DOT Core · Driver Training VideoFatigue Management

And here's what makes it dangerous in this job: fatigue lies to you. The last person to know you're falling asleep is you. So don't listen to how you feel — watch for the signs: you can't remember the last two miles. You're drifting on the lane line and correcting late.

The microsleep is the killer: three to five seconds where your eyes are open and nobody's home. At highway speed that's four hundred feet of unmanned truck. Most fatigue crashes are a drift — no brake lights, no swerve — because the driver wasn't there for it.

What actually works: sleep

Seven to eight hours, protected like your license depends on it, because it does. Dark cab — blackout curtains, cold air, phone silenced. The legal ten-hour break only helps if there's real sleep inside it.

What doesn't work: coffee buys you thirty minutes, then sells you back worse. Loud music, open windows, slapping your face — those are signs to pull over, not solutions. The only fix for sleepiness is sleep.

Know your danger windows: two to six in the morning, and two to four in the afternoon — the body dips on its own clock, whatever your log says. Plan your hardest miles outside them when you can.

Your company standard: too tired to drive means park — that phone call will never be punished here. Protect your ten hours; family and dispatch both learn your sleep window. Nap early when the signs start, not after the drift.
