Improved safety, that's the theory.
The Driving Standards Agency says the increase in the number of multiple choice questions will help broaden candidates' knowledge and lead to higher standards.
DSA spokesperson Jill Lewis, says: "It is important that candidates prepare thoroughly for their theory tests in the same way that they would any other exam. Increasing the number of questions means the test ensures comprehensive coverage of the whole syllabus."
Currently both car and motorcycle bike tests involve 35 questions and candidates must get 30 right.
But from September, the number of questions will rise to 50 with a pass score of 43.
The time allowed for the multiple-choice part will increase to 57 minutes, and fees will increase from pounds 21.50 to pounds 28.50.
A NEW book called Great Small Fiats is published by Veloce at pounds 17 and traces them from the birth of the Topolino in the 1930s up to the current Panda and Nuova 500.
Each of the selected models is described in detail from conception through to current ownership in the hands of collectors and enthusiasts. The chapters include practical information on buying and running a small Fiat and restoration advice for the older cars.
