BAKERSFIELD, Calif. (KGET) — The California Highway Patrol is reminding motorists to drive the speed limit and deploying extra officers to look out for distracted or impaired drivers over the Fourth of July holiday.

Last year, the CHP arrested 997 people statewide for driving while impaired during the agency’s 78-hour maximum-enforcement period, according to a release. Nearly 10,000 citations were issued for speeding.

Extra officers will be patrolling starting Friday evening through Monday.

CHP Commissioner Amanda Ray tweeted on Sunday, officers had already made over 600 arrests for impaired driving during the first 30 hours of the enforcement period.
