Question: A round sign with a black X and two letter Rs on a yellow background warns of:
Answer options: ✅ Railway crossing ahead
- Roundabout
- Rest area
- River crossing
Correct answer: Railway crossing ahead
Explanation: The round yellow sign with a black X and two letter Rs is the standard advance warning sign for a railway crossing ahead, alerting drivers to scan the tracks and prepare to stop. Incorrect options like roundabout, rest area, and river crossing are wrong because roundabouts utilize circular arrow symbols, rest areas are indicated by blue informational signs, and river crossings do not use this design. Under the Ontario Highway Traffic Act, warning signs use distinctive shapes and colours to communicate specific hazards before drivers reach them. Recognizing this railway warning graphic is highly relevant for the G1 exam, as railway safety and sign recognition are heavily tested.
