What is a common consequence of not using turn signals?

When drivers fail to use turn signals, it can lead to confusion among other road users. Turn signals are essential for communicating intentions to other drivers, cyclists, and pedestrians. When a driver does not signal a turn or a lane change, it leaves other drivers guessing about what the non-signaling driver plans to do next. This uncertainty can result in erratic movements, potential collisions, and an overall increase in the risk of accidents.

Moreover, confusion can lead to a chain reaction of mistakes from other drivers who may misinterpret the actions of those not signaling. For instance, a driver might misjudge the speed and distance of a vehicle when they do not see a signal indicating a turn or lane change, leading to sudden stops or swerving that can create hazardous situations. Thus, the lack of turn signal use compromises safety on the road and disrupts the flow of traffic.

The other options do not accurately reflect the consequences of failing to signal; increased speed limits, improved traffic flow, and the idea of having no consequences at all do not capture the critical role that signaling plays in maintaining safe driving practices.
