What should you do after joining traffic?

After joining traffic, it is important to ensure that your vehicle's turn signal is turned off. This is a crucial step to maintain safety and communicate properly with other drivers. Leaving a turn signal on after you have completed your maneuver could confuse other drivers about your intentions, potentially leading to hazardous situations.

In addition, safely integrating into traffic requires you to continue observing your surroundings. While checking your mirrors again is a good practice for situational awareness, it is not as immediately necessary as ensuring your turn signal is off, which is a direct action to prevent miscommunication. Similarly, accelerating quickly is not advisable when joining traffic, as it can lead to reckless behavior and doesn't account for the need to safely merge and maintain control of your vehicle. Yelling or making loud noises does not contribute positively to the situation and is irrelevant to safe driving practices.
