When should a driver signal their intentions?

Signaling intentions is a crucial aspect of safe driving, especially for drivers of combination vehicles. The correct approach is to signal at least 100 feet before making a turn or changing lanes. This advance notice is important because it gives other drivers and pedestrians time to react and adjust their movements accordingly. Proper signaling enhances safety on the road by reducing confusion and minimizing the risk of accidents.

In addition, signaling early allows the driver to communicate clearly their intentions, which is particularly vital in highway settings or busy urban areas where other road users might not be able to anticipate the driver's maneuvers. This practice aligns with traffic regulations and promotes a more predictable traffic flow, which is especially important for larger vehicles that require more time and distance to stop or change direction.

Other options suggest incorrect timing or limited circumstances for signaling, which could lead to misunderstandings on the road and increase the likelihood of accidents. For instance, signaling only when changing lanes or in heavy traffic situations could leave other road users unprepared for the driver's actions, undermining overall road safety.
