Information for candidates

PDP Candidate


All petroleum tanker drivers should have gained a Petroleum Driver Passport (PDP) during 2014.

In that year, they had the option of either a full PDP or an interim PDP.

A driver would have taken the full PDP if their ADR was due to be renewed in 2014, or if they required their first ADR. If their ADR was not due for renewal during 2014, they would have taken an interim PDP. Either route would have made the PDP card valid up to the expiry date of their ADR card.

From 2015...

To achieve the PDP after 2015, drivers should undertake PDP training and a full written (multiple choice) assessment, set by SQA. Drivers will also take a practical assessment with a qualified and approved PDP assessor.

Annual Training

When drivers have gained a card (eg valid up to 15th September 2023), they will have to take annual classroom training and an annual practical assessment for their PDP to remain valid.

The annual practical assessment should be sat in the four months leading up to the expiry date and month (in this example, that would be between 15th May to 15th September) each year. 
​The annual classroom training should be sat anytime in the calendar year (up until 31/12 of each year).

Should a driver miss any one of these windows, the card will become invalid and you will have to sit either a 22P or a 22T to revalidate the card, depending on what window you have missed.
These modules now work independently of one another so, for example, if you miss your practical window, you must sit a 22P to revalidate. However, if you are still in your 21T window (ie before 31/12), you can still sit a 21T.

A record of a drivers annual training and assessment will be held on SQA’s secure system.


The PDP contains classroom training with a written exam along with a practical assessment, both of which need to be completed every five years. Drivers are also required to attend classroom training and a practical assessment every 12 months to maintain the validity of their PDP.

There must be no more than four months between passing the two elements that make up the PDP (classroom training with exam (25W) and a practical assessment (25P). These can be sat in any order.
