When you must stop on a one-way or divided highway, you should place your reflective triangles at...

• A. 10 feet, 100 feet, 200 feet toward approaching traffic
• B. 20 feet, 100 feet, 300 feet toward traffic
• C. 5 feet, 50 feet, 100 feet behind the vehicle
• D. 40 feet, 80 feet, 160 feet away

Answer: (A)

When you must stop on a one-way or divided highway, the goal is to warn approaching drivers early enough for them to slow down safely. The three reflective triangles are placed along the roadway behind your vehicle, facing the traffic that’s coming toward you, at distances of 10 feet, 100 feet, and 200 feet from the rear of the vehicle. The closest triangle signals immediately nearby drivers, the middle one lengthens the warning for drivers further back, and the farthest triangle gives a long enough cue for high-speed traffic to react in time. This specific sequence and direction of placement provides the most effective warning on those types of highways. The other distance patterns either compress or extend the warning incorrectly or place the devices in the wrong direction, which reduces visibility and reaction time for oncoming traffic.
