How can you tell if a driver intends to turn left at an intersection?

When a driver intends to turn left at an intersection, they will typically use their left turn signal to indicate their intention to other road users. This is a crucial part of safe driving etiquette and communication on the road. Signaling not only informs other drivers of their plans but also helps pedestrians and cyclists understand the driver's actions, promoting safety and reducing the risk of accidents.

While slowing down or changing speed could indicate a driver is preparing to make a turn, they are not definitive signs of a left turn specifically. Similarly, looking to the right may be a part of checking for oncoming traffic before turning, but it does not necessarily indicate intent to turn. Proper signaling is the most clear and recognized method for showing intent to turn left, making it the most reliable indicator in this scenario.
