Observing speed limits will save you from trouble with traffic authorities. Always pay attention to the speed signs as they override other traffic regulations. Motorists must keep it 30 km/h (18 mph) in school and residential zones; 50 km/h (30 mph) in urban areas; 80km/h (50 mph) on regional roads, and 100km/h (62 mph) on national roads. For those who like cruising, you should be at most 120km/h (74 mph) on motorways. You may drive slower than the stipulated speeds during rush hours and on windy days. Search rental cars on KAYAK
