If you are no longer medically fit for category C, this does not automatically remove every driving entitlement. Category C belongs to medical group 2. Category B is assessed under the requirements of group 1.

The decisive question is therefore which categories the medical assessment and the authority decision actually cover. A restriction to group 1 may be possible if the requirements for category B are still met. The decision must make that scope clear.

Category C and category B are assessed separately

Section 1 of the Austrian Health Requirements Regulation for Driving Licences distinguishes group 1 and group 2. Group 1 includes, among others, categories AM, A1, A2, A, B, BE and F. Categories C, C1, CE, C1E, D, D1, DE and D1E belong to group 2.

This distinction matters when assessing whether a medical restriction automatically affects every category. The stricter group 2 requirements may mean that category C can no longer be issued or renewed while the requirements for group 1 remain satisfied. This is not an automatic consequence. The concrete medical assessment and the operative part of the authority decision remain decisive.

Category scope

Which category is affected by the medical issue?

The groups have different requirements and must not be treated as identical.

Group 2 and group 1 compared
Area Group 2 Group 1
Typical category C, C1, CE and other heavy vehicle categories B and other group 1 categories
Medical standard Additional requirements for medical fitness The separate group 1 requirements
Possible consequence C may be restricted or no longer issued B may remain if its requirements are met
Evidence Assessment and decision for the affected categories Separate assessment of the remaining entitlement

Whether category B remains is not decided by the job title, but by the concrete medical assessment.

Group 2 applies a stricter medical standard

Section 3 of the Austrian Health Requirements Regulation describes the medical examination. Depending on the case, it covers the medical history, general impression, eyesight, hearing, the cardiovascular system, mobility and neurological signs. Group 2 has stricter requirements in several areas because heavy vehicles and professional use can involve additional risks.

One individual finding does not always decide every category. The assessment must bring the medical situation and the intended category scope together. Where specific findings require it, section 8 FSG can require an official medical assessment or further specialist reports. Prepare not only the report that led to the question about category C, but the complete medical assessment.

The medical assessment focus area explains the medical and administrative process. You can also use the medical assessment document checklist to organise the records.

When category B may remain despite a restriction

Category B may remain if the medical assessment confirms fitness under the group 1 requirements. It is not enough to state that the person may no longer drive category C professionally. The assessment and decision should show what remaining fitness is accepted and whether conditions, aids or periodic examinations apply.

For example, a condition may no longer satisfy the stricter requirements for category C while still allowing a passenger car under category B with a specific condition. In that situation, the authority may limit the entitlement to group 1. Whether this is possible depends on the medical findings, the assessment and the exact wording of the decision.

Our guidance on medical fitness for professional drivers addresses separate evidence for C and D categories. This article focuses on the remaining entitlement after an unfavourable assessment for category C.

Decision review

Four steps clarify the remaining category scope

Read the medical finding, assessment and operative part in the same order.

  1. 01
    Step 1

    Record the finding and reason

    Which medical fact triggered the review of category C?

    Organise reports, previous findings and the authority request. One doctor’s letter does not by itself show which categories are legally affected.

    Review points: section 8 FSG, section 3 FSG-GV

  2. 02
    Step 2

    Read the assessment by group

    Check whether the assessment distinguishes group 1 and group 2.

    Look for the concrete statement on B, C and any conditions. The phrase “unfit” must not be read without the category scope.

    Review points: section 1 FSG-GV, section 8(3) FSG

  3. 03
    Step 3

    Relate the operative part to categories

    The decision should show whether only C or the whole entitlement is affected.

    Section 24(1) FSG distinguishes withdrawal from conditions, time limits and factual restrictions. Mark every category named in the operative part.

    Review points: section 24(1) FSG

  4. 04
    Step 4

    Secure conditions and evidence

    Record aids, reviews, deadlines and later assessments separately.

    A remaining category B may carry conditions. Record every review and item of evidence, not only the expiry date.

    Review points: section 8(3) FSG, section 24 FSG

The operative part must state the restricted scope

Section 24(1) FSG distinguishes withdrawal from restrictions through conditions, time limits, geographic or factual limitations. A medical decision should therefore make clear whether it affects C, several group 2 categories or the whole driving entitlement.

Do not review the decision by its heading alone. Read the operative part, reasons, attachments and information on legal remedies together. A covering letter cannot replace the binding operative part. The withdrawal decision check helps record categories, period, service and ordered measures in an organised way.

If the scope is unclear or the assessment and operative part do not match, preserve both documents in full. The most important records are usually the decision with proof of service, the medical assessment and a copy of the driving licence.

Do not confuse assessment, condition and time limit

Section 8(3) FSG distinguishes different forms of medical fitness. An assessment may find fitness, conditional or restricted fitness, or unfitness. It may lead to time limits, conditions, periodic examinations or aids. These elements do not have the same meaning as the question which category the authority withdraws or restricts in the operative part.

Glasses, vehicle adaptations or periodic checks may support fitness for one category. They do not automatically mean that every higher category remains valid. Conversely, losing fitness for C does not necessarily remove a suitable group 1 entitlement.

The driver disclosure focus area concerns a different administrative procedure and cannot replace a medical assessment. Sort each document by subject: request for an assessment, medical report, decision on category scope and later proof of compliance.

Overview of all answers.

Keep these documents together

  • complete decision with operative part, reasons and information on legal remedies
  • medical or official assessment with every attachment
  • copy of the driving licence showing categories and codes
  • specialist reports and earlier periodic assessments
  • evidence of aids, conditions and completed checks
  • proof of service, authority requests and your own submissions
  • evidence of professional work if category C is needed for employment

Together, these documents show whether only group 2 categories or also the group 1 entitlement is affected. The document check does not replace legal review, but it supports a complete preparation.

FAQ

Frequently asked questions about categories C and B

Do I automatically lose category B if I am no longer fit for C? +
No. C belongs to group 2 and B to group 1. Fitness for B must be assessed separately from the medical assessment and the actual decision.
Can the authority restrict only category C? +
This may be possible if the medical requirements for group 1 remain satisfied. The decision must show which categories and conditions it actually covers.
Which documents are important for the review? +
The complete assessment, decision with proof of service, licence copy, medical reports and evidence concerning conditions or periodic examinations are particularly important.
