3.6 DRIVING
3.6.1 DRIVING LICENCE
Esure you have suitable driving licence
entitlements for the vehicle/trailer combination.
3.6.2 TOWING SPEED
Always comply with the driving speed
regulations that apply in the country in
which you are towing. Ifor Williams Trailers
recommends that when towing horses, you
restrict your speed to 55mph/85km - even
if local regulations permit towing at a
higher speed.
NOTE: The 60mph limit is allowed on
motorways and unrestricted dual carriageways
only. On other unrestricted roads the limit is
50mph. If your vehicle & trailer combination
is over 7500kg combined MAM speeds
are further restricted to 50mph on dual
carriageways and 40mph on other roads.
3.6.3 STABILITY
All our trailer models are of a well-balanced
design and should be exceptionally good
towers.
All Ifor Williams Trailers are designed and
thoroughly tested to ensure safe and stable
towing. If poor stability when towing is
experienced, then possible causes include:
1. Worn springs or loose suspension fixings
on the towing vehicle.
2. Towing vehicle springs too soft.
3. Insufficient nose weight.
4.
Nose of the trailer either too high or too
low, due to incorrect height of the tow ball.
5. Insufficient tyre pressures, towing vehicle
and trailer.
6. Unsuitable towing vehicle.
3.6.4 SNAKING
This is a term used to denote an unstable
towing vehicle and trailer combination where
the trailer ‘weaves’ from side to side often
causing a similar swaying movement in the
towing vehicle itself.
CAUSES:
1.
Insufficient nose weight.
2. Incorrect vehicle tow ball height.
3. Incorrect loading or weight distribution.
4.
Insufficient tyre pressures, tow vehicle
and trailer.
5. Excessive speed, especially
downhill.
6. Erratic driving.
7. Being overtaken by a large fast-moving
vehicle.
8. Overtaking.
9. Side winds.
10. Unsuitable or unbalanced trailer.
ON THE ROAD
If you do find your outfit snaking, try to keep
the steering wheel in a central position as
far as possible, decelerate and avoid braking
if possible.
3.6.5 STABILISERS
A stabiliser should never be used to try to
improve a trailer/towing vehicle combination
that has poor stability as instability may
occur at higher speed.
However, a good stabiliser can make an
acceptable trailer/towing vehicle combination
more comfortable and easier to handle.
