Which driving behavior is discouraged to ensure safety?

Texting while driving is discouraged to ensure safety because it significantly distracts the driver, increasing the risk of accidents. When a driver engages in texting, they are not fully focused on the road, which can lead to slower reaction times and impaired judgment. This behavior compromises not only the driver's safety but also the safety of passengers, other vehicles, and pedestrians.

In contrast, using turn signals when changing lanes promotes safety by clearly communicating intentions to other drivers, thereby reducing the risk of collisions. Driving under the speed limit is generally considered safe as it provides a buffer against unforeseen hazards. Maintaining a full stop at stop signs is crucial for ensuring that all traffic participants can navigate intersections safely. Each of these behaviors contributes positively to road safety, highlighting texting while driving as a particularly dangerous habit that must be avoided.
