Question: Diamond-shaped white signs with a black diamond symbol mean what?
Answer options: ✅ HOV (high-occupancy vehicle) lane
- Bicycle lane
- Truck lane
- Emergency lane
Correct answer: HOV (high-occupancy vehicle) lane
Explanation: Under Ontario’s Highway Traffic Act, a regulatory white sign featuring a black diamond symbol strictly designates a High-Occupancy Vehicle (HOV) lane. This lane is reserved for vehicles with a specified minimum number of passengers, such as carpools, buses, and emergency vehicles, to improve highway traffic flow. While bicycle, truck, and emergency lanes have their own specific roadside markings and signs, they do not use the standard black diamond designation. Recognizing this symbol is highly relevant for the Ontario G1 exam, as drivers must understand restricted lane rules to avoid steep fines and safely navigate major multi-lane provincial highways.
