Question: In Alberta, black ice is most likely to form:

Answer options:

• At noon ✅ On bridges, overpasses and shaded areas in cold weather
• On dry asphalt
• On gravel

Correct answer: On bridges, overpasses and shaded areas in cold weather

Explanation: According to the Alberta Driver's Guide, black ice is a thin, nearly invisible layer of ice that forms quickly on cold surfaces. Bridges, overpasses, and shaded areas are highly susceptible because cold air circulates both above and below these structures, lowering their temperature rapidly, while shade prevents the sun from melting frost. Conversely, noon is typically too warm for new ice formation, dry asphalt lacks the required moisture, and gravel surfaces do not sustain slick, continuous sheets of black ice. Class 7 exam candidates must understand winter road hazards, as identifying where traction is compromised is vital for safe driving and passing the knowledge test.
