SAN DIEGO (KGTV) - When it comes to wrong-way crashes in San Diego County, 2018 is off to an unfortunate start.

There have been numerous wrong-way vehicle crashes around the county nearly eight weeks into the new year, and authorities have not been able to pinpoint what exactly is causing an uptick in these types of crashes.

According to Caltrans data, from 1995-2012, an average of 23 people died each year in wrong-way crashes on California roadways.

San Diego had 13 wrong-way fatalities recorded in 2015 -- the last year Caltrans data was compiled for wrong-way crashes.

In 2017, Caltrans launched a two-year pilot program in San Diego and Sacramento that focuses on ways to not only prevent wrong-way crashes but to also alert authorities in the event a vehicle is traveling in the wrong direction.

As part of the test program, Caltrans has deployed reflective pavement markings on off-ramps and signs with flashing lights that turn on if a wrong-way vehicle is detected.

Caltrans has not yet provided data collected from the program to determine the protective measures' effectiveness.

Here's a look at wrong-way crashes on San Diego County roadways in the past 12 months.
