Question:   I have been having some problems working out when to use PRS duringthe MOT. I realise that it can only be used after test, but there appearsto be some difference of opinion on whether it is used before or after repairs tothe vehicle are completed. Can you shed some light on this

Expert Answer:   
After having been to various VOSA MOT seminars over the last few months, I’ve been asked several times to explain PRS and retests. It seems that the requirements for PRS (or Pass after Rectification at Station) are often misunderstood, so I’m happy to help.

PRS was designed to save time by allowing repairs to be completed before entering the result of the test. This allows a tester to fail and pass the vehicle in a single action at one visit to the VTS Device.

PRS is a partial re-examination for which no fee can be charged and during which the tester cannot register any new tests. If you need to test a second vehicle before repairs to the first are complete, you cannot use PRS. Instead, you must fail the first vehicle and follow the partial retest procedure when you come back to it later in the day.

So, PRS can only be used if a vehicle has failed the test for items that you expect can be repaired within the next hour or so. Typically, this will cover items such as lights or tyres, but there is no definitive list.

Once you have started repairs, you will soon know how long these are likely to take and whether you can get hold of the parts you need. If it becomes clear that repairs are unlikely to be completed within the hour, you should fail the vehicle. If you choose not to use PRS or the situation doesn’t allow its use, you should simply fail the vehicle, then complete a retest as appropriate.

Talking of retests, you can carry out a fast track retest if:

• you do not need to print a checklist, and
• the retest doesn’t involve measured items, and
• you do not need to preserve the expiry date, and
• you do not need to access Vehicle Specific Information, and
• the vehicle is retested by the same VTS no later than 10 working days after the date of the original test.

Otherwise you must carry out a partial retest in the same way as you would do if the vehicle failed the test for measurable items. In any other circumstance a full retest must be conducted. This includes vehicles that fail their retest, as only one partial re-examination is permitted per full examination.

Remember you can only enter a pass on the system or issue a VT20 once the vehicle has been repaired, retested and meets the requirements!
