as far forward and as low as
possible. The heaviest things
should be on the floor,

making it more likely to roll
over. You can be seriously or
fatally injured if the vehicle
rolls over. Put heavy loads
inside the cargo area, not on
the roof.

the vehicle, see Vehicle Load Limits
and Tires.

roads, and areas that have been
set aside for public off-road
recreational driving and obey all
posted regulations.
