LEGISLATION
LICENCE
A vehicle towing a trailer forms a combination of vehicles. In order to drive a combination
of vehicles, it is necessary to understand and comply with the relevant legislation in the
Highway Code:
French driving licence for driving a combination of vehicles in France:
- If the PTAC does not exceed 750Kg, the driving licence category B is sufficient
- Since 19/01/2013, if the PTAC exceeds 750Kg, the driving licence category B is
sufficient if the total PTAC of the towing vehicle and the trailer is equal to or inferior to the
3500Kg
If one of these conditions is not met, not only is the driving licence category B required,
but also:
- a 7h training course to drive a combination of vehicles whose PTAC is between
3500Kg and 4250Kg
In any case, the sumof the total laden weightsmust not exceed the PTRA of the towing vehicle.
For more information, contact the official organizations concerned.
INSURANCE
A trailer that has a PTAC that does not exceed 500Kg is generally covered by the towing
vehicle’s insurance. However, it is advisable to contact your insurer.
Above 500Kg of PTAC, it must have its own individual insurance.
(Ask your insurer about that)

REGISTRATION
A trailer that exceeds 500Kg of PTAC must have its own number plate and registration
document.
Below 500Kg of PTAC, it is sufficient to attach a homologated number plate bearing the
towing vehicles registration number.

DIRECTIONS FOR USE
It is essential that the trailer is loaded correctly in order for it to be towed and used on the public
highway safely. 3 critical factors must be respected: The laden weight, the position of the load,
the way in which the load is secured.
You are entirely responsible for securing the load that you are transporting.
Reminder:
1m3of sand weighs approximately ±1800Kg.
1m3of wood weighs approximately 450/650Kg (depending on the level of dryness).
COMPLIANCE WITH THE LOAD CAPACITY
The load capacity of the trailer is the difference between it’s unladen weight shown on the plate
as the tare and its PTAC. Remember to take the weight of any accessories into account as
they will reduce the load capacity.
LOAD POSITIONNING
Every precaution must be taken to ensure that the load transported bya vehicle or trailer cannot
cause damage or danger (Article R312-19 Highway Code)
The load must be positioned in such a way that the weight at the ball hitch is equal to
approximately 5 to 10% of the total mass of the trailer and its load, without, however,
exceeding the maximum weight indicated on the manufacturer’s plate shown opposite the
figure 0, which is a legal requirement. (Refer to the image shown below).

The position of the load on the trailer is extremely important. If it is too far forwards, there will
be too much weight on the ball hitch and there is a risk that the draw bar will break. Too
much at the back, there is a risk of the trailer having uncontrollable yaw, and therefore a very
high accident risk.
The trailers made by COCHET SA. Comply with the legislation n°55 and are designed to have
a hitch height of between 395mm and 465mm.
STRAPPING DOWN THE LOAD
The load to be transported must be strapped down tightly to avoid any movement in the event
of an emergency stop. Correct strapping will also prevent the load from moving and as a result,
any movement away from the centre of the trailer, therefore eliminating the risk of trailer yaw.
In order to strap the load correctly, use the rings provided. You can also use the bars on the
trailer sides if the trailer is fitted with them, or you can hook the straps directly onto the trailer’s
chassis.

HITCHING AND UNHITCHING
When using the trailer for the first time, ask your dealer to show you how to
hitch the trailer correctly.
Warning ! Before coupling and
uncoupling, make sure that the
wheel is in the stowed position.
HITCHING
1) This manoeuvre is extremely important. Check that your
ball hitch has the handle in the locked position (raised), and
that the red guide is visible.
2) Move the ball hitch to within a few centimetres of the
towing ball. Use the jockey wheel to simplify this manoeuvre.
