What is the first step a driver should take after deciding to turn?

Answer: B — Signal at least 100 feet from the turn

The first step a driver should take after deciding to turn is to signal at least 100 feet before making the turn. This action communicates to other drivers and pedestrians that you intend to change direction, enhancing safety for everyone on the road. Signaling is a critical part of driving etiquette and traffic regulations, allowing others to anticipate your actions and adjust accordingly. While other actions, such as checking for pedestrians or adjusting speed, are also important in the turning process, initiating the turn with a signal is the primary step to ensure awareness among surrounding road users. This establishes clear communication on the road, promoting a safer driving environment. Familiarizing oneself with proper signaling practices can significantly reduce the likelihood of accidents while turning.
