A large red and white X-shaped sign posted at the side of the road means:
Show Answer & Explanation
Correct Answer: A. A railway crossing is directly ahead
The crossbuck (large red-and-white X) is the universal Ontario marker for a railway grade crossing. Seeing it signals that you must look, listen and be prepared to stop — trains cannot swerve, so vehicles bear the burden of yielding at every crossing.
Why the other answers are wrong
- B.A four-way intersection is aheadFour-way intersections use rectangular directional signs or stop/yield signage, never the crossbuck-X shape.
- C.Crosswinds — reduce speedCrosswind warnings are yellow diamond warning signs with a wind-sock symbol, unrelated to the X-shaped crossbuck.
- D.A construction X-detour beginsConstruction detours use orange 'DETOUR' arrow signage, not the red-and-white crossbuck.
