On the 29th January 1900, a government ordinance limited the speed of vehicles inside settlements to the velocity of a hand-cantering horse. In 1935, speed limits inside settlements was set at 35 km/h.[1][2] Vehicles with two or more trailers were limited to 35 km/h, while trucks and buses were limited to 50 km/h. However, public buses could ask for an exception.
A law in 1950 limited the speed in thick fog to 25 km/h and at level crossings to 15 km/h.[3] An ordinance introduced in 1953 specified places where speed needs to be slow, i.e. under 15 km/h: along processions, at pedestrian crossings, while the driver is entering the road, near buses or trams, near work places, while the road is oily or while pedestrian traffic is dense.[4]
Law in 1960 limited speed inside settlements between 5 a.m. and 11 p.m. to 50 km/h. A speed of buses and trucks over 3500 kg were limited to 80 km/h.[5] Also, in 1966, motorcycles were limited to 80 km/h. Long-distance buses are freed from limit. Towed automobiles were limited to 50 km/h.[6]
Speed limits were abolished on motorways (dálnice), even for trucks, in 1971.[7] Furthermore, in 1975, all of the 50 km/h limits were increased to 60 km/h. The special limits for motorcycles, trucks and buses were repealed.[8] The ordinance in 1979 was the first to limit speeds outside of settlements. Cars were limited to 90 km/h (110 km/h on motorways), long-distance buses to 90 km/h, motorcycles and trucks under 6000 kg to 80 km/h, trucks over 600 kg and buses to 70 km/h. The limit of 60 km/h (only between 5:00 and 23:00) was kept for roads inside settlements.[9]
A limit of 90 km/h (110 km/h on motorways) was established in 1989 for vehicles under 3500 kg and for buses. Furthermore motorcycles were limited to 90 km/h and all of the others motor vehicles were limited to 80 km/h. The speed inside settlements was limited 60 km/h (80 km/h on motorways), including at night. Specially signed pedestrian zones and house zones was introduced with a 20 km/h limit.[10]
Ordinance No. 223/1997 Sb., which took effect on October 1, 1997, reduced settlement limit to 50 km/h and increased the motorway limit to 130 km/h, including for motorcycles.[11]
