In this article, you'll learn what the tractor theory exam involves, which topics are covered, what the costs are, and how to prepare effectively.
What Is a Category T Driving Licence?
The Category T driving licence is intended for drivers of agricultural and forestry tractors, limited-speed vehicles (MMBS), and certain mobile machines that operate on public roads.
Since 1 July 2015, a T licence has been mandatory for drivers of these vehicles, unless they qualify under a transitional arrangement.
With a T licence, you may drive:
- Agricultural tractors
- Forestry tractors
- Harvesting machines
- Mobile agricultural vehicles
- Limited-speed motor vehicles
When Do You Need a T Licence?
You need a T licence when driving an agricultural or forestry vehicle on public roads.
For example, if you work in agriculture, contracting services, or green space maintenance, a T licence is often required to carry out your work.

What Is the CBR Tractor Theory Exam?
The Category T theory exam assesses whether you have sufficient knowledge of traffic rules, traffic awareness, and the specific traffic risks associated with operating agricultural vehicles.
The exam consists of multiple-choice questions and traffic scenarios that you may encounter while driving a tractor or similar vehicle.
The goal is to ensure that you can participate safely in traffic.
Which Topics Are Covered?
During the theory exam, you will be tested on several subjects.
Traffic Rules
You must know the general traffic regulations that apply to all road users.
Vehicle Knowledge
You will learn how agricultural vehicles operate and which technical aspects are important for road safety.
Traffic Awareness
You must be able to assess traffic situations and make safe decisions.
Safety and Risks
Agricultural vehicles are large, heavy, and often less manoeuvrable than passenger cars. For this reason, special attention is given to risk recognition and safe driving behaviour.
Loads and Vehicle Dimensions
You will also receive questions about vehicle dimensions, weight limits, and the safe transportation of loads.

At What Age Can You Take the Theory Exam?
You may take the Category T theory exam from the age of 15.5 years.
You may take the practical exam from the age of 16. Once you have passed both the theory and practical exams, you can apply for your T driving licence.
How Can You Prepare for the Theory Exam?
Good preparation significantly increases your chances of passing.
Study the Theory
Use up-to-date theory books or online learning materials specifically designed for Category T.
Take Practice Exams
Practice exams help you become familiar with the exam format and identify which topics require extra attention.
Learn the Rules for Agricultural Vehicles
In addition to general traffic rules, you must also understand the regulations that specifically apply to tractors and agricultural machinery.
Follow a Theory Course
A theory course can help you understand the material more quickly and study more efficiently.
How Much Does the Tractor Theory Exam Cost?
You must pay an examination fee to the CBR for the theory exam. Current fees may change annually.
In addition to the exam fee, you may need to budget for:
- Theory books
- Online practice exams
- Theory courses
- Practical driving lessons
What Happens If You Fail?
If you do not pass, you may retake the theory exam.

After the Theory Exam
Once you pass the theory exam, you can continue preparing for the Category T practical exam.
