Question

which of the following are areas for turning that are controlled by a signal or sign?
protected left turn
unprotected left turn
unprotected right turn
all of the above

Explanation:

A protected left turn uses dedicated traffic signals (green arrows) to control the turn, separating turning traffic from oncoming traffic. Unprotected left turns rely on standard traffic signals (green lights) and right-of-way signs to guide drivers, as they must yield to oncoming traffic. Unprotected right turns are controlled by traffic signals (e.g., turning on a red light where permitted, following stop signs or traffic light indications) and signs that outline right-of-way rules. All these turn types are managed by signals or signs.

All of the above
