As May brings an increase in celebrations and holiday travel periods, authorities in cities such as Chula Vista and across San Diego County are stepping up enforcement operations targeting drivers under the influence of alcohol and drugs.

The Chula Vista Police Department announced that it will conduct a DUI checkpoint this Friday, May 15, at an undisclosed location within the city.

According to a statement released by the department, the checkpoint will operate from 6:00 p.m. to midnight and was selected “based on data showing incidents of impaired driving-related crashes.”

“The primary purpose of DUI checkpoints is to promote public safety by taking suspected impaired drivers off the road,” local police stated.

Authorities noted that May is often considered a higher-risk period for traffic incidents due to the increase in social gatherings and travel across Southern California, especially ahead of Memorial Day, which marks the unofficial start of summer.

“Impaired drivers put others on the road at significant risk,” Agent Brian Carter said. “Any prevention measures that reduce the number of impaired drivers on our roads significantly improve traffic safety.”

Police also reminded the public that impaired driving is not limited to alcohol consumption. Some prescription medications and over-the-counter drugs may interfere with a person’s ability to drive safely. In addition, while medicinal and recreational marijuana are legal in California, driving under the influence of marijuana remains illegal.

According to data cited in the statement, a first-time DUI conviction can result in average costs of approximately $13,500 in fines, legal penalties, and license suspension.

In South County border communities such as Chula Vista and San Ysidro, these types of enforcement operations often draw attention from residents because of the heavy traffic flow and proximity to the border.

On social media and in community spaces, some residents have expressed concern about possible confusion between traffic checkpoints and immigration enforcement operations. However, in California, DUI checkpoints must comply with specific legal guidelines, including prior public notification. The program is funded through a grant from the California Office of Traffic Safety via the National Highway Traffic Safety Administration.
