Alberta Written Drivers Learners Test Practice

Using turn signals is crucial for safe driving as their main purpose is to communicate your intentions to other road users. This communication is essential for maintaining safety on the road, as it allows other drivers, pedestrians, and cyclists to understand what actions a driver is about to take, such as turning or changing lanes. By effectively signaling, drivers can help prevent accidents that may occur due to misunderstandings or unexpected moves.

The other options do not address the primary purpose of turn signals. Indicating the end of a lane pertains more to lane markings and road signs rather than personal vehicle communication. Signaling a speed change is typically managed through other types of road signs or vehicle behaviors, while warning of obstacles ahead is more aligned with hazard lights or caution signals rather than turn signals. Thus, the correct choice underscores the importance of driver communication in ensuring everyone on the road can anticipate and react accordingly to potential movements and decisions made by one another.
