Here are the theory test questions for A66 Compact Crane.
During the theory test you'll be asked a maximum of 40 questions.
Please note that your paper will include all the questions we have marked here with an asterisk *. In addition you will have a random selection of the other questions that are not marked here with an asterisk.
These questions will appear on every A66 paper
