What should you do before making a left turn?

Signaling at least three to four seconds ahead before making a left turn is essential for notifying other drivers and pedestrians of your intention to turn. This advance warning allows nearby vehicles to adjust their behavior, keeping everyone on the road safer. Signaling also helps to prevent accidents by ensuring that other road users are aware of your movements in advance.

The practice of signaling well ahead contributes to smooth traffic flow and reduces the chance of confusion or unexpected stops. It also complies with Virginia driving laws, which require drivers to signal their intentions to change direction.

In contrast, speeding up before the turn is dangerous because it can lead to losing control of the vehicle or not being able to make the turn safely. Keeping the front wheels pointed to the left is not advisable; instead, you should maintain your vehicle's control and position until the actual moment of the turn. Lastly, checking the rear-view mirror only does not provide a comprehensive understanding of the traffic around you. It is critical to check both side mirrors and look over your shoulder as well to ensure a complete view of your surroundings before executing the turn.
