Question: A sign showing a snowflake means what?
Answer options:
- Ski area ✅ Bridge may be icy / slippery in cold weather
- Winter tires required
- Snow removal
Correct answer: Bridge may be icy / slippery in cold weather
Explanation: The Ontario Ministry of Transportation designates the snowflake warning sign to alert drivers that a bridge or overpass ahead may be icy or slippery in cold weather. This hazard exists because cold air circulating underneath elevated structures causes them to freeze faster than the surrounding roadway. The sign does not indicate a ski area, mandate winter tires—which are not legally required by signs in Ontario—or represent snow removal zones. Correctly identifying this warning sign is a critical G1 exam requirement that tests a driver's ability to recognize winter road hazards, prompting them to proactively reduce speed and avoid sudden braking when approaching bridges in cold conditions.
