A tougher theory section of the UK driving test has come into effect, with learners now required to answer more questions to gain a pass.
Drivers need to pass both a theory and practical test
Candidates need to correctly answer 43 out of 50 multiple-choice questions on the Highway Code, compared with the old standard of 30 out of 35 questions.
The Driving Standards Agency said the expanded exam means learners will now be tested on a wider range of topics.
The change coincides with a rise in the cost of the test from £21.50 to £28.50.
The DSA has not enlarged the test syllabus but has introduced additional questions on existing areas.
The questions will be taken from a pool of more than 1,000 - up from 900.
The theory test's percentage pass mark remains about the same at 86%.
Learner drivers need to pass the theory section before being allowed to go on to complete a practical test to gain their full licence.
The Driving Standards Agency said the increase in questions would help broaden knowledge and lead to higher standards.
"It is important that candidates prepare thoroughly for their theory tests in the same way they would any other exam," said Jill Lewis, DSA's head of lifelong learning.
"Increasing the number of questions means that the test ensures comprehensive coverage of the whole syllabus."
