What is the correct hand signal for a left turn?

The correct hand signal for a left turn is achieved by extending the left arm straight out from the driver's side window. This hand signal is universally recognized and is a crucial part of signaling intentions to other drivers when turning. It communicates clearly that the driver intends to make a left turn, allowing other road users to anticipate the maneuver.

Using this hand signal enhances safety on the road, especially in situations where the vehicle's turn signals may not be visible, such as during a lane change in urban environments or in larger vehicles where visibility might be obstructed. Properly signaling your intentions is an important aspect of defensive driving and helps to prevent accidents by ensuring that all road users are aware of one another’s actions.
