Colloquially known as "zoo buses", some of the animal designs appearing on these buses were decided by vote. A giraffe print design was added to the fleet in 2021 following the opening of the zoo's giraffe house. Vehicle tracking Lothian Buses are active members of the Bustracker system and are responsible for the funding of it as well as being partly responsible for the operation of it. It operates by tracking the movements of buses; computers then relay this information to the designated bus tracker signs throughout the city giving real-time and more up-to-date information on when buses are due to the passengers. In December 2009, it was announced that following the success of Bustracker, an application had been developed for the iPhone that is similar to the way Bustracker works.

Although not developed by Lothian Buses or The City of Edinburgh Council, the application has now won the backing of both organisations. My Bus Edinburgh is an application developed for the Android platform which is similar in functionality to the iPhone application.

In August 2010, the company introduced an early running alarm system for drivers, which is linked into the automatic vehicle tracking system, and sounds an alarm and displays warning messages if the bus is running early. This was as a result of the company being fined £10,500 by the Traffic Commissioner for Scotland, having been found to be running buses early. After a customer complaint, Vehicle and Operator Services Agency monitored services 4, 16, 27 and 45 in February 2010, and found that of 303 instances, 44 buses were running early, despite starting the route on time, while 20 were running late. The company's defence was that they had built in some running time to cope with the delays due to tram works, but in some places, these works had ended early. The Commissioner accepted this defence, and chose not to take action against the company's operating licence (which
