What percentage of a trailer must be covered with reflex tape according to regulations?

The regulation stating that trailers must have at least 50% of their perimeter covered with reflex tape ensures that they are visible to other drivers, especially in low light conditions. The purpose of reflex tape is to enhance visibility and safety on the road, reducing the likelihood of accidents involving trailers. This requirement is based on standards designed to ensure that trailers are adequately marked to prevent collisions by making them conspicuous to passing vehicles.

Having at least half of the trailer’s perimeter covered means that the most critical areas of the trailer are highlighted, particularly the edges and rear, which are vital zones where visibility matters most. The choice to set this limit at 50% strikes a balance between sufficient marking for safety and practicality for trailer owners.

In contrast, other percentages would not meet the regulatory intent effectively. For instance, having only 25% coverage might leave significant portions of the trailer unmarked, leading to potential visibility issues. Conversely, a requirement for 75% or 100% coverage might impose undue burdens on trailer owners without significantly contributing to safety. Therefore, the regulation for at least 50% provides a practical and effective safety measure.
