Carry out HGV daily walkaround checks

What you need to check inside and outside of the vehicle when you do a lorry or other HGV walkaround check.

Applies to England, Scotland and Wales

You’re responsible for making sure your vehicle is safe to drive.

Carry out a walkaround check of the vehicle before your journey to make sure it’s safe. Report any defects in writing to the person in charge of sorting out vehicle defects in your organisation.

The police and Driver and Vehicle Standards Agency (DVSA) officers can stop you to do checks on your vehicles.

You can be stopped from driving until you fix any problems they find, or they can issue you with a fine.

If you’re a transport manager or vehicle operator, read guidance about how to make walkaround checks part of your processes for keeping your vehicles safe to drive.

Watch a video showing what checks to do

This short video shows some of the checks that you should do. Read the full list in this guide for more details.

Check inside the vehicle

1. Front view (mirrors, cameras, and glass)

Check that no objects get in the way of your front view.

As a general rule, there should be nothing in the swept area of the windscreen wipers.

  • cracked
  • scratched
  • discoloured

Check that the windscreen and front side windows are not excessively tinted.

Check that all mirrors are in place and not:

  • insecure

If a camera system is used instead of a mirror, check that it works and the view is correct.

2. Windscreen wipers and washers

Make sure the windscreen wipers work. Check that they are not:

  • missing
  • damaged or worn

Make sure the windscreen washer is working.

  • there are no air leaks
  • the footwell is clear
  • the service brake operates both the tractor and trailer brakes
  • the parking brake for the tractor works
  • the service brake pedal does not have excessive side play or missing, loose or incomplete anti-slip tread

7. Height marker

Check the correct vehicle height is displayed on the vehicle height marker in the cab.

Remember, the height can change, for example, when the fifth wheel is adjusted, or if the trailer is loaded, unloaded or reloaded.

8. Seatbelts

Check that seatbelts:

  • do not have any cuts, damage or fraying that may stop them from working
  • stay secure when you plug them in
  • retract against you when fitted, and fully retract when you take them off

9. Security and condition of cab, doors and steps

Check that:

  • cab mountings and tilt devices are secure
  • body panels are secure and not likely to fall off
  • all doors operate as required and secure when closed
  • steps are secure and safe to use

Check outside the vehicle

10. Lights and indicators

Check that:

  • all lights and indicators work correctly
  • all lenses are fitted, clean and the right colour
  • stop lamps come on when you apply the service brake and go out when you release it
  • marker lights are fitted and work

Check that the fuel filler cap is fitted correctly.

Turn on the engine and check underneath the vehicle for any fuel or oil leaks.

12. Security of body and wings

Check that your diesel vehicle has enough AdBlue diesel exhaust fluid and top up if necessary.

Check that the exhaust does not emit an excessive amount of smoke.

16. High voltage emergency cut-off switch

Check that:

  • you know where the high voltage emergency cut-off switch is located
  • the high voltage emergency cut off switch operates correctly
  • all high voltage electrical components are secure and not damaged

17. Alternative fuel systems and isolation

Check that:

  • you know where the fuel isolation switch is located
  • there are no leaks from the system
  • all visible components are in good condition

18. Spray suppression

  • there is no cord visible anywhere on the tyre
  • all wheel nuts are tight enough - you can check if wheel nut indicators (if fitted) have moved to do this

Check that:

  • couplings are free from debris and are in the right place
  • there are no leaks

After the initial brake test, leave the engine running so pressure can build up. This will make it easier to hear any leaks as you carry out the rest of the walkaround check.

Check that the load does not move and is not likely to move.

Make sure you use the right type of load securing system for the load.

If you’re not happy with how the load is secured or how stable it is, ask the person in charge of vehicle safety to:

  • get a competent person to assess it
  • reload or resecure it if necessary

Read detailed guidance about load securing.

Record and report the result of your check

Record and report all defects that you:

  • find during the daily walkaround check
  • become aware of during your journey

What to record


  • the vehicle registration (number plate) or identification mark
  • the date
  • details of the defects or symptoms
  • your assessment of the defects (for example, ‘dangerous’)
  • your name
  • who it was reported to

Use a form that includes a list of the items checked each day. Record ‘nil’ defects if you do not find any.

Download a template to use or use the system that your employer provides.

DVSA can ask for a record of your walkaround check at a roadside check.

If you become aware of defects during your journey

Find a safe place to stop to assess and report any defects you become aware of during your journey.

You must get dangerous defects fixed before you continue your journey.

You can get an unlimited fine and a prison sentence for using an HGV in a dangerous condition.
