Countermeasures to Keep Vehicles on Roadways

In the United States, over half of all traffic fatalities involve a roadway departure. The most cost-effective solution to reduce the number of crashes, injuries, and fatalities due to roadway departure is to strategically focus efforts on implementing countermeasures that will keep the vehicles on roadway.

Improving pavement friction, alerting drivers with rumble strips, enhancing delineation along horizontal curves, and improving nighttime visibility are effective practices that FHWA encourages agencies to explore in order to keep vehicles on the roadway.
