Driver Fatigue
Just about everyone has experienced feelings of grogginess while driving, performing monotonous tasks or operating machinery. However, actualdriver fatigue, also known as drowsy driving, is a physiological and psychological condition that can greatly affect driving judgment and abilities. Driver fatigue not only impacts alertness and response time but also increases the chances of being involved in car accidents.
Driver Fatigue Symptoms
- An overall sleepy, groggy or exhausted feeling
- Frequent yawning
- Irritability
- Concentration difficulties
- Eyes may feel strained, sore and tired
- Poor steering – less effectively or with too much action
- May miss road signs and ignore lanes
- May experience short bursts of microsleep (a lapse from wake to sleep that lasts only a few seconds)
Warning Signs of Driver Fatigue
One of the ironies of drowsy driving is that the driver may be too tired to determine his or her own level of fatigue. The problem, therefore, is often ignored. Here are some warning signs of driver fatigue:
- Daydreaming while on the road
- Driving over the center line
- Excessive yawning
- Feeling impatient
- Feeling stiff heavy eyes
- Reacting slowly
There are certain times of the day and night when our energy levels naturally dip. These circadian rhythms are part of a normal sleep/wake cycle. In reaction to these dips, between 10:00 p.m. and 6:00 a.m. and 1:00 p.m. and 4:00 p.m., drivers are more at risk for experiencing driver fatigue.
Driver Fatigue Management Tips
Effective driver fatigue management is essential. Here are some tips you can use to make sure you get where you need to go safely.
- Get sufficient rest (8 – 9 hours of sleep) prior to driving.
- Avoid alcohol, large meals and any medications that might make you drowsy.
- Establish a realistic driving plan, one that does not require driving long periods without a good night's sleep and healthy breaks.
- Remember to stay hydrated, get lots of fresh air and incorporate environmental stimuli when possible (music, conversation, etc.).
- Share the driving whenever possible and really try to rest when it isn't your turn to drive.
- When driving, take a break at least every two hours. During these breaks, nap, eat a snack or drink an energy beverage.
