Microsleep while driving.

A brief attention lapse at road speed can cover a large distance without an effective response. If you notice head nods, long blinks, lane drift, or missing memories from the road, stop treating the drive as manageable.

Act immediately

Pull over at a safe, legal place. Change drivers, rest, or arrange another way to travel. Do not use EyeJolt, caffeine, music, or an open window as permission to continue.

Why people miss it

Microsleeps can occur without awareness. Drivers are also poor judges of how much fatigue has degraded their performance.

Technology is secondary

Vehicle driver-monitoring systems and consumer apps may provide warnings, but they cannot restore sleep or guarantee detection. Built-in vehicle systems should be used as the manufacturer directs.

Plan before departure

Start rested, check medicines for drowsiness warnings, avoid alcohol, and reconsider travel during your personal high-sleepiness periods.
