What is the recommended gap when turning left to join traffic?

When turning left to join traffic, it is important to ensure that there is a sufficient gap to safely merge into oncoming vehicles. The recommended gap for turning left is indeed greater than when turning right. This is primarily because turning left typically involves crossing oncoming lanes of traffic, which poses an increased risk of collision.

When turning right, the driver usually merges into traffic moving in the same direction, allowing for a relatively shorter gap since the flow of traffic is compatible. Conversely, when making a left turn, the driver must assess the speed and distance of oncoming vehicles, ensuring that they have enough space to navigate safely without impeding the flow of oncoming traffic.

Therefore, it's essential to allow for a greater gap when turning left to provide enough time to execute the turn safely, accounting for potential speed differences and the need to clear oncoming vehicles.
