Where should the three reflective triangles be placed on a divided highway?

Placing reflective triangles correctly is crucial for safety when a vehicle is stopped on a divided highway. The correct answer indicates that the first triangle should be placed 10 feet from the rear of the vehicle, which is close enough to alert oncoming traffic without being too close to the vehicle's danger zone. The second triangle is positioned 100 feet behind the vehicle; this distance helps to warn drivers from a considerable distance, giving them enough time to react. The third triangle should be placed at 200 feet to the rear, effectively marking the hazard well ahead so that approaching vehicles are notified well in advance and can take necessary precautions.

This arrangement is a standard practice aimed at maximizing safety by ensuring that the reflective triangles are visible to drivers approaching from behind. Proper placement helps avoid accidents that may occur due to an unsuspected stopped vehicle.
