When directing traffic in an intersection, what should be followed to ensure smooth traffic flow?

1. Random signal patterns

2. Manual hand gestures

3. Typical traffic signal patterns

4. Whistle signals

The correct answer is: Typical traffic signal patterns

Following typical traffic signal patterns is crucial for ensuring smooth traffic flow at an intersection. These established patterns provide drivers with predictable signals that indicate when to stop and when to proceed, making it easier for them to navigate through the intersection safely and efficiently. Uniformity in traffic signals minimizes confusion and enhances overall safety by allowing drivers to react appropriately to the visual cues they are accustomed to. In contrast to typical traffic signal patterns, random signal patterns could create uncertainty among drivers, leading to potential accidents or traffic jams. Manual hand gestures may be useful in specific circumstances but lack the consistency and clarity of established signal patterns, which could confuse drivers unfamiliar with the particular gestures being used. Whistle signals, while they can help in some scenarios, are less reliable as a primary method for directing traffic, as they can be overlooked or misinterpreted, especially in noisy environments. Therefore, adhering to typical traffic signal patterns is the most effective way to maintain order and safety at intersections.
