Arizona Driving Permit Written Practice Test

How can you tell that a driver is about to turn?

1. They will slow down abruptly

2. Their turn signals will be activated

3. They will change lane positions frequently

4. They will look in their rearview mirror

The correct answer is: Their turn signals will be activated

The best indication that a driver is about to turn is when their turn signals are activated. Turn signals are a critical part of safe driving and are specifically designed to communicate a driver's intentions to others on the road. When a driver activates their turn signals, it alerts nearby drivers and pedestrians that they plan to make a turn, allowing everyone to adjust their actions accordingly. This use of turn signals is not only a matter of safety but is also mandated by traffic laws in many jurisdictions, including Arizona. While slowing down abruptly or changing lane positions could suggest that a driver is preparing to turn, these behaviors are less reliable indicators of intention. Looking in the rearview mirror can be part of general driving responsibilities but does not provide a clear signal of an immediate turn. Therefore, the activation of turn signals is the most straightforward and reliable cue that a driver intends to change direction.
