📄 Fatigue, Tiredness, and Driving: What You Need to Know

Fatigue and tiredness are serious risks for anyone behind the wheel. Driving while tired reduces concentration, slows reaction times, and increases the likelihood of accidents. Understanding the causes and warning signs can help you stay safe on the road. Common Causes of Driving Fatigue Lack of Sleep: Not getting enough rest is the most obvious cause of fatigue. Adults generally need 7–9 hours of sleep per night, and even slight deprivation can impair driving. Sleep Disorders: Conditions like sleep apnea, insomnia, or restless leg syndrome can prevent restorative sleep, leaving drivers tired even after a full night in bed. Long Driving Hours: Extended periods behind the wheel, especially on monotonous roads like highways or motorways, can make you drowsy. Time of Day: The body’s natural circadian rhythms make mid-afternoon and late-night driving particularly risky for fatigue. Alcohol or Medication: Even small amounts of alcohol or certain medications can intensify tiredness and impair your reaction times. Stress and Mental Fatigue: Emotional stress, overwork, or prolonged mental activity can also lead to tiredness that affects driving ability. Warning Signs You’re Too Tired to Drive Frequent yawning or blinking Difficulty keeping your head up Wandering thoughts or daydreaming Drifting across lanes or missing road signs Feeling irritable or restless behind the wheel Tips to Stay Alert While Driving Plan Rest Stops: Take a 15–20 minute break every 2 hours on long journeys. Get Enough Sleep: Prioritise a full night of sleep before long drives. Share Driving Duties: If possible, switch drivers to prevent fatigue. Avoid Heavy Meals: Large, heavy meals can make you drowsy. Stay Hydrated and Snack Smartly: Water and light snacks help maintain alertness. Caffeine Can Help—Temporarily: Coffee or tea can provide a short-term boost but don’t rely on it as a substitute for sleep. Driving while fatigued is just as dangerous as driving under the influence. Being aware of the causes, recognizing the warning signs, and taking proactive steps to stay alert can save lives. Always plan ahead, rest when needed, and never underestimate the impact of tiredness on your driving. ← Back to Resources
