane

Explanation: Under the Québec Highway Safety Code, slower traffic must stay in the right lane because the left lane on multi-lane highways is reserved primarily for passing. Remaining in the left lane or choosing any lane arbitrarily impedes traffic flow and creates safety hazards, while the shoulder is strictly reserved for emergencies and is never a driving lane. SAAQ regulations dictate that slower-moving vehicles must keep to the right to allow faster traffic to pass safely on the left. On the Class 5 knowledge test, mastering lane-use rules is highly relevant, as questions frequently evaluate highway lane etiquette, passing protocols, and maintaining safe traffic flow.
