Question: Driving with worn tires increases the risk of:

Answer options:

• Better fuel economy ✅ Hydroplaning and longer stopping distance
• Engine damage
• Brake fade

Correct answer: Hydroplaning and longer stopping distance

Explanation: Driving with worn tires is highly dangerous because degraded tire tread cannot effectively channel water away from the tires, causing the vehicle to slide on wet surfaces (hydroplaning) and drastically increasing stopping distance. Worn tires do not improve fuel economy, cause engine damage, or directly trigger brake fade, which is instead caused by overheated braking system components. Under British Columbia’s Motor Vehicle Act regulations, drivers must maintain a minimum tire tread depth of 1.5 millimeters to ensure adequate road traction. On the ICBC Class 7 knowledge test, expect questions highlighting the link between tire maintenance, vehicle control, and safe stopping distances in adverse weather.
