[KOH] NDOT will begin installing wrong-way driver detection systems this week in Carson City on Interstate 580. Shoulders will be intermittently closed through late August. Some ramps will be closed at night between 8 p.m. to 5 a.m. weekdays the last two weeks of August.

The systems use radar and closed-circuit cameras to automatically detect vehicles entering in the wrong direction, activating two sets of red flashing wrong-way signs on the ramp. Between 2014 and 2018, there were an average of 27 crashes and over 90 citations per year associated with wrong-way crashes in Nevada.

NDOT recently studied 37 wrong-way driver detection systems in the state. The study showed that 84% of wrong-way vehicles detected safely turned around before entering the freeway.
