CAP KA and KB: differences and vehicles covered

The CAP KA applies to vehicles requiring an A1, A2 or A licence; the KB is linked to B1 or B category vehicles and the professional services listed by the MIT. Check current requirements and procedures before applying.

Which service is the CAP linked to?

KA and KB are professional qualification certificates linked to driving licences for certain passenger transport activities. The MIT links KA to vehicles requiring an A1, A2 or A licence, and KB to vehicles requiring B1 or B. The CAP is relevant to services such as chauffeur hire and taxi services, under the rules that apply to the area and activity.

The distinction is not only about the type of vehicle: you also need to check whether the service you will provide requires the certificate and which local permits or additional requirements apply. A CAP does not replace the correct category of driving licence, nor does it automatically grant a taxi licence or chauffeur-hire authorisation. Rules on permits, registration and professional requirements may involve the Comune, Region and Motorizzazione.

For the CAP examination route, the MIT lists possession of the corresponding driving licence, a certificate of satisfactory attendance at a first-aid course, and an age requirement of 21 in the procedure described. Procedures and terminology may be updated, so consult the official page and the office responsible for the service in the Comune where you intend to work before collecting documents or paying fees.

• KA: for vehicles requiring an A1, A2 or A licence.
• KB: for vehicles requiring a B1 or B licence.
• The CAP is separate from the driving licence and taxi/chauffeur-hire authorisations.
• Check the current age, first-aid and administrative requirements.

How to prepare before applying

Describe the planned service precisely: taxi, chauffeur hire or another activity; specify the vehicle and the licence you hold. Ask the office whether CAP KA or KB is required and which local permits apply. The rules may distinguish between driving the vehicle, holding a professional qualification and having the right to offer the service, so asking only “which licence do I need?” may not be enough.

The CAP application is handled by the Motorizzazione under the ministerial procedure; check current forms and payments on the Portale dell’Automobilista. If your plans include a municipal service, also check local regulations and the requirements for the permit.
