An email bulletin from the DSA states that from 7 April 2014, candidates will no longer be able to take Theory Tests with foreign language 
voiceovers, or Practical Driving Tests using an interpreter. This action follows the consultation carried out earlier this year, the results of which can be read here.
Note that Special Needs candidates will still be able to take their Theory Tests with English or Welsh voiceovers, and hearing-impaired candidates will still be able to take the Theory Test in British Sign Language (BSL) and use a BSL interpreter on their Practical Test. Other candidates will still be able to take their tests in Welsh (though Lord knows why they should have to, except in order to make some sort of political statement).
I fully support this action. However, I don’t think we’ve heard the last of it just yet…
And I also predict a rush of people hurrying to take tests before the deadline, so anyone learning to drive should bear this in mind as it is possible waiting times will increase.
Can I use an interpreter on my Practical Test?
Yes, until 7 April 2014. After that time you will have to do the test in English or Welsh.
Can I do my Theory Test with a voiceover in my first language?
Yes, until 7 April 2014 – and assuming that your language is one of those supported. After that time you will have to do the test in English or Welsh.
