Motor Cab, Maxi Cab, Omnibus and Bus: The Definitions Untangled

The Act sorts passenger vehicles by seats, counted excluding the driver: a motor cab carries up to six passengers for hire, a maxi cab more than six and up to twelve, an omnibus is any vehicle built for more than six persons, and the stage carriage is the omnibus run on separate fares. The definitions look pedantic until a permit, a tax slab or an aggregator licence turns on one seat.

1. The answer in brief

• Motor cab (section 2(25)): a motor vehicle constructed or adapted to carry not more than six passengers excluding the driver, for hire or reward: the taxi, the app cab, the airport sedan.
• Maxi cab (section 2(22)): more than six but not more than twelve passengers, for hire or reward: the Innova crowd carrier, the twelve seat van.
• Omnibus (section 2(29)): any vehicle constructed or adapted to carry more than six persons excluding the driver, the genus covering buses of every kind.
• Stage and contract carriage then classify the use: separate fares stage by stage against engagement as a whole, the permit families built on them.

2. Why the one seat matters

• Permit class: cab permits, their conditions and the taximeter requirement attach by these definitions; a thirteenth seat moves the vehicle into bus territory with different permits and fitness expectations.
• Taxation: State motor vehicle taxes slab by seating, and the cab to maxi cab line is a tax line in most schedules.
• Aggregator fleets are licensed around motor cabs and maxi cabs, the guidelines assuming these classes; the airport shuttle's seating decides which rules it answers.
• Construction or adaptation is the test, not the day's load: an eight seater carrying three passengers remains a maxi cab class vehicle, and unauthorised seat additions are section 52 alterations.

3. Quick Revision

1. Count passengers excluding the driver, always.
2. Classify the vehicle before classifying the use.
3. Match the permit to the class the seats give.
4. Watch the tax slab at the six and twelve seat lines.
5. Treat seat changes as recordable alterations.

4. Frequently Asked Questions

Is a seven seater family SUV a maxi cab?

Only when it plies for hire. The maxi cab definition carries two limbs, the seating band and the words for hire or reward, so the private seven seater carrying its own family is simply a light motor vehicle on a private registration, outside the cab definitions entirely; the same vehicle registered as a transport vehicle and run commercially becomes a maxi cab with the permit, tax and driver consequences of that class. The distinction explains the plate colours at the airport: identical vehicles, white plates for the family, yellow for the fleet, the seating identical and the use entirely different. For exams, quote both limbs; for buyers, know that converting the family SUV to commercial use is a re-registration into the transport class, not a side hustle on the private papers.

Why does the omnibus definition say persons while the cab definitions say passengers?

Because the omnibus is the construction genus while the cabs are hire classes, and the drafting tracks the difference. The omnibus definition describes what the vehicle is built to carry, more than six persons excluding the driver, with no hire or reward requirement at all, serving as the platform definition on which buses, private service vehicles and educational institution buses are built; the cab definitions describe commercial carrying capacity, passengers carried for hire or reward, because fares and permits are counted in paying seats. The practical consequence is that the same twelve seat van can be an omnibus by build, a maxi cab when run for hire, and a private service vehicle when an employer runs it for staff, three labels, one machine, each pulling its own chapter of the Act, which is precisely the kind of definitional layering examiners love to test.
