Driver
Fatigue During Holiday Travel
The holiday
season is a time when people are doing a lot of highway driving
and one thing to be aware of is driver fatigue. It is one of the
most unnerving experiences in driving. You've been on the road
awhile. The highway seems endless-long, smooth, monotonous. The
car interior is warm. You're tired, the radio isn't holding your
attention, and neither is the driving. You stare straight ahead
at miles and miles of road as you start to feel your shoulders
sag and your eyes slowly
start
close.
Abruptly,
you open your eyes and jerk up in your seat. You've started to
drift out of your lane, or maybe even off the road but steer your
car back into the lane, take a few deep breathes and realize fearfully
what just happened. You were asleep.
Fatigue on
the road can be a killer. It happens frequently on long rides
especially long night drives. You may have recognized some warning
signs of fatigue in the foregoing scenario. Other signs of fatigue
include back tension, burning eyes, shallow breathing, inattentiveness
and any kind of erratic driving such as drifting, abnormal speed,
tailgating, or failure to obey traffic signs.
One cause
of fatigue is alcohol consumption. Alcohol is a depressant and
a driver doesn't have to be drunk to fall asleep at the wheel.
Even one drink can be enough to induce fatigue.
Another culprit
is the nature of modern highway driving. Most car interiors have
comfortable cushioned seats, in quiet carpeted temperature-regulated
environments. Many vehicles have cruise control. Most major roads
have been engineered to eliminate sharp curves, hills and bumps.
Ironically these designs for comfort contribute to falling asleep
at the wheel.
Additionally,
dull landscapes, the droning of tires and engines, and the repetitive
patterns of oncoming headlights, trees, poles, and highway center
lines can lead to a dangerous trance-like state known as "highway
hypnosis," which deadens drivers' senses and slows their
reaction time.
Fatigue behind
the wheel is a very real danger, even if you've never experienced
it firsthand. The National Safety Council offers these tips for
staying awake while you're driving.
- An obvious
cause of fatigue is lack of sleep. If you haven't received seven
or eight hours of sleep the night before a trip, you are courting
with fatigue. Get enough rest and don't start a trip late in the
day. Long distance driving is hard work and you need to be fresh
and alert.
- If possible,
don't ride alone, passengers can take turns driving and also serve
as conversation partners to keep you awake.
- Avoiding
rides at night. The glare of lights both on your dashboard and
outside your car increases the danger of highway hypnosis.
- Adjust your
car's environment so that it helps keep you awake and alert. Keep
the temperature cool, the radio volume up and switch stations
frequently but avoid soft music, do not use cruise control, feel
your body involved with the driving.
- Watch your
posture, drive with your head up and your shoulders back, tuck
your buttocks against the seat back, legs should not be fully
extended but level at about a 45-degree angle.
- Take frequent
breaks, at least every two hours, stop at a gas station, restaurant
or rest stop, get out of the car, walk around, even jog or do
calisthenics. Exercise fights fatigue.
- In addition
to the exercise breaks, stop for light meals and snacks. Avoid
alcohol entirely.
- Don't allow
your eyes to become fatigued or hypnotized, wear sunglasses to
block glare (but never wear sunglasses at night).
- If anti-fatigue
measures fail and you start noticing the danger signs of fatigue,
then there is only one solution. Sleep. Find a safe, guarded rest
area, truck stop, or service station. Even a 20-minute nap may
refresh you enough to get to a hotel or motel. (This is an emergency
maneuver. Do not try it as a common driving technique).
Safe driving
demands your full attention. If you feel your eyelids getting
heavy, then your next actions may not simply determine whether
you'll stay awake. They might determine whether you'll stay alive.
