Prepare for Your MOT – A Guide by Woodstock Motors

Prepare for MOT

What is the MOT test?

The Ministry of Transport (MOT) test is an annual vehicle safety and road worthiness test which examines road vehicles on a number of criteria to determine whether or not they are safe to be used on public roads.

When is my MOT due?

Your vehicle is first required to undergo an MOT test three years after initial registration (i.e. any vehicles initially registered in 2013 required their first MOT in 2016).

Thereafter, vehicles must undergo an MOT test every year, with the due date determined by its last test (i.e. any vehicles which passed an MOT test in October 2016 are due for another MOT in October 2017).

In some cases, vehicles require their first MOT within one year of initial registration. A list of such vehicles can be found on the UK Government’s website.

MOT classifications

For the purposes of MOT testing, vehicles are categorised into certain classifications based upon criteria such as the size and weight of the vehicle, and how many passengers it can carry. Vehicle classifications for MOT tests are as follows:
Class 1

  • Motorbikes (engine size up to 200 cm3)
  • Motorbikes (engine size up to 200 cm3)

How to properly prepare for your MOT

  • Ensure that all vehicle controls (e.g. indicators, windscreen wipers, lights) are working properly.
  • Ensure that your vehicle’s fuel, oil, brake fluid and windscreen wash is topped up.
  • Ensure that seat belts and doors can be opened and closed.
  • Check that all items such as seats, steering wheel and registration plates are fastened securely.
  • Check that your tyres’ tread is at least 1.6mm and that all tyres on the vehicle are consistent in terms of size.
  • Ensure that there are no sharp edges or potentially hazardous damage to the vehicle’s exterior.
  • Bounce each corner of the vehicle to see if it goes down under pressure, rises to full height and then settles.
  • Ensure that you can see 100% clearly out through the windscreen. Also, check that your headlamps’ brightness isn’t curtailed by an accumulation of debris.
  • Check that your exhaust isn’t emitting smoke or leaking.
  • Bring the vehicle registration document, letter of appointment and any current Certificate/Notice of Refusal with you to the MOT test.

What happens during an MOT test?

  1. Show up in good time (at least 10 minutes early) on the day of the test, as per the appointment notice you will have received either in the post, by text or on email. If you cannot make it to the test centre for the appointment, you can ask someone else to present your vehicle for the test.
  2. When you arrive at the test centre, park in the lane specified in your appointment notice. Keep your engine running at normal temperature for the emissions test.
  3. You will be asked to drive your vehicle into the testing hall when the testers are ready.
  4. After the first few checks, the tester will take control of your vehicle and you should go to the test centre’s waiting area. You will be able to see the test being carried out. Passengers and pets are not permitted in the testing hall at any stage.
  5. In rare cases, your vehicle may be chosen for a randomly administered quality control re-check. However, the probability of this happening is low.
  6. A few minutes after the test is finished, you will be informed of your vehicle’s result. You will either get a vehicle test certificate (if passed) or a list of faults which need to be repaired (if failed).

What to do after MOT
After your MOT, you will be given documentation based on the outcome of the test.

What to do after an MOT

If the vehicle passes
If your vehicle is deemed to have passed its MOT test, you will be given an MOT certificate confirming that your vehicle is officially in a roadworthy condition. The certificate comes in two parts: one of which contains test details (for submission when taxing your vehicle), the other containing an inspection report. You should continue to drive safely and maintain your vehicle’s condition for the duration of the MOT certification.

If the vehicle fails
If your vehicle is deemed to have failed its MOT test, you will be given a document detailing the faults which need to be addressed. You will be able to book a retest for a reduced fee within 21 days of the initial test. If you leave it any later to book, the retest will cost the full price of an initial test.

What scenarios are exempt from MOT testing?

In the vast majority of cases, a vehicle which is less than three years old does not require an MOT, although some vehicles could require an MOT within one year of initial registration.

The following vehicles are fully exempt from MOT testing, provided that you have completed a Declaration of Exemption form and submitted it to the Driver & Vehicle Licensing Agency:

  • Tractors
  • Track-laying vehicles
  • Articulated vehicles other than lorries & buses
  • Works trucks
  • Vehicles which are driven exclusively on land owned by the vehicle owner whereby no more than 6 miles is driven in a week
  • Hackneys/taxis which have been taxed by Transport for London or an authorised local authority
  • Vehicles for police purposes
  • Electricity-powered goods vehicles
  • Trams
  • Non-auxiliary trolley vehicles
  • Vehicles authorised for use by a Special Types General Order
  • Vehicles driven on UK islands without a suitable connecting bridge/tunnel/etc to mainland UK
  • Vehicles manufactured or registered prior to 1st January 1960

Getting an MOT retest

You can book an MOT retest for a fee smaller than that of the initial test fee, provided you book it within 21 days of the initial test. Otherwise, you will be charged the full test amount again.

However, if you bring your vehicle back to the same testing station before the end of the next working day for a partial retest, or if you leave the vehicle at the testing station for repair within 10 working days, no additional fee will be charged.

If the vehicle is removed from the testing station for repair and brought back for a partial retest within 10 working days, you will only need to pay a partial retest fee.

You should note that only one partial retest can be obtained for each full test.

How to appeal an MOT result

If your vehicle fails the MOT test and you believe that the result was incorrect or unfair, you can lodge an appeal to get the result overturned. The steps involved in this process are as follows:

  1. Obtain a VS17 form from the testing station where the test was carried out, or download it from the UK Government website .
  2. Complete the form and send it to your local Driver & Vehicle Standards Agency (DVSA) office within 14 days. You must also send your full test fee when lodging the appeal.
  3. The DVSA will offer you an appointment within 5 working days to get the vehicle rechecked. If it is successful and the result is overturned, the fee (or part thereof) will be returned to you.
