Commercial Driver License (CDL) Class B Practice Test

When a vehicle is stopped on a divided highway, placing the reflectors at the correct distances is crucial for safety. The recommended positions for the reflectors are specifically designed to alert oncoming traffic of the stopped vehicle, which is particularly important on high-speed roads where visibility can be limited. The correct choice indicates that reflectors should be positioned at 10 feet, 100 feet, and 200 feet toward approaching traffic. This arrangement allows for adequate warning to drivers who might be approaching at significant speeds. The closest reflector at 10 feet provides immediate awareness for drivers who are nearing the stopped vehicle, while the second and third reflectors placed further back serve to warn traffic even earlier and give drivers ample time to react. This systematic placement helps ensure that the reflectors are visible from various distances, thus maximizing their effectiveness in preventing accidents. Proper use of reflectors is a vital aspect of roadside safety management, especially on highways where traffic density and speed can result in dangerous conditions if drivers are unaware of a stopped vehicle ahead. Utilizing the other distance options would not provide an optimal warning to approaching traffic, as they may not cover the necessary range for safe response times by drivers.
