Headlights must be turned on:

Question: Headlights must be turned on:

Answer options:

• Only at night ✅ From dusk to dawn and whenever visibility is poor
• Only in winter
• Only in fog

Correct answer: From dusk to dawn and whenever visibility is poor

Explanation: BC driving regulations require headlights to be turned on from dusk to dawn—defined as thirty minutes after sunset to thirty minutes before sunrise—and whenever atmospheric conditions like rain, fog, or snow reduce visibility to less than 150 meters. This ensure drivers can see and be seen in all low-light situations. The incorrect options are too restrictive because daytime fog, heavy summer rainstorms, or smoke also legally necessitate headlight use, not just nighttime or winter driving. Understanding this rule is highly relevant for the ICBC knowledge test, which frequently emphasizes proactive safety measures and vehicle lighting requirements under adverse conditions.
