An example from the question set

What characterises compatibility group A for explosives?

Primary explosive substances, very sensitive to impact and friction
Secondary explosive substances such as TNT and dynamite, without their own means of initiation
Articles containing a primary explosive substance
Articles whose hazard is confined within the package
Explanation

Compatibility group A is primary explosive substances, that is, substances that can detonate from a small stimulus such as impact, friction, heat or a spark. Examples are lead azide and mercury fulminate. Such substances are used in small quantities to set off the main explosive. Because they are so sensitive, group A may not be loaded together with other compatibility groups. Secondary explosives such as TNT belong to group D, articles containing a primary explosive substance to group B, and group S is articles whose hazard is confined within the package.

Passed with flying colours on the first attempt! Class A
Bought both «Veien til førerkortet» for Class A and Car. Read through them fairly averagely. But it's mainly Prøve.no that helped me out! A thousand thanks for a brilliant app.

Frequently asked questions

How many errors can you have on the ADR class 1 exam?

You can have a maximum of 3 errors out of 15 questions on the ADR class 1 exam (1-ADR). You need at least 12 of 15 correct to pass at Statens vegvesen.

How long does the ADR class 1 exam take?

You have 75 minutes for the ADR class 1 exam at Statens vegvesen. If you take the combined exam (G-1ADR), the 135 minutes for the basic course are added, giving 210 minutes in total on the same day.

Can I take the ADR class 1 exam without the basic course?

No. The ADR basic course (G-ADR) is the mandatory foundation for the class 1 specialization. Most candidates take the basic course and class 1 on the same exam day as a combined exam (G-1ADR). Taking only the class 1 exam is relevant only if you already hold a valid ADR basic certificate.

How long is the ADR class 1 specialization valid?

The ADR competence certificate with class 1 specialization is valid for 5 years from the date of issue. Before it expires you must pass renewal exams for both the basic course and the class 1 module to retain the qualification.

Which ADR specialisations are there?

ADR training consists of a basic course (grunnkurs) and three specialisation courses: tank, class 1 (explosives) and class 7 (radioactive material). This test covers the class 1 (explosives) specialisation, which builds on the basic course.
