what is speed limit on expressway
Safety [edit]. The default speed limit and National Speed Limits on Singapore expressways is 90 km/h (56 mph), but in certain areas a lower speed limit such as 80 km/h (50 mph) or 70 km/h (43 mph) is applied, especially in large urban areas, tunnels, heavy traffic and crosswinds.
You must obey the posted speed limit or, if no limit is posted, drive no faster than 55 mph. Be aware, however, that some cities in New York have speed limits lower than 55 mph that may not be posted. For example, the speed limit is 30 mph in New York City unless another limit is posted. It is important to note that the minimum speed on most expressways in the State of New York is 45 miles per hour. It is often just common sense to keep your actual speed limit well below the posted limit.
Illinois State law requires the department to establish reasonable and safe speed limits, and Public Act 098-0511 allows the maximum speed limits on Illinois interstates to be increased to 70 mph, said Miller.
