How can you identify a controlled intersection?

A controlled intersection is defined by the presence of traffic management devices that regulate the flow of vehicles and pedestrians. This is typically achieved through traffic lights or stop/yield signs, which provide clear instructions to drivers about when to stop, go, or yield to other vehicles or pedestrians. These devices are crucial for maintaining order and preventing collisions at busy junctions.

Recognizing a controlled intersection allows drivers to anticipate the actions they need to take, contributing to overall road safety. The presence of well-marked signs or functioning traffic signals indicates that the intersection is monitored and has specific rules that must be followed.

The other options do not define a controlled intersection. Speed bumps are primarily for slowing down traffic but don't provide controlled access. The number of vehicles present might suggest how busy an intersection is, but it does not indicate whether it is controlled or not. Roundabouts are a specific type of intersection design but are not universally applicable as a measure of control compared to traffic lights or signs. Therefore, recognizing controlled intersections is essential for safe and efficient navigation on the roads.
