Retro-reflectivity and Nighttime Visibility

Reduced nighttime visibility drastically increases the risk of traffic fatalities. About half of traffic fatalities occur at night (http://safety.fhwa.dot.gov/roadway_dept/night_visib/). On rural roadways there tend to be fewer streetlights, so visibility is typically provided by vehicle headlights. Retro-reflectivity materials and coatings that are used for both signs and pavement lane markings can increase nighttime visibility.

This section provides resources and trainings on the use of retro-reflectivity to increase nighttime visibility.
