Using trailer brakes
Use electric brakes or manual,
automatic or surge type hydraulic
brakes that meet Federal and local
regulations. Install and adjust
brakes according to the
manufacturer's instructions.
Do not connect a trailer's
hydraulic brake system
directly to your vehicle's brake
system. Your vehicle may not have
enough braking power and your
chances of having a collision
greatly increase.
Using safety chains
Always connect the trailer's safety
chains to the vehicle. To connect
the chains, cross the chains under
the trailer tongue and attach to the
vehicle frame or hook retainers
(not the bumper). Make sure there
is enough slack to allow the vehicle
to turn corners.
