LOS ANGELES—A total of 68 people were killed in crashes throughout California during the Independence Day maximum enforcement period, which began at 6:01 p.m. on June 30 and concluded at 11:59 p.m. on July 4, the California Highway Patrol (CHP) said July 6

Nearly half of the vehicle occupants who died within CHP jurisdiction were not wearing a seat belt.

The total numbers for Los Angeles County and Orange County were not immediately available.

Officers made 1,224 arrests for driving under the influence and issued 9,700 citations for speeding, according to the highway patrol.

“The results of this [maximum enforcement period] are concerning and reinforce the need for responsible behavior behind the wheel,” said CHP Commissioner Sean Duryee. “All of these deaths were preventable, and the loved ones they leave behind will be forever impacted.”

The next maximum enforcement period was scheduled for Labor Day weekend.
