Warning Signs of Fatigue According to the National Sleep Foundation’s Sleep in America poll, 60% of Americans have driven while feeling sleepy and 36% admit to actually having fallen asleep at the wheel in the past year. However, many people cannot tell if or when they are about to fall asleep. Here are some signs that should tell you to stop and rest Difficulty focusing, frequent blinking or heavy eyelids Yawning repeatedly or rubbing eyes Daydreaming or wandering/disconnected thoughts Trouble remembering the last few miles driven missing exits or traffic signs Trouble keeping head up Drifting from your lane, following too closely or hitting a shoulder rumble strip Feeling restless and irritable When you are tired trying to push on is far more dangerous than most drivers think. It is a major cause of fatal accidents. If you notice any signs of fatigue, stop driving and go to sleep for the night or take a 15 – 20 minute nap.
