If you are in a lane marked with an arrow showing a left turn only, what must you do?

When you find yourself in a lane that has an arrow indicating a left turn only, it is mandatory to follow the direction of the arrow and make a left turn. This road marking is clear and designed to guide drivers, ensuring safety and efficiency in traffic flow. Adhering to such directional indications helps prevent confusion and potential accidents at intersections, as it creates a structured environment where all road users know what to expect from each lane.

In contrast, continuing straight, changing lanes to turn right, or stopping and waiting for instructions would not comply with the marked lane requirements. These actions could disrupt traffic and create dangerous situations, as they go against the established traffic control measures signaling what is required in that specific lane.
