the

length of

the wheel

base (the distance from the front wheels to the rear

wheels) reduces the

likelihood the vehicle will tumble end over

drive

across an

incline,

the much more narrow

track width (the distance

betweentheleftandrightwheels)maynotpreventthevehiclefrom

tilting and rolling over.

Surface conditions can be a problem when you drive across a

hill.

Loose

gravel, muddy spots, or even wet grass can cause your tires

to slip
