When is it necessary to use turn signals?

Using turn signals is crucial for ensuring safety on the road as they communicate a driver's intentions to other road users. It is necessary to use turn signals when making any turning movements, changing lanes, or merging into traffic. This practice alerts other drivers and pedestrians of your intentions, allowing them to react appropriately, which helps to prevent accidents and maintain the flow of traffic.

Situations such as changing lanes or merging are particularly critical, as other drivers need to know your next move to maintain safe distances and transitions. The act of signaling is part of responsible driving behavior and is essential in promoting a cooperative driving environment.

In certain scenarios, not using turn signals can lead to confusion and may result in dangerous situations for everyone on the road. While different jurisdictions might have specific laws regarding signal use, the general rule of thumb is to signal any time your actions may impact other road users.
