What is the correct action to take when preparing for a left turn?

When preparing for a left turn, performing a head check over your left shoulder is essential for ensuring safety. This action allows the driver to check for any vehicles, cyclists, or pedestrians that may be coming from behind on the left side, which might not be visible in the mirrors. It is a critical step in identifying any potential hazards before executing the turn.

In addition to the head check, it is also important to signal appropriately and be aware of the surroundings. This step improves overall situational awareness and helps to prevent accidents at intersections. While signaling is important, simply looking straight ahead or proceeding without signaling does not adequately prepare the driver for a safe maneuver. Ignoring these steps can lead to dangerous situations or misunderstandings with other road users.
