Don't Use Cruise
Control when Driving in the Rain-Truth!
Summary of the eRumor A warning from a driver
who lost control of his or her car during slippery conditions and
was told by a law officer that cruise control should never be used
when it is raining.
We checked with the departments of
transportation for Minnesota, Wisconsin, and Washington State as
well as visiting several websites of other states and the consensus
is clear: Don't use cruise control during winter conditions
such as when it is snowing or icy or under other slippery conditions
such as when it is raining.
The comments and warnings we found were:
...The cruise control is designed for normal road conditions.
It doesn't know when the pavement is slippery. Under slick
conditions, you need to be in complete control and monitoring road
conditions. You're more likely to notice hydroplaning if you
are not relying on the cruise control.
...With some cars, it is possible that the wheels will actually spin
faster when the cruise control is on and the car hits a slippery
spot. When the tires make contact with firm road again, the
car can skid or lose control.
...On most cars, the cruise control is disengaged by tapping on the
brake. In an emergency, this adds a fraction of a second to
your response time as well as the risk of the braking action itself
causing a loss of control on a slippery road.
A real example of the eRumor as it has
appeared on the Internet:
I learned a lesson I'd like to pass on to you. You may
know this already- but the highway patrolman told me that you should
never drive in the rain with your cruise control on. He said if you did
and hydroplaned (which I did) that when your tires were off the road
your car would accelerate to a high rate of speed (which it did). You
don't have much, if any control when you hydroplane, but you are totally
in the hands of God when the car accelerates. I took off like I was in
an airplane. I'm so thankful I made it through that ordeal. Please pass
the word around about not using cruise control when the pavement is wet
or icy. The highway patrolman said this should be on the sun-visor with
the warning about air-bags.
The only person I've found out who knew this (besides
the patrolman) was a man who had a similar accident and totaled his car.
This has made me wonder if this is not why so many of our young people
are dying in accidents."
