366 Driving and Operating
Trailer Brakes
Loaded trailers over 450 kg
(1,000 lb) must be equipped
with brake systems and with
brakes for each axle. Trailer
braking equipment conforming
to Canadian Standards
Association (CSA) requirement
CAN3-D313, or its equivalent,
is recommended.
State or local regulations may
require trailers to have their
own braking system if the
loaded weight of the trailer
exceeds certain minimums
that can vary from state to
state. Read and follow the
instructions for the trailer
brakes so they are installed,
adjusted, and maintained
properly. Never attempt to tap
into your vehicle's hydraulic
brake system. If you do, both
the vehicle anti-lock brakes
and the trailer brakes may not
function, which could result in
a crash.
Trailer Lamps
Always check all trailer lamps
are working at the beginning
of each trip, and periodically
on longer trips.
Turn Signals When
Towing a Trailer
When properly connected, the
trailer turn signals will
illuminate to indicate the
vehicle is turning, changing
lanes, or stopping. When
towing a trailer, the arrows on
the instrument cluster will
illuminate even if the trailer is
not properly connected or the
bulbs are burned out.
