As part of your driving test you will be asked 2 vehicle safety questions at the start of the test (also known as show me/tell me).

The examiner will ask you

ONE show me question where you have to show how you would carry out a check (i will go over the questions with reference to my car so you will not have to worry where buttons and switches are and how to look under the bonnet).
ONE tell me question where you have to explain how you would carry out the check.

The present questions are available at www.gov.uk/government/car-show-me-tell-me-vehicle-safety-questions

These will change from 4th December 2017 when the new driving test structure comes into force.
