What is the recommended gap for right turns when entering an intersection?

When making a right turn at an intersection, it is crucial to ensure a safe and smooth transition into traffic. A gap of six seconds is generally recognized as an ample interval that provides enough time to assess the situation and enter the flow of traffic without causing disruption or creating a hazard. This timeframe allows a driver to evaluate the speed and distance of oncoming vehicles, ensuring that they can safely turn without increasing the risk of collision.

A two-second gap may be too short, potentially leading to rushed decisions and increased risk. Likewise, while four seconds might offer a bit more time, it's often not sufficient in busy intersections where traffic might be moving more quickly. An eight-second gap, on the other hand, could lead to unnecessary delays and disrupt the flow of traffic. Thus, a six-second gap strikes an optimal balance between safety and maintaining traffic flow.
