What percentage of conspicuity coverage is required for rear bolster and under ride protection?

The requirement for full-width conspicuity coverage for rear bolsters and underride protection is essential for enhancing the visibility of trailers and trucks. Full-width conspicuity coverage ensures that these critical areas are highly visible to other road users, particularly at night or in low-light conditions. This visibility helps to reduce accidents and enhance safety by making the presence of trailers more apparent, thereby preventing collisions.

Other coverage options, such as percentages, do not fully satisfy the safety regulations aimed at ensuring that all parts of the rear bolster are detectable. By mandating full-width coverage, the regulations provide uniformity and maximum visibility which is crucial in protecting not only the trucks and trailers themselves but also the surrounding drivers and pedestrians.

This approach underscores the importance of overall visibility in securing safer roadways and aligning with best practices in vehicle safety standards.
