In addition to the island-wide services, Douglas Corporation also operated a fleet of buses around the capital, distinctive by their yellow livery.

Today, this site has been given over to a car park, whilst buses use roadside lay-bys on Lord Street itself.

When the service was bought by the Isle of Man government in 1976 the buses carried National Transport logos and a new livery, predominantly of red with white trim, having previously carried a variation of this colour scheme under the Road Services banner.

During this period the buses carried a variety of advertisements along their side panels, with several distinctive buses carrying all-over advertising for local businesses including the Gaiety Theatre, Lombard Bank, Curraghs Wildlife Park and the National Coal Board.

By 1987 the white banding had become cream in colour, and the full Isle of Man Transport name was added to all vehicles.

In April 2009, eleven new Wright Eclipse Gemini 2 bodied Volvo B9TLs were added to the fleet, carrying a maroon and cream livery with the Bus Vannin branding which is now used in all literature and timetabling information.

Text also appears in Manx Gaelic on these, and digital destination displays on the vehicles also have an option to show the place names in the language as well.

There are three bus depots on the island which provide passenger facilities and storage areas for off-duty buses.

At Port Erin and at Ramsey, these are combined at one location[dubious – discuss], while in Douglas the Banks Circus site has a workshop and bus yard, with no passenger facilities.

The yard at Port Erin is on the site of former railway platforms whilst the original garage now houses the Port Erin Railway Museum which opened in 1975; the current garage was built as a replacement the following year and remains open today.

The three routes (N1, N3, N5) depart Lord Street in the capital of Douglas on Fri and Sat nights at 00:15 and 01:15 serving the towns of Port St Mary, Ramsey and Peel.

Over the Christmas 2020 period the Hullad Oie Night Owl services operated Friday and Saturday evenings from 4 to 19 December departing from Douglas at the usual times.

Go Explore tickets are another smartcard product that entitle the holder to unlimited travel on scheduled services on all of the island's transport network (bus and rail) except for the Manx Express bus service (Douglas-Ramsey via Mountain Road).

Child fares apply between 5 and 15 years old, or for those between 16 and 19 still in full-time education and in possession of a school card.

The ticket also entitles the holder free admission to all Manx National Heritage sites.
