What should you signal your intention to do when driving?

Signaling your intention to change lanes or turn is crucial for safe driving. This action communicates your plans to other drivers and pedestrians, helping to prevent misunderstandings and potential accidents. For instance, when you use your turn signal before a lane change or turn, it allows other road users to anticipate your movements, which contributes to smoother traffic flow and enhances safety on the road.

While it might seem beneficial to signal when you are speeding up or slowing down, these actions often do not require a signal as they don't involve a change in the pattern of traffic or your vehicle's position on the roadway. Similarly, signaling when parking or leaving the road is generally unnecessary unless it involves a turn or lane change. Lastly, driving in reverse typically does not require a signal, although caution is still necessary and you should check for obstacles or pedestrians before reversing. Therefore, signaling your intention to change lanes or turn is the most critical and relevant action to ensure communication and safety while driving.
