 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 45 , 27 , 4 and 16 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 authorises a maximum of 700 vehicles ) . Instead the Commissioner imposed a fine set much lower than the legal maximum ( calculated as £ 550 * 700 vehicles = £ 385 @,@ 000 )
