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: Using cruise control on wet, icy, or slippery roads is dangerous because if your tires lose traction or hydroplane, the system may accelerate to maintain speed, causing a severe skid. Conversely, operating cruise control on dry highways, during long trips, or at posted speed limits represents safe, ideal usage that reduces driver fatigue. Under ICBC safety guidelines, drivers must never use cruise control in poor weather, hazardous road conditions, or heavy traffic. Mastering how traction affects automated vehicle systems is a vital practical safety concept frequently tested on the BC Class 7 knowledge exam.
