Question

Reflectors must be mounted at a height above the ground on every pole trailer, and on trucks, buses, truck tractors, trailers, semitrailers which are 80 or more inches in width. What is the minimum and maximum height at which the reflectors should be mounted?

1) Not less than 24 inches nor more than 60 inches
2) Not less than 30 inches nor more than 60 inches
3) Not less than 20 inches nor more than 60 inches

Answer 1

The correct answer is option 3, where reflectors on certain large vehicles should be mounted at a height not less than 20 inches and not more than 60 inches above the ground for safety and visibility.

Step-by-step explanation:

The correct answer is option 3, which states that reflectors must be mounted at a height not less than 20 inches nor more than 60 inches. The question revolves around safety regulations for vehicles, where proper visibility of trailers, trucks, and other large vehicles in low-light conditions is essential for preventing accidents. Reflectors play a critical role in these safety measures. They work on the principle of reflection, for instance, similar to corner reflectors found on bicycles and also as used by astronauts when they placed a corner reflector on the Moon. These reflectors ensure that light entering them is reflected back parallel to the direction from which it came, aiding in better visibility of the vehicle.

Reflectors must be mounted at a height above the ground on every pole trailer, truck, bus, truck tractors, trailers, and semitrailers that are 80 or more inches in width. The minimum height at which the reflectors should be mounted is 24 inches, while the maximum height is 60 inches. This ensures that the reflectors are visible to other vehicles on the road, improving safety.
