Which authority must be notified for certain accidents involving ground vehicles?

The National Transportation Safety Board (NTSB) is the appropriate authority that must be notified for certain accidents involving ground vehicles. The NTSB is responsible for investigating and determining the probable cause of transportation accidents, including those related to ground vehicles such as planes, trains, and automobiles.

In the context of accidents occurring on the airport ramp involving ground vehicles, the NTSB plays a crucial role in ensuring safety by conducting thorough investigations and providing recommendations to improve safety standards and practices. Incidents that could lead to serious injuries or fatalities, or that involve significant damage, typically trigger the need for NTSB involvement.

By notifying the NTSB in these situations, you ensure that proper protocols are followed and that lessons can be learned to prevent future occurrences. This reinforces a culture of safety and accountability within the transportation industry.
