Minnesota Permit Practice Test

What does the signal of an arm extended out indicate?

1. Right turn

2. Left turn

3. Stop

4. U-turn

The correct answer is: Left turn

An arm extended straight out from the driver's side window is a hand signal used to indicate a left turn. This method of signaling is a standard practice to communicate intentions to other drivers and pedestrians, especially in situations where turn signals might not be visible. Using hand signals is crucial for safety as it provides clear and understandable messages about the direction a driver intends to go. In the context of this question, the other options do not apply to an arm extended in this manner. For example, a right turn would be signaled by an arm bent at the elbow with the hand pointing upwards. Stopping or slowing down is indicated by an arm bent at the elbow with the palm facing backward, while a U-turn typically does not have a specific hand signal associated with it and would generally rely on turning indicators. Thus, the correct interpretation of an arm extended out is specifically to signify a left turn.
