slowly,
Bui cl you should ever have a "blowout", here are
a few lips atwut what lo axpeet and whal to do:
If a front lire fails, the flat tire will create a drag lhal
pulls the vehicle toward that side. Take your fMt off ihe
accelerator pedal and grip the sleering wheel firmly.
Bleer fo rnamtain lane position, and then gently brake to
a slop well ONl of Ihe traltic lane.
A rear blowout, particularly on a curva, acts much like a
skid and may require the same correction you'd
use
in a skid, In any rear blowouh remove your foot rrom the
accelerator pedal. Get the vehicle under coniroi by
steering Ihe way you want ihe vehicle to go. If may be
very bumpy and noisy, t)ul you can slill sieer. Geniiy
braka to a stop — well off
the road if possibla.
