Nova Scotia Driving Test Practice: Ace your driving test

What should be done if fog reduces your visibility while driving?

1. Use high-beam headlights and maintain speed

2. Pull over to the side of the road

3. Use low-beam headlights and reduce speed

4. Open your windows to see better

The correct answer is: Use low-beam headlights and reduce speed

In conditions where fog significantly reduces visibility, using low-beam headlights and reducing speed is the best practice for enhancing safety on the road. Low-beam headlights are specifically designed to minimize the glare that can reflect off fog, rain, or snow, which helps the driver see better without producing a blinding effect that high beams can cause. Reducing speed is also crucial because it allows a driver more time to react to any obstacles or changes in the road conditions that may be obscured by the fog. In foggy conditions, distances can be deceptive; therefore, slower speeds give drivers a better chance to safely navigate through the reduced visibility. Pulling over to the side of the road can actually be risky, as this may lead to other drivers not seeing your vehicle, potentially resulting in accidents. Maintaining speed in foggy conditions is dangerous since it can lead to loss of control, as the likelihood of running into obstacles increases. Opening windows will not help improve visibility and could lead to distractions. Thus, using low-beam headlights and reducing speed is the most effective approach to driving safely in fog.
