TOP TIPS TO HELP YOU RESTRAIN
YOUR LOAD EFFECTIVELY
Restraining your load is not complex, but it
does require training and knowledge
• Read this load restraint guide for light vehicles and keep it
handy as a reference
• Get training – from more experienced colleagues or load
restraint training organisations
Loads can and do move if not properly
restrained
• A load can move forwards, backwards or sideways and
must be restrained in each of these directions. You must
also ensure any upwards movement is limited.
• Light and heavy loads move just as easily – don’t assume a
heavy load will be held by its weight: it won’t
• Braking forces are typically higher at low speeds – don’t
assume because you are travelling slowly that you don’t
have to restrain your load correctly
Each load is different; consider the
restraint method that will work best
• Choose a load restraint method that allows you to meet
your legal obligations
• Choose a vehicle that meets the requirements for
dimension and projection, and is well-maintained and
roadworthy
• Choose load restraint equipment that is fit-for-purpose,
has the rated capacity to restrain the load and is in good
working order
There are two main load restraint methods
• Tie-down restraint – using lashings to clamp the load to
the vehicle (relying on friction for most of the restraint
forces)
• Direct restraint:
- Containing – the load is contained within the vehicle
- Blocking – the load is blocked from moving by a rigid
structure, e.g. a rated headboard
- Attaching – the load is attached to the vehicle
• A combination of the two methods can be effective
Check your loads and lashings regularly
during your journey to make sure the load
remains secure
• Lashings can lose tension during the journey and loads
may shift, settle or compress

PART A: PLAN FOR YOUR LOAD
Step 1: Understand your load
Think about the load that you plan to transport
What are the load’s characteristics:
- weight
- dimensions – length, width and height
- friction levels/texture – is it slippery or rough?
- centre of gravity of the load, or individual components
of the load – is it top heavy?
- stability – is it prone to roll or tip?
- vulnerability – is it fragile or crushable?
Step 2: Choose a suitable vehicle for

- Not being within the safe and legal maximum limits is
one of the most common reasons people are fined for
load breaches
Attach appropriate warning signals to the end of any
objects that project out from the back of the vehicle:
- During the day: a flag/material which is brightly
coloured and at least 300mm long.
- At night: a red light that can be seen from 200m away

PLAN FOR YOUR LOAD LIGHT VEHICLE GUIDE
PART B: LOADING THE VEHICLE
Step 5: Make sure you understand and
use safe work practices when loading and
unloading a vehicle
� Discuss who has authority over the loading process
before you begin
- The person who is loading the vehicle has authority
over the activity and directs the driver and anyone else
involved to make sure the activity is safe.
� Create loading and unloading plans
� Make sure everyone understands what to do
- Train new staff
� Create loading and unloading exclusion zones - higher
risk areas not to be entered during loading or unloading
� Stop work if people enter the loading and unloading
exclusion zones unexpectedly or without authorisation.
� Use an appropriate communication style for the
environment when loading/unloading
- For example, use hand signals in busy/loud areas –
don’t assume you can be heard
� Always maintain line of sight between the loader and the
driver
Step 6: Load the vehicle
� Make sure you use enough restraint to keep you and
others safe
� Every item must be restrained so that it can’t fall off
or move in a way that makes the vehicle unsafe or What makes a load

LOADING THE VEHICLE LIGHT VEHICLE GUIDE
LIGHT VEHICLE GUIDE
� Position your load to maintain vehicle stability, steering
and braking
� Keep the centre of gravity low and close to the
vehicle’s centre-line
- If you are using a containment method the centre
of gravity of the load must sit well under the top of
the tray (e.g. if an item is top-heavy, the heaviest part
must be contained within the tray and not sit above it)
� Spread the load evenly across the width and length
of the vehicle, sharing the weight between the axles Want to know more?

� Use packing material or rubber matting to increase
the friction on slippery loads – this makes them
easier to restrain – do not use conveyor belt rubber
� Stay within the safe and legal dimensions and projections
for your vehicle and load

LOADING THE VEHICLE LIGHT VEHICLE GUIDE
PART C: DRIVE ACCORDING TO THE
LOAD AND DRIVING CONDITIONS
Step 7: Allow for the impact of the load on
how your vehicle drives
� Monitor your vehicle’s stability, steering and braking
capacity
� Your load affects how your vehicle drives
� Drive carefully, take corners slowly and smoothly
and avoid harsh acceleration or braking wherever
possible
� Braking can be compromised if the load isn’t
distributed evenly and there is more weight on some
wheels than others
� There is potential for a greater braking force when
driving at low speed
� Be aware of how air pressure, e.g. wind and air
moving over the vehicle in motion, may affect your
load while driving
� Don’t drive an unsafe vehicle. Choose a better vehicle for
the load instead
Step 8: Check the load and its restraint
regularly during your journey
� Check your load and lashings regularly during your
journey to make sure the load remains secure
� Depending on the load and the restraint method,
you may need to check it soon after starting your
journey as the impact of driving will cause the load
to ‘settle’
� Recheck your load and lashings after you drop off part of
the load
� Check if the load has moved before unloading the load
