Gain access to the profession for the mechanical, electrical or electronic repair and maintenance of large vehicles (over 3.5 tonnes)
Are you planning to open a garage to repair lorries or commercial vehicles? Or would you like to add this service to your existing business? In this case, you need to prove that you have the professional skills required to work on large vehicles (over 3.5 tonnes). If you don't have a diploma or experience in this field, you can obtain a certificate by sitting the central jury exam.

Which activities require professional skills for large vehicles?
This includes the repair and maintenance of mechanical, electrical and electronic components of large vehicles. Large vehicles include vans, lorries, tractors and other motor vehicles with a mass of over 3.5 tonnes.
In addition to skills specific to motor vehicles up to 3.5 tonnes, you also need to prove that you have the cross-sectoral skills of the vehicle sector. In addition, if your project involves a new business, you'll need basic management knowledge.Which activities are exempt?
Proof is not required for the following activities:
- Activities relating to "ancestors". These are motor vehicles that have been on the road for at least 25 years and are exempt from certain technical inspection requirements;
- You receive your results directly after the test.
- Work required during recovery or towing by emergency road services or at the customer's home;
- The following maintenance activities:
- Fitting tyres, changing wheels and replacing rims;
- Replacing windows or windscreen wipers;
- Cleaning;
- Installing or replacing fire extinguishers.
If in doubt, contact a Business Counter. They will be able to tell you whether or not you qualify for an exemption.
How can I prove my skills?
Skills can be proven in two ways:
- With a diploma or certificate;
- With 3 years' full-time or 5 years' part-time professional experience within the last 15 years.
If you don't have either, you can obtain a certificate by sitting the professional skills exam for motor vehicles over 3.5 tonnes (20103) before the Central Jury.
