USAREUR Practice Exam

For which actions must a driver use the turn indicator?

1. Only to pass another vehicle

2. Only to change lanes

3. Only when exiting a traffic circle

4. All of the above

The correct answer is: All of the above

Using turn indicators is essential for driver communication on the road, as it allows other road users to anticipate a driver's intentions. This practice enhances safety and reduces the chance of accidents. When passing another vehicle, a driver is required to signal to inform others of the intent to maneuver around the vehicle. This indication helps maintain safe distances and allows surrounding vehicles to adjust their speed or position accordingly. Additionally, signaling while changing lanes is crucial for indicating a shift in position to other drivers. It alerts others to potential changes in traffic flow and helps prevent collisions that could occur if another driver is unaware of the lane change. When exiting a traffic circle, using the turn indicator serves a similar purpose. It informs fellow drivers that the vehicle intends to leave the circle, which is important for maintaining traffic order and preventing confusion about which vehicles are continuing through the intersection or exiting it. Given that signaling is important in all these scenarios, the option that encompasses them all underscores the need for consistent and clear communication through the use of turn indicators whenever a driver intends to change their path on the road.
