It uses minibuses to provide quicker transport and to serve areas that standard Hong Kong bus lines cannot reach as efficiently.

Minibuses typically offer a faster and more efficient transportation solution due to their small size, limited carrying capacity, frequency and diverse range of routes, although their fares are generally slightly higher than those of standard buses.

RMBs substitute red for green on the external roof of the car, although originally the distinction was made by the colour of the stripe around the midsection of the vehicle.

On all public minibuses, a large digital speedometer must also be installed on the interior ceiling, adjacent to the driver's seat, facing passengers, enabling them to monitor the current speed.

The buses had a black and white chequered stripe and were colloquially referred to as zebra cars (Chinese: 斑馬車; Cantonese Yale: Bāanmáh chē).

[7] The destination signage at the top front of minibuses did not appear until 1977 and the rear bench seat disappeared altogether with the prevalence of air-conditioning equipment installation.

A minibus can generally be hailed down at any point along a route, subject to traffic regulations, although sometimes particular stops are marked out.

Tourists have difficulty with this system, as it generally requires both intimate local street knowledge and prior training in Cantonese.

Passengers often call out landmarks, intersecting streets and other distinctive features (such as immediately before or after a no-stopping zone).

Some Green minibuses are now equipped with a bell operated similarly to those found on the larger buses, and ringing it indicates that a passenger wishes to alight at the next stop.

Red minibuses (RMBs)[1] are a kind of share taxi, which run a non-scheduled service, although routes may, in effect, become fixed over time.

Destinations displayed on RMBs are sometimes identified by landmarks long gone, such as Daimaru (Chinese: 大丸) in Causeway Bay, the defunct department store.

There are a few of the new buses in service at the moment, but because it is only legal to have 16 passengers in a minibus, the extra area is used as a luggage rack.
