Horizontal curves have higher crash rates than other highway segments. Learn how improving visibility on horizontal curves can improve driver safety.

In rainy, nighttime conditions, the pavement markings that define lanes can become difficult to see. Learn how pavement marking visibility plays a major role in helping drivers navigate, stay in their lanes, and get home safely.

Help reduce traffic accidents at intersections by using traffic signal backplates with retroreflective borders. Highly visible traffic lights can alert distracted drivers.

To help increase road safety, consider putting your roads on a diet. A road diet reduces lanes of traffic to improve efficiency and help make roads safer for drivers, pedestrians and bicyclists.

Roundabouts reduce the number of conflict points at intersections, which lowers the number of traffic accidents. Choose the right road signs and pavement markings for roundabouts.
