When turning left to join traffic, what should the gap to the left be compared to turning right?

When turning left to join traffic, the gap to the left should be less than when turning right. This is because when making a left turn, drivers often must cross oncoming traffic, which requires a more substantial gap to ensure safety. However, when turning right, typically, the path is clearer, and there may not be oncoming vehicles in the same way, allowing for a smaller gap.

Drivers need to assess the speed and distance of approaching vehicles, ensuring they have enough space to safely merge into traffic when turning left. The left turn requires careful judgment of the traffic flow as it can involve more complexities including not just the vehicles immediately next to them but also those in the opposite lane. In contrast, right turns usually involve less traffic conflict, allowing for a smaller gap requirement.
