Buick 1993 Roadmaster Owner's Manual page 173

An emergency like this requires close attention and a
quick decision.
If
you are holding the steering wheel at
the recommended 9 and 3 o'clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have to act fast, steer quickly, and
just as quickly straighten the wheel once you have
avoided the object.
You
must then be prepared to steer
back to y.our original lane and then brake to a controlled
stop.
Depending on your speed, this can be rather violent for
an unprepared driver. This is one of the reasons driving
experts recommend that you use your safety belts and
keep both hands on the steering wheel.
The fact that such emergency situations are .always
possible is a good reason to practice defensive driving at
all times.
