What is the speed limit in residential areas unless otherwise posted?

In residential areas, the speed limit is typically set at 20-30 kilometers per hour unless posted otherwise. This limit is designed to enhance safety for pedestrians, children playing, and cyclists who may be sharing the road. The lower speed allows drivers more time to react to unexpected situations, which is particularly important in areas where there may be frequent stops for pedestrians crossing or vehicles entering and exiting driveways.

Higher speed limits, such as those in the other provided options, would pose a greater risk to residents and could lead to more severe accidents. Therefore, the designated limit of 20-30 kilometers per hour emphasizes the importance of cautious driving in community settings where interactions with non-motorized road users are more common.
