A Las Vegas trucker and driving school have come forward with tips on how to avoid drowsy driving following a serious crash involving a sleepy truck driver on Highway 93 recently.

Police say that the crash that killed two and injured three after a semi truck crashed into several vehicles was possibly caused by a drowsy truck driver, and are now searching for answers to two questions: What do drivers do to stay alert while driving on the road? And how are driving schools preparing them so that they can avoid these kinds of crashes?

“He should have pulled over hours and hours ago, or not be out, I mean me myself, if I’m not getting six to eight hours of sleep, I don’t feel comfortable behind a wheel, so I make sure I always get enough rest,” said truck driver Rudy Hegsted to Las Vegas Now News.

“Coffee, energy drinks, they just make you tired, you just got to pull over, take a nap and move on,” he continued.

Truck driving school in the Las Vegas area also claim to take steps towards educating future truck drivers on the dangers of drowsy driving.

“The industry does allow for us to drive 11 hours a day max, and then after 11 hours a day we have to shut down and have 10 hours of sleep,” said Daniel Rios, the director of education at DTR School of Trucking, who also mentioned the required 30 minute break in the first eight hours of drive time.

Rios says that the DTR School of Trucking teacher their students how to make driving plans as a way to avoid fatigue while operating the big rig.

“It does give you more stamina to keep going, and you’re more alert,” said Rio.

“Because when you’re not alert, you know, you can’t make good decisions.”

“Once your eyes start closing, you’ve got to pull over and take a nap, that’s just all there is to it,” Hegsted added.

According to The National Highway Traffic Safety Administration, drowsy driving kills up to 8,000 people a year and causes around 1.2 million crashes a year.
