What is the first thing a driver should do after deciding to make a turn?

After deciding to make a turn, signaling at least 100 feet from the turn is crucial for ensuring safety on the road. This action communicates the driver's intentions to other road users, including pedestrians, cyclists, and other vehicles. By signaling early, the driver allows sufficient time for others to react accordingly, which helps prevent accidents and promotes smoother traffic flow.

Signaling informs other drivers of the upcoming maneuver, enabling them to adjust their speed or position as necessary. This practice is not only a legal requirement in many jurisdictions but also a fundamental aspect of safe driving behavior. It enhances situational awareness and fosters cooperation among road users.

While checking mirrors, changing lanes, and slowing down are important aspects when preparing for a turn, they should occur in conjunction with or after signaling. Proper signaling is the first step and sets the stage for all subsequent actions needed for a safe turn.
