Fifteen video surveillance cameras are being installed on Bulgaria's main roads, mainly on the Sofia-Varna and Sofia-Bourgas routes, Bulgarian National Television said on December 4 2009.

The cameras will be moved from place to place, to avoid motorists getting used to their being fixed in certain locations and reducing speed only at those spots.

Two such cameras are already in use in Sofia, and reportedly detect between 100 and 150 breaches of motoring laws every hour.

Traffic police said that the speed cameras reduce the risk of corruption and save time in the process of getting fines paid.
