Since the written theory paper was added to the practical driving test last July, more than 1 million prospective drivers have sat the test, with pass rates currently running at about 60 per cent.
Research carried out by the Driving Standards Agency shows that an average "first-time pass" candidate spends between five and 10 hours studying the questions before taking the test.
The new questions - which bring to 700 the total available to examiners - offer candidates a wide range of driving decisions and dilemmas, with a multiple choice of possible responses.
DSA chief executive Bernard Herdan said: "The new questions put additional emphasis on certain aspects of driving theory which we feel need more attention from new drivers, such as being alert to vulnerable road users, so that theory testing can make as great a contribution as possible to overall road safety."Reuse content
