At a corner, where should you place warning triangles for visibility?

The correct placement of warning triangles is crucial for ensuring the safety of both the driver and other road users in the event of a breakdown or emergency. Positioning the warning triangles 100 feet and 500 feet away, especially around a bend or incline, provides adequate visibility for oncoming drivers to react safely.

When placed 100 feet away, the triangles alert drivers who are approaching the stationary vehicle, giving them an early warning of potential hazards ahead. The 500-foot placement further assists vehicles that may be coming from a distance, allowing enough time for those drivers to slow down or change lanes if necessary. This strategy considers the limitations of visibility around bends and inclines, where vehicles might not be immediately visible to approaching traffic.

Other options may not provide sufficient warning or may confuse oncoming traffic. For instance, placing the triangles at the end of the street does not account for adequate warning distance. Similarly, positioning them only 200 feet back may not be enough in scenarios where visibility is compromised, such as on hills or corners. Placing them at the curb limits their visibility and effectiveness because they may not be seen until it's too late for drivers to respond appropriately.
