Question: Cruise control should NOT be used:

Answer options:

  • On dry highways ✅ On wet, icy, or slippery roads
  • On long trips
  • At posted speeds

Correct answer: On wet, icy, or slippery roads

Explanation: Operating cruise control on wet, icy, or slippery roads is highly dangerous because the system will attempt to maintain a constant speed, potentially causing the tires to spin, hydroplane, or lose traction, which leads to a severe skid. Conversely, using it on dry highways, during long trips, or at posted speeds represents its intended, safe application to reduce driver fatigue and maintain fuel efficiency. According to the SAAQ Driver's Handbook, drivers must retain manual control over acceleration in adverse weather conditions. This concept frequently appears on the SAAQ knowledge test to evaluate your understanding of vehicle technology and safe driving under poor road conditions.
