9.24.1 Ways of preventing a vehicle becoming overloaded:

Know the weights of your vehicle and load. If possible, weigh the vehicle to
establish individual axle weights.
Re-Distribute your load appropriately after any drop-offs to avoid overloading
axles.
Check the Gross Vehicle Weight before setting out, either using your own weighbridge,
or one nearby. You are allowed to drive to the nearest available weighbridge to check
your load if found to be overloaded please report to the Transport Manager who will advise
a solution.
Do not automatically trust declared weights, invoices or delivery notes given
to you by customers. Remember that you hold the responsibility for not overloading,
not the customer.
Remember that the GVW and GTW include the weight of the vehicle, load, trailer
(for GTW) driver and any passengers. Also allow for the weights of any pallets or
packing cases.
Make sure that your lift / tag axle is used correctly (where fitted). Not using this
axle when the vehicle is loaded means that axles or gross weights could exceed their
allowed limits.

9.24.2 The effects of overloading a vehicle:

It makes the vehicle less stable, difficult to steer and take longer to stop. Vehicles react
differently when the maximum weights which they are designed to carry are exceeded.
The consequences can be fatal.

Massive strain is put on vehicle tyres. Overloading can cause the tyres to overheat and
wear rapidly which increases the chance of premature, dangerous and expensive failure
(such as blow outs).

Insurance cover is void. Overloading a vehicle is illegal and therefore insurance cover
can be voided if the vehicle is involved in a road traffic incident.

It causes excessive wear and damage to roads, bridges and pavements at the expense
of the taxpayer.

It is unfair on other operators. Exceeding weight limits is unfair competition as more load
is moved per journey.

Fuel consumption increases when carrying extra load, which will increase your costs.

There is also an effect to the business where a PG9 will be issued and this will affect the
company Operator Compliance Risk Score (OCRS)

What else to look out for: MAM (Maximum Authorised Mass)

Maximum authorised mass (MAM) means the weight of a vehicle or trailer including the
maximum load that can be carried safely when it’s being used on the road.
This is also known as gross vehicle weight (GVW) or permissible maximum weight.
It will be listed in the owner’s manual and is normally shown on a plate or sticker fitted to the
vehicle.
The plate or sticker may also show a gross train weight (GTW), also sometimes called gross
combination weight (GCW). This is the total weight of the tractor unit plus trailer plus load.
