Final answer:
The statement is False. Turning on high beam headlights in fog will decrease the field of vision and impair visibility.
Step-by-step explanation:
The statement is False.
When driving in fog, turning on the high beam headlights will actually decrease the field of vision. The bright light from the high beams reflects off the tiny water droplets in the fog, causing a glare that can impair visibility even further and make it more difficult to see the road ahead. Instead, drivers should use their low beam headlights or fog lights, if available, as these lighting options are designed to provide better visibility in foggy conditions.
It's important for drivers to be aware of proper driving techniques in different weather conditions to ensure their safety and the safety of others on the road.
