How should a driver signal their intention to join the traffic?
Joining traffic
Explanation
To merge into traffic, it is important to **notify other drivers** of the maneuver you are going to perform. This is done using the **corresponding turn signal**, which is the proper way to indicate a lane change, direction, or turn.
- **Turn signal**: You must turn on the signal light on the side to which the vehicle is going to move. This allows other drivers to know where the vehicle is heading and to act accordingly.
- **Use of lights**: The lights must be on for the entire duration of the maneuver and turned off once it is completed. This ensures that the signaling is clear and visible to all road users.
- **Alternative with the arm**: Although you can use your arm to signal, the vehicle's lights are the most common and effective method to indicate the intention to merge into traffic.
The use of the **horn** or **brake lights** is not appropriate for signaling the intention to merge into traffic. The horn is used to warn of a danger, and the brake lights indicate that the vehicle is slowing down. Therefore, the correct option is to use the **corresponding turn signal**.
