What is the default speed limit in business and residential districts without any signs posted?

The default speed limit in business and residential districts without any signs posted is 50 km/h. This limit is established to promote safety and provide a guideline for drivers in areas where pedestrian traffic and other potential hazards, such as vehicles entering or exiting driveways, are common.

In business districts, a speed limit of 50 km/h allows for efficient movement of traffic while still being mindful of pedestrians and cyclists. Similarly, in residential areas, this limit balances the need for efficient vehicle flow with the safety considerations for residents, particularly children who may be playing near the roadside.

It's important to note that these default speed limits are in place due to the higher density of activity in these zones, making it crucial for drivers to adjust their speed to the conditions of the area. Additionally, local jurisdictions may have specific regulations or lower limits posted to enhance safety, so drivers should always remain vigilant and aware of their surroundings.
