Question: A square white regulatory sign showing a black truck symbol marks:
Answer options:
- A truck rest stop ✅ A designated truck route
- A weigh scale ahead
- No trucks allowed
Correct answer: A designated truck route
Explanation: In Ontario, a square white sign displaying a black commercial truck symbol is a regulatory sign marking a designated truck route that heavy vehicles are permitted or required to follow. The "no trucks allowed" option is incorrect because prohibitive signs feature a red circle with an intersecting slash. Signs for rest stops or weigh scales are informational or guide signs using different colors, shapes, or text. Under the Highway Traffic Act, white regulatory signs dictate mandatory traffic rules. G1 candidates must know how white regulatory signs and red prohibitory circles differ to pass the rules of the road section.
