California Department of Transportation’s Wrong Way Driving Countermeasures

Following a surge in wrong-way crashes – including a high-profile incident in 2021 – the District 11 (San Diego) team within the California Department of Transportation initiated an emergency contract, followed by two major contracts, to implement wrong way countermeasures. The $6 million project also included a comprehensive campaign to raise awareness and educate the public. Prior to this initiative, Caltrans District 11 piloted effective wrong-way countermeasures, reducing reported incidents by over 60%. These measures were adopted as a statewide standard, enhancing transportation safety across California. The project upgraded exit ramp markings and installed effective wrong way driving countermeasures, aiming to eliminate fatal and serious injuries. Those measures have significantly reduced wrong way driving incidents, reversing the upward trend of crashes and fatalities. Caltrans remains committed to ensuring safe roadways for all communities, continuously monitoring and enhancing safety measures.
