Wrong Way Crash Avoidance

While incidents resulting from wrong-way driving make up a small percentage of the overall crashes that take place on our highways, they are far more likely to result in fatalities. We are working aggressively to add safety features to reduce the occurrence of wrong-day driving.

Nationally, about 360 people die each year in one of these crashes. Here in Rhode Island, we have witnessed 10 fatal crashes, resulting 13 deaths since 2008. Alcohol impairment is a leading factor for wrong-way crashes, and most happen on weekends and during evening and overnight hours.

What we are doing

In 2015 we completed a $2 million project to upgrade the signing and striping at 145 locations (more than 200 actual ramps) and install detection systems at 24 high-risk areas. These systems not only alert a driver who traveling in the wrong direction, they notify police and other motorists of a potential wrong-way driver.

All of Rhode Island's limited access highways were targeted for improved signage and pavement markings to clearly distinguish exit ramps from entrance ramps and prevent confusion. At the two dozen high-risk areas, most in the Providence metropolitan area, new detection systems sense if a driver has entered a highway off-ramp, and activate a series of flashing signs. It will also notify the Rhode Island State Police that someone is driving the wrong way on the road, take a picture of the vehicle, and display a message on our overhead signs to warn drivers heading in the opposite direction.

Our plan is modeled on a similar project in San Antonio, Texas, where 29 flashing signs were installed along a major highway. Within a year, there was a 30 percent reduction in wrong-way driving incidents.

Wrong Way Driver Detectors

This interactive map shows the locations where we installed wrong-way driver detectors, which will alert police and other motorists if someone gets on a highway in the wrong direction.
