BAKERSFIELD, Calif. (KGET) -- 119 million Americans are expected to take to the skies or hit the road for holiday travel in the coming days. Navigating safely through Kern County roads during the dangerous fog can be a challenge without the right precautions. 8.7 million people will be hitting the roads in Southern California during Christmas, and it's going to take more than Rudolph to help you navigate safely because visibility greatly lowers in the seasonal fog. "Your visibility can go from let's say a half a mile to barely anything really quick," said California Highway Patrol officer DC Williams. CHP officers already answered the call of a crash involving an amazon truck and a school bus Dec. 20 on 7th Standard Road. No injuries are reported, but not everyone is so lucky. Dense fog played a major factor in this deadly 35 car pile up on I-5 west of Bakersfield, during the first week of January in 2023. Two people were killed, and nine others injured.

The tule fog has returned to Kern County, named after the tule grass making up the wetlands of the Central Valley. "Slow down. Watch your lane changes. Make sure things are clear," said Williams. "Make sure you've got your lights on." Pack a go bag with water, blankets, food and flares, but most importantly, pack your patience. "The majority of the crash reports that I review are from people driving too fast," Williams said. Give yourself 5 seconds of distance from the vehicle in front of you and use your flashers. Williams says never drive on the shoulder because you could crash and become the traffic obstacle. "Say you hit somebody and all your lights go out. Now, that's a danger not only for yourself, but for people who are coming up," said Williams. The driver is in control so, keep your eyes on the road. Eliminate distractions including loud music, shouting and put the phone screen down. "Let's say you run that red light, or you're passing on the shoulder, or you're driving too fast and you cause a wreck and say you're okay," said Williams. "Well there's that family you hurt...there's somebody who didn't make it and you've got to live with that."
