Driving Information
Driver Behavior
Driving is an important
responsibility. Driver behavior, the
driving environment, and the
vehicle's design all affect how well a
vehicle performs.
Being aware of these factors can
help in understanding how the
vehicle handles and what can be
done to avoid many types of
crashes, including a rollover crash.
Most serious injuries and fatalities to
unbelted occupants can be reduced
or prevented by the use of seat
belts. In a rollover crash, an
unbelted person is significantly
more likely to die than a person
wearing a seat belt. In addition,
avoiding excessive speed, sudden
or abrupt turns, and drunken or
aggressive driving can help make
trips safer and avoid the possibility
of a crash.
