Driver Vehicle Standards Agency
Youre responsible for making sure your vehicle is safe to drive.
Carry out a walkaround check of the vehicle before your journey to make sure its 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 youre 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.
