What is the typical speed range of traffic approaching intersections?

The typical speed range of traffic approaching intersections is often around 25-55 mph. This range is common because many roads that lead to intersections are designed for higher speeds, especially if they are located on suburban or urban arterial roads. Drivers typically approach intersections at these speeds unless there are specific traffic control measures in place, such as stop signs or traffic lights, which would reduce speed as vehicles near the intersection.

In this speed range, drivers have adequate time to react to obstacles, signals, or other vehicles, while also maintaining efficient traffic flow. Vehicles often decelerate as they near intersections, but the even higher speeds typical of the other options are less common, particularly in areas where intersections are prevalent, as they pose greater risks for collisions and limit the driver’s ability to make safe decisions in these dynamic situations.
