Final answer:
Place warning devices at 10 feet, 100 feet, and 200 feet toward approaching traffic when stopped on a one-way or divided highway to alert other drivers.
Step-by-step explanation:
When you must stop on a one-way or divided highway, you should place your warning devices at distances of 10 feet, 100 feet, and 200 feet toward approaching traffic. This helps provide other drivers with ample warning that there is a stopped vehicle ahead, allowing them time to slow down or change lanes if necessary.
Understanding the stopping distances for vehicles under different road conditions and driver reaction times is crucial in determining safe placement of warning devices. For instance, a car traveling at 30.0 m/s will require different stopping distances on dry versus wet concrete, and the driver's reaction time also plays a significant role in the total stopping distance.
The correct answer is 3. 50 feet, 100 feet, and 150 feet toward approaching traffic.
When stopping on a one-way or divided highway, you should place your warning devices 50 feet, 100 feet, and 150 feet toward approaching traffic. These warning devices could include flares, reflective triangles, or hazard lights. The purpose of placing the devices at these distances is to alert approaching vehicles of your stopped position and give them enough time to slow down and change lanes if necessary.
Placing warning devices at these distances helps to enhance the safety of both the stopped vehicle and other drivers on the road.
