Question: What is the primary risk of driving with worn tires?

Answer options:

• Increased fuel consumption. ✅ Reduced traction and increased stopping distance, especially in wet conditions.
• A louder ride.
• Damage to suspension components.

Correct answer: Reduced traction and increased stopping distance, especially in wet conditions.

Explanation: The correct option is correct because worn tires lose their tread, which is essential for channeling water away and maintaining contact with the road, directly causing reduced traction and much longer stopping distances. While worn tires might slightly affect noise levels, fuel economy, or ride comfort, these are minor economic or physical side effects rather than the primary safety hazard. Official Alberta driving rules emphasize that adequate tire tread is critical for maintaining vehicle control and stopping safely. On the Class 7 exam, prioritizing immediate safety risks, such as traction loss, over minor mechanical or economic consequences is key to selecting the correct answer.
