Reducing Wrong-Way Driving Incidents on I-4

Wrong-way driving crashes occur when a driver has not observed posted traffic signs and proceeds in a lane going the wrong direction, increasing the risk of a head-on collision. To reduce wrong-way driving incidents, the Florida Department of Transportation (FDOT) is implementing Wrong-Way Vehicle Detection Systems (WWVDS) that help motorists properly identify interstate exit ramps to avoid entering the wrong-way.

Beginning September 2020, FDOT is increasing the amount of wrong-way signage, roadway reflectors and pavement markings on select State Highway System ramps in Central Florida. Each sign is equipped with radar to detect vehicles traveling the wrong way. Once triggered, lights begin to flash to notify the driver they are traveling in the wrong direction. If the motorist continues in the wrong way, radar detection sends alerts to FDOT’s District Five Regional Transportation Management Center (RTMC) and law enforcement. The RTMC systems also broadcast a wrong-way driver alert on electronic messaging boards along the interstate system to warn other motorists.

The first installation of WWVDS and other driving deterrents is part of the I-4 Beyond the Ultimate project. When completed, motorists can expect to see detection signs at eastbound and westbound exit ramps along Interstate 4 (I-4) in Orange, Seminole and Volusia counties.

This first batch of detection systems (known as Bundle A) will be at the following I-4 interchanges:

  1. Central Florida Parkway (EB exit only)
  2. Sand Lake Road (S.R. 482)
  3. Lake Mary Boulevard
  4. County Road 46A
  5. S.R. 46
  6. Orange Boulevard/U.S. 17-92
  7. Dirksen Drive
  8. Saxon Boulevard

To find out about construction in your area, sign up for advance construction alerts at I4Beyond.com/Alerts. For more information on the WWVDS, visit I4Beyond.com/wrongway.

Modifications or extensions to construction schedules may become necessary due to weather delays or other unforeseen conditions. Motorists are advised to maintain a safe speed when driving work zones. Additionally, Florida law requires motorists to put down cellphones and other handheld devices when driving through work zones.
