Question: A yellow sign showing a truck on rollers means:
Answer options:
- Truck checkpoint ✅ Truck-entry crossing (e.g., from a side road or yard)
- Truck rollover area
- Truck inspection
Correct answer: Truck-entry crossing (e.g., from a side road or yard)
Explanation: This diamond-shaped yellow warning sign indicates a truck-entry crossing where heavy trucks may regularly enter or cross the road ahead from side streets or industrial yards. It does not signify a truck checkpoint or inspection station, which are represented by different regulatory signs, nor does it warn of a rollover hazard, which depicts a tilting truck on a curved arrow. Under Ontario's highway traffic rules, recognizing yellow warning signs is crucial for anticipating road sharing hazards. Visual literacy of symbolized warning signs is highly tested on the G1 exam to ensure drivers proactively adjust their speed for emerging hazards.
