We publish for you sample ADR tests which participants may encounter. ADR test is a one-choice test, so you only need to mark one answer out of the three suggested.

The following ADR examinations shall be carried out:

  • basic course - 60 minutes in duration and the participant must answer 30 questions of which 20 must be answered correctly
  • specialised course in the carriage of dangerous goods by road in tankers - this course takes 40 minutes and the participant must answer 18 questions of which 12 must be answered correctly
  • Specialised course in the carriage of dangerous goods by road of Class 1 - explosives and explosive articles - lasting 30 minutes and the participant must answer 15 questions of which 10 correct answers are required to pass
  • specialist course in the carriage of dangerous goods by road of Class 7 - radioactive material - 30 minutes' duration and the participant must answer 15 questions of which 10 correct answers are required to pass

We have prepared ADR tests for you for the basic course and all three types of specialist courses. These are sample questions, but they will give you an idea of the specifics of the test. We recommend that you practice the ADR tests before you take the exam. During our courses, you will learn everything you need to know about carrying ADR goods. You are welcome!
