In what situation should you place warning devices 100-500 feet behind your vehicle?

Placing warning devices 100-500 feet behind your vehicle is essential for alerting oncoming traffic, especially when there is an obstructed view. In scenarios where visibility is limited—like on curves or hills—drivers may not see your vehicle until they are very close, which increases the risk of an accident. By positioning warning devices at a significant distance, you provide sufficient notice for approaching drivers to slow down or change lanes, reducing the likelihood of a collision.

In contrast, on a flat road, a one-way highway, or when parked in a safe area, positioning warning devices at such a distance is often unnecessary since visibility is generally clear, and other drivers can easily see your vehicle. Proper placement in the case of an obstructed view is crucial for safety and compliance with traffic regulations.
