A regulatory sign reading 'NO TRUCKS IN THIS LANE' means:

Ontario road sign — Trucks are prohibited from using the marked lane
Show Answer & Explanation
Correct Answer: B. Trucks are prohibited from using the marked lane

Truck restrictions on specific lanes keep heavy vehicles out of lanes not engineered for their weight or where they would block sightlines and merging. Commercial drivers face fines and potential commercial-licence consequences for violating lane restrictions.

Why the other answers are wrong

  • A.Trucks may use the lane only during off-peak hoursThe regulatory wording is absolute unless the sign itself shows time-of-day text.
  • C.Only trucks may use the lane'Only trucks' would require a truck-only sign — entirely different signage.
  • D.The lane is open to trucks and buses togetherA combined truck/bus lane would be signed 'TRUCKS AND BUSES'; this sign excludes trucks only.
