What is the default speed limit within cities and towns, unless posted otherwise?

The default speed limit within cities and towns is indeed 50 km/h unless otherwise posted. This speed limit is established to promote safety in areas with higher pedestrian activity, increased traffic, and various road users such as cyclists and children. The 50 km/h limit allows for a balance between efficient vehicle movement and the protection of vulnerable road users. It is crucial for drivers to be aware of this default limit, as it applies universally unless road signs indicate a different speed. Such regulations are in place to ensure conformity and enhance the predictability of road behavior, which is vital for road safety in urban environments.
