Indiana Bureau of Motor Vehicles Permit Practice Test

In case fog reduces visibility to near zero, what is the recommended action?

1. Continue driving at the current speed

2. Pull off the road and stop

3. Turn on high beam headlights

4. Use turn signals continuously while driving

The correct answer is: Pull off the road and stop

When visibility is severely reduced due to fog, it is crucial to prioritize safety. Pulling off the road and stopping is the safest action to take. This allows you to avoid the dangers of driving in conditions where you cannot see other vehicles, traffic signals, or road signs, which significantly increases the risk of accidents. When stopped, it's important to remain aware of your surroundings. It's recommended that you turn on your hazard lights to alert other drivers of your presence. Continuing to drive when visibility is nearly zero can lead to dangerous situations, such as collisions or getting lost. Stopping safely reduces these risks significantly. Maintaining highway speed or using high beam headlights in foggy conditions can actually make visibility worse. High beams reflect off the moisture in the fog and can create a glare, obscuring your view even further. Turn signals should be used only when necessary and not continuously while driving, as that would not contribute to safety and could confuse other drivers. The response to pull off the road and stop ensures that you are taking the right measures to protect yourself and other road users.
