According to the Los Angeles Times, the 4th of July holiday is the deadliest day for Los Angeles car accidents. AAA reports that teens account for approximately 10% of the traffic fatalities on Independence Day. Mothers Against Drunk Driving (MADD) cites that a drunk driver is involved in 39% of the car accident deaths on the 4th of July. This compares to 31% of car accident fatalities on other days.
The rise in drunk driving accidents on the 4th of July is partly due to the fact that schools and most businesses are closed, so there are more people on the road. This, combined with the many 4th of July parties around Los Angeles, often involving large amounts of alcohol, contributes to many Los Angeles car accidents.
It is also important to note that many police agencies around California will be setting up DUI checkpoints, to try to catch drunk drivers before they cause a Los Angeles car accident.
