At what angle should all types of barricade have reflective stripes?

Reflective stripes on barricades are critical for visibility and safety, particularly in low-light conditions. The standard practice dictates that these stripes should be installed at a 45-degree angle. This orientation enhances their visibility from various approaches and distances, making it easier for drivers and pedestrians to notice the barricade well in advance. By positioning the stripes at this angle, the reflective material can effectively catch and reflect light from vehicle headlights, significantly improving safety and reducing the likelihood of accidents.

In contrast, other angles either do not provide the same level of visibility or may not be as effective in reflecting light, which could lead to confusion or lack of awareness about the barricade's presence. The 45-degree angle strikes an ideal balance between visibility and practicality in different environmental conditions.
