Question: Worn tires increase the chance of:

Answer options:

• Better grip ✅ Hydroplaning and longer stopping distances
• Lower fuel use
• Improved braking

Correct answer: Hydroplaning and longer stopping distances

Explanation: Adequate tire tread is crucial under Québec’s Highway Safety Code to channel water away from the contact patch. Worn tires lack sufficient tread depth, which drastically increases the risk of hydroplaning on wet roads and significantly extends stopping distances. Conversely, worn tires severely degrade traction and braking performance, meaning options suggesting better grip, improved braking, or lower fuel use are incorrect. Recognizing how tire wear affects vehicle control and stopping distances is a core component of the SAAQ theory exam's safe-driving questions, as proper tire maintenance is vital for preventing wet-weather collisions.
