Final answer:
The Ministry of Transportation defines a bus as a motor vehicle used for transporting people and carrying 10 or more passengers. In the case of mergers, such as between Greyhound Lines and Trailways Transportation System, defining the market broadly can be beneficial to avoid monopoly concerns and facilitate regulatory approval.
Step-by-step explanation:
A bus is defined by the Ministry of Transportation as a motor vehicle used for the transportation of people and carrying 10 or more passengers. This definition helps to categorize and regulate vehicles according to their carrying capacity, ensuring appropriate safety and legal standards are met. In the context of transportation services like buses, understanding this definition is crucial when discussing the operation, logistics, or the legal aspects of public transport and private charter services.
Addressing the concept of a defined market, in the case of the merger between Greyhound Lines, Inc. and Trailways Transportation System, the bus companies preferred the broader definition of 'the market for intercity transportation', which includes personal cars, car rentals, passenger trains, and commuter air flights. Choosing this definition gave a more comprehensive view of the competition they faced, and demonstrated that they only held a small fraction of the entire intercity transport market. This strategic choice aimed to avoid the impression of creating a monopoly in the bus service sector alone and thus facilitated the approval of their merger.
