Volume 06: A Guide for Addressing Run-Off-Road Collisions
39 Percent of Fatal Crashes Involve Leaving the Roadway
Run-Off-Road (ROR) crashes involve vehicles that leave the travel lane and encroach onto the shoulder and beyond and hit one or more objects. Nearly 4 of every 10 fatal motor vehicle crashes—well over 14,000 a year—involve a single vehicle leaving the roadway. There are more than twice as many ROR fatal crashes on rural roads than on urban roads. Some 42 percent of ROR fatal crashes occur on curves (50 percent in rural areas). And the life-threatening events most likely to occur are rollovers (42 percent) and collisions with trees (25 percent).

This guide addresses reducing the likelihood that a vehicle will leave the roadway through roadway design, or if the vehicle does leave the road, then minimizing crashing or overturning; and if not, then by minimizing the severity of a crash.
