Prohibition Notice (PG9)

Updated: Apr 30

What is a PG9: A PG9 is a roadworthy prohibition. This is usually issued when a vehicle is in an unfit state or when a piece of valuable equipment is not working effectively. A good example of a vehicle being unfit is ‘Sharp Panel Damage’ or a faulty wheelchair ramp for a piece of equipment not working effectively.

Where can these be issued: These can be issued on the roadside which is also known as a 'spot check' as well as them also spot-checking bus depots, or wherever a PCV vehicle is stored. Usually when they spot check a number of vehicles get checked, as well as to see if the paperwork is up to date and in order.

Who can check for this?: Any authorised DVSA officer who has the correct ID card.

What do they check for: Identification – does the vehicle registration, VIN and chassis information match the legal documents. There are multiple identification plates that are placed in several different areas of the vehicle, some vehicles have more than others.

PG9 Topics:

Braking Equipment: The officer will check to make sure the brakes are working effectively from a visual and basic check point. They will check to see the service pedal is working correctly by pressing the pedal and hearing the air release as well as making sure they're no air leaks and the valves are working correctly.

Steering: The officer will check to see if the steering reacts correctly and also make sure that it does not have excessive play. These are checks to see if something is out of the ordinary.

Visibility: The officer will check for cracks and chips and check the security of the windows. They may still use a general rule of thumb called the ABC system which used to be used by MOT testers. They will also look for the correct markings in the windows and make sure every window is legal. If windows are tinted they may check to see if the tints are too extreme.

Zone A: Is 350mm wide, in the swept area of the screen and centre of the steering wheel. you should not have any chips or cracks in this zone as it may impact your vision on the road.

Zone B: Is the remainder of the swept area. This area can have minor damages such as small cracks and small chips. This is now judged by the examining authority and you may get told different ruling, these should be filled and dealt with ASAP. These will not pass an MOT if there is cracks and in some cases you may be given a prohibition .

Zone C: Is the rest of the window, you can have cracks and chips but will be judged separately and will be decided based on independent opinions. Usually they are allowed but they would ask for it to be sorted ASAP.

Lighting equipment & Electrical systems: The officer will check the vehicle to make sure all external lighting is working as well as check the electrical safety features such as the emergency stop. Inside the vehicle the officer will check to see if the step lighting and cab lighting works appropriately and that the saloon has sufficient lighting. Other electrical items include bells and the bus stopping sign for example.

Axles, wheels, tyres & suspension: The officer will check to make sure everything is safe around the axle. On the tyres they will check the tread, see if they're any cuts or bulges and also check to see if there is any punctures. On the wheel they will check the valve as well as the bolts where the wheel is secured by. They'll check the suspension to see if it sits level and if it works correctly via the kneeling etc. The airbags, valves and system must be all in working order.

Chassis & chassis attachments: The officer will check to see if there is any signs of major corrosion or anything what looks unsafe, this could be hanging wires to snapped brackets as these could all cause incidents or even fires. The chassis is the main backbone of a vehicle so it must be kept in good condition to withstand different weather conditions.

Other equipment: The officer will make sure every safety feature is in place such as a speed limiter and any legal recording devices like a tachograph is working and in calibration date. They may check seating, handrails and seatbelts if the vehicle is fitted with them, as they also come under the safety barrier.

How are the defects categorised?: There is a system in place where you will be issued an advisory where you can still drive the vehicle away, a PG9 notice or a prohibition where the vehicle cannot be moved.

Can you be prosecuted if a PG9 is severe?: The answer is yes, if DVSA believe you could have found it on your visual walk-round check you could be asked further questions or even appear in court to answer to the traffic commissioner.

If an engineer should have noticed a severe fault or have signed something off to say it has been rectified when it hasn’t the same procedure will apply depending how severe it is.

What are the prohibition notices:

Roadside Prohibition: Issued when a defect is usually severe they would usually give it to you in one of these forms below.

Immediate Prohibition: Your vehicle is too dangerous to be driven so it will be immobilised by DVSA and will have to be recovered back to the depot of the operator or to where the vehicle is stored. You can be prosecuted if DVSA choose to.

Delayed Prohibition: You will get a prohibition with a delayed effect, what this means is the vehicle can return to depot or to where the vehicle is stored without a recovery lorry. When the vehicle is back at their home location you have 10 days to fix the issues and for it to be reinspected by DVSA, the prohibition will be removed if they're happy with the repair.
