Before traffic lights were built in Estonia, traffic was manually regulated by the police. On the 1st of April 1929, Anton Arumäe was appointed Tallinn’s first traffic police officer. It took the police considerable time to acquire the necessary skills and experience to carry out this role. For a long time, speed was estimated by eye only, and later measured using a stopwatch and special speed charts. Traffic accidents were an inevitable part of the rapidly developing traffic environment.
Speeding was often cited as the primary cause of accidents. However, the speed limit was quite low; passenger cars and motorcycles were not permitted to exceed 25 km/h in the city centre.
One of the major issues police had was frequent drunk driving. The streets of the Old Town, particularly the narrow section of Viru Street, Town Hall Square, Nunne and Mündi streets were considered very dangerous. Many accidents also occurred on Pärnu maantee, which experienced heavy use by people from rural areas.
The first red, yellow and green traffic light in Tallinn was installed in 1947 at the intersection of Pärnu maantee and Suur-Karja tänav. The first pedestrian traffic lights in Tallinn were introduced in 1959. They were installed at the busy intersection of Pärnu mnt, Estonia pst and Freedom Square.
