The Highway Patrol will have all available officers on duty this coming Labor Day weekend. The maximum enforcement period starts Friday evening at 6PM and will end at Midnight on Monday. The Labor Day enforcement period coincides with the nationwide "Drive Sober or Get Pulled Over" crackdown on drunk driving. The CHP says that last year over the Labor Day weekend, 49 people were killed in crashes across the state. The CHP also made more than 1,200 arrests for driving under the influence.
