Driving while fatigued, especially at night, is as deadly as driving under the influence of alcohol. Fatigue reduces your reaction time, judgment, and mental alertness. If you drive this way for too long, then falling asleep at the wheel is sure to follow. It can happen to anyone because no drug is required for this type of impairment. Unlike DUI driving, the antidote for fatigued driving is easy and quick: drinking a cup of coffee while taking a rest break. However, coffee has its limitations. It won’t work for severe.
