Highway Hypnosis; Hill And Mountain Roads - GMC Envoy Owner's Manual

Highway Hypnosis

Is there actually such a condition as highway hypnosis?
Or is it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch of road with the
same scenery, along with the hum of the tires on the
road, the drone of the engine, and the rush of the wind
against the vehicle that can make you sleepy. Do not
let it happen to you! If it does, your vehicle can leave the
road in less than a second, and you could crash and
be injured.
What can you do about highway hypnosis? First, be
aware that it can happen.
Then here are some tips:
•
Make sure your vehicle is well ventilated, with a
comfortably cool interior.
•
Keep your eyes moving. Scan the road ahead and
to the sides. Check your mirrors and your
instruments frequently.
•
If you get sleepy, pull off the road into a rest,
service, or parking area and take a nap, get some
exercise, or both. For safety, treat drowsiness
on the highway as an emergency.

Hill and Mountain Roads

Driving on steep hills or mountains is different from
driving in flat or rolling terrain.
