Further safe-riding points
Be sure to signal clearly when
making turns.
Braking can be extremely difficult
on a wet road. Avoid hard bra-
king, because the scooter could
slide. Apply the brakes slowly
when stopping on a wet surface.
Slow down as you approach a
corner or turn. Once you have
completed a turn, accelerate
slowly.
Be careful when passing parked
cars. A driver might not see you
and open a door in your path.
Railroad crossings, streetcar
rails, iron plates on road cons-
truction sites, and manhole
covers become extremely slip-
pery when wet. Slow down and
cross them with caution. Keep
the scooter upright, otherwise it
could slide out from under you.
The brake pads could get wet
when you wash the scooter. After
washing the scooter, check the
brakes before riding.
Always wear a helmet, gloves,
trousers (tapered around the cuff
and ankle so they do not flap),
and a bright colored jacket.
Do not carry too much luggage
on the scooter. An overloaded
scooter is unstable. Use a strong
cord to secure any luggage to the
carrier (if equipped). A loose load
will affect the stability of the sco-
oter and could divert your atten-
tion from the road. (See page
1-1).
