R Secu rethe load on the trailer in line with the
re qu irements and rules for load-securing

R When driving with a trailer, check at regular
inter vals that the load is secure and that the
lights and brakes are functioning cor rectl y.
R Bear in mind that the handling characteristics
are more uns table when towing a trailer than
when driving without a trailer. Avoid sudden
st eering mo vements.
R The vehicle/trailer combination is heavier,
accelerates more slowl y,has a reduced
climbing ability and an increased braking dis‐
