Which of these is a necessary precaution when driving?

Using turn signals is essential for safe driving as they communicate your intentions to other road users. By signaling before turning or changing lanes, you provide other drivers, cyclists, and pedestrians with the information they need to anticipate your actions, helping to prevent accidents. This practice is not only a crucial aspect of defensive driving but also a legal requirement in many jurisdictions. Safe driving relies on clear communication on the road, making the use of turn signals a necessary precaution that enhances overall roadway safety.

Driving without a seatbelt, driving while distracted, and speeding in neighborhoods are all behaviors that significantly increase the risk of accidents and injuries. They contradict the principles of safe driving and impede the protective measures that should be in place when operating a vehicle.
