On the morning of 24 September 2026, many ANM buses did not leave their depots in Naples, leaving hundreds of passengers without transport.

According to Il Mattino, the disruption centered in part on the ANM depot in via Cavalleggeri. Only newer buses reportedly departed from there, while older vehicles remained in the depot because drivers considered them non-compliant with safety requirements.

Drivers began reporting faults and anomalies on buses, according to the report. USB representative Marco Sansone was quoted describing the drivers' safety concerns and calling for an urgent meeting with the relevant authorities.

The stoppage coincided with the start of preliminary events for the America's Cup, when approximately 600,000 people were expected in Naples. The timing increased pressure on public transport at a moment of exceptionally high demand.

Sansone also criticized the lack of increased staffing and incentives for bus and parking services during the event period.

It remains unclear how long the disruption lasted, how many buses were affected, or how many routes were suspended. Normal service resumption details were not provided in the available reporting.
