According to the Federal Highway Administration (FHWA), the rate of traffic fatalities is three times higher at night than during the day.1 One of the most important factors contributing to this tragic difference is that nighttime drivers simply lack the visual information they receive during daylight hours. 3M™ Reflective Markings increase visibility at night—helping give motorists the visual cues they need to improve safety.
The motoring public shares roads with large vehicles that--when stopped or at crossings--have the potential to become dangerous obstacles, particularly at night. Semi-tractor trailers, rail cars, school buses, emergency response apparatus and waste management vehicles all have regulations or standards for retroreflective markings for nighttime visibility.
Retroreflection occurs when light is returned back to its source. For retroreflective sheeting used in traffic safety applications, light return can be accomplished with tiny glass beads that focus light to a mirror layer, or through advanced prismatic technology that bounces light off the walls of microscopic cube corners. Prismatic materials, such as the material used in 3M reflective markings, are much more efficient at returning light to its source.
