What must drivers entering an intersection to turn left ensure?

When drivers are preparing to turn left at an intersection, they must ensure that they do not enter the intersection unless they can do so without stopping. This is crucial for several reasons. Firstly, waiting in the intersection while trying to turn left can obstruct oncoming traffic and pose a safety risk to both the driver and other road users. It can lead to confusion and potential collisions, especially if the light changes.

Additionally, entering an intersection only when there is enough space to complete the turn minimizes the chances of being caught in a situation where the traffic signal changes or where obstacles may suddenly appear. This ensures that the driver can execute the turn safely and efficiently, maintaining the flow of traffic.

The requirement to avoid entering an intersection if they cannot clear it is a fundamental principle in traffic safety and reflects the responsibility of drivers to be aware of their surroundings and the current traffic conditions.
