What is the maximum speed limit in urban areas unless otherwise posted?

Answer: C — 50 km/h

The maximum speed limit in urban areas, unless otherwise posted, is set at 50 km/h. This limit is established to promote safety in environments where there are typically higher pedestrian activities, cyclists, and other vehicles. A speed limit of 50 km/h allows drivers to maintain better control of their vehicles and provides adequate reaction time to respond to sudden changes in traffic conditions, such as pedestrians crossing the street or vehicles making unexpected stops. In urban settings, the concentration of people and different forms of transportation means that higher speeds can lead to more severe accidents. Therefore, this standard limit strikes a balance between efficient transportation and safety for all road users. In cases where the posted speed limit is lower or higher, it reflects specific conditions of the area, like construction zones or highways, where different rules apply.
