Question: In heavy rain at highway speed you should:

Answer options:

• Use cruise control ✅ Reduce speed, increase following distance, and turn cruise control off
• Brake hard often
• Use high beams

Correct answer: Reduce speed, increase following distance, and turn cruise control off

Explanation: Heavy rain significantly reduces tire traction and visibility, increasing the risk of aquaplaning. Reducing speed and increasing following distance provides essential reaction time on wet pavement, while disabling cruise control prevents the vehicle from critically accelerating if tires lose contact with the road. Using cruise control in the rain is highly dangerous because it can trigger a sudden loss of control. Hard braking can lock the wheels and cause skidding, while high beams reflect off water droplets, severely impairing visibility. Under the Québec Highway Safety Code, drivers must adapt their speed to road conditions. Expect questions on driving in adverse weather on the SAAQ exam to test your knowledge of hydroplaning prevention.
