Question: In Ontario, driving with summer tires in heavy snow is:

Answer options:

• Recommended ✅ Dangerous — significantly reduces traction
• Required
• Same as winter tires

Correct answer: Dangerous — significantly reduces traction

Explanation: Using summer tires in snow is dangerous because winter tires are formulated with special rubber compounds that remain flexible in sub-zero temperatures, whereas summer tires harden and lose critical traction. Suggesting that summer tires are required, recommended, or equivalent to winter tires is incorrect and unsafe, as summer tread patterns cannot channel snow or grip icy surfaces. According to the Official MTO Driver's Handbook, winter tires are highly recommended for Ontario winters to maintain vehicle control and shorten stopping distances. For the G1 exam, recognizing how equipment choices impact traction and safety in adverse weather is vital for passing.
