Most of us would like to think we'd pull over if we were too tired. But the symptoms of being too tired are difficult to notice, particularly when sleep deprived. We react to sleep deprivation long before we actually fall asleep at the wheel. If you experience difficulty focusing, frequent blinking or heavy eyelids, daydreaming, drifting from your lane, repeated yawning, trouble keeping your head up or trouble remembering the last few miles driven - it's time to pull over.
Sleepiness, like alcohol, slows reaction time, impairs judgment, and decreases awareness, which significantly increases the risk of a crash.
