Question: A diamond (♦) symbol on the road or sign indicates a lane reserved for:
Answer options:
- Trucks ✅ High Occupancy Vehicles (HOV)
- Buses only
- Emergency vehicles
Correct answer: High Occupancy Vehicles (HOV)
Explanation: In Ontario, a diamond symbol painted on the road or shown on a sign officially designates a reserved lane for High Occupancy Vehicles (HOV). This regulatory marking helps improve traffic flow by encouraging carpooling and transit use. While buses and certain emergency services can use these lanes, the symbol does not restrict the lane exclusively to trucks, buses only, or emergency vehicles. On the G1 knowledge exam, identifying road markings is a heavily tested topic. Memorizing that the diamond represents HOV lanes, which typically require a minimum number of passengers, is crucial for passing the rules of the road section.
