When can the authorities order a bus driver to undergo a fitness assessment?

The selected combination is correct because it reflects the scenarios in which authorities may require a bus driver to undergo a fitness assessment.

1. Serious violations of road traffic regulations can indicate a lack of adherence to necessary safety practices.
2. Committing a serious road traffic offense suggests that the driver has engaged in behavior that puts the safety of others at risk, warranting further evaluation.
3. Indications of high aggression potential are essential for assessing a driver’s capability to operate a vehicle safely, particularly when it comes to passenger transport.

By requiring an assessment in these circumstances, German traffic laws aim to ensure the safety of all road users and maintain high standards for public transport services. Ensuring that all these scenarios are included in the assessment criteria helps create a comprehensive approach to evaluating a driver’s fitness for duty.
