If the visibility is poor due to a hill or curve, what should you do?

1. Keep driving normally

2. Move the rear reflective triangle back down the road for warning

3. Use your horn to alert other drivers

4. Turn on your hazard lights

The correct answer is: Move the rear reflective triangle back down the road for warning

When visibility is poor due to a hill or curve, utilizing a rear reflective triangle back down the road serves as an effective warning signal for other drivers. This action is crucial because it helps alert those approaching the area that there is a potential hazard ahead, allowing them to proceed with caution. The reflective triangle can enhance safety by providing a visual cue, especially in low-visibility situations where drivers may not anticipate encountering a stationary vehicle or other dangers. Using hazard lights or a horn may not necessarily alert drivers far enough in advance for them to react accordingly, and continuing to drive normally can pose significant risks to both yourself and others on the road. Thus, deploying the triangle is the best practice when faced with poor visibility caused by geographic features.
