At what speed must you drive in a business district unless otherwise posted?

Driving at a speed of 25 mph in a business district is established as a default speed limit in many areas, including Michigan, unless additional signage indicates otherwise. This speed limit is set to ensure the safety of pedestrians and to accommodate the increased volume of vehicles and foot traffic typically found in business districts. Lower speed limits help to reduce the severity of potential accidents and allow drivers more time to react to unexpected situations, such as pedestrians crossing streets or vehicles entering or exiting driveways.

In contrast, other options present speeds that may be deemed too high for such environments where safety is of utmost importance. People conducting business, shopping, or attending to other activities expect a safer and more controlled traffic environment in these areas.
