Disorders such as chronic insomnia, sleep apnea and narcolepsy, all of which lead to excessive daytime sleepiness, afflict an estimated 30 million Americans. Most people with sleep disorders remain undiagnosed and untreated. The disorder is associated with a three to seven time increase in crash risk. While this varies from individual to individual, the average person requires about 8 hours of sleep a night. Plan to drive long trips with a companion.
Passengers can help look for early warning signs of fatigue or switch drivers when needed.
Passengers should stay awake to talk to the driver. Schedule regular stops, every 100 miles or 2 hours. Respond to symptoms of fatigue by finding a safe place to stop for a break. Drink coffee or another source of caffeine to promote short-term alertness if needed. Motorists should be warned that if they cross over a rumble strip, they may be tired and should get off the road to rest.
