You face a steady circular red light and no sign prohibits a right turn. What must you do before turning?
Correct answer: Stop completely, yield to conflicting traffic and pedestrians, and turn only when safe.
A permitted turn on red still requires a full stop and yielding. It is not a priority movement.

You are on a one-way street turning left onto another one-way street. The light is steady circular red and no sign prohibits the turn. What does the handbook allow?
Correct answer: Turn after a complete stop and after yielding to cross traffic and pedestrians.
The handbook expressly allows this one-way-to-one-way left turn after stopping and yielding, unless prohibited. This question does not extend the rule to other street layouts.

Your right-turn lane faces a steady red arrow. What should you do?
Correct answer: Remain stopped; do not turn in the arrow's direction while it stays red.
A steady red arrow prohibits the indicated turn until a signal indication allows movement. It differs from an ordinary permitted turn on circular red.

A light changes from green to steady yellow before you enter the intersection, and you can stop safely. What should you do?
Correct answer: Stop before entering the intersection.
Yellow warns that red is coming. Stop when you can do so safely; if already in the intersection, clear it safely.

A signal flashes red toward you. What is required?
Correct answer: A complete stop, followed by yielding and proceeding when clear.
A flashing red is a stop requirement. After stopping, yield to conflicting traffic and pedestrians before proceeding.

You approach a flashing circular yellow signal. What should you do?
Correct answer: Slow down, check for hazards and proceed cautiously.
Flashing yellow means caution, not a mandatory stop in every situation and not an assurance that the intersection is clear.

A flashing yellow left arrow is displayed while an oncoming car approaches. What should you do?
Correct answer: Yield to the oncoming car and pedestrians, then turn only when clear.
A flashing yellow arrow permits a yielding turn. It does not give the protected right-of-way of a permitted protected movement.

You want to turn left on a circular green light. An oncoming vehicle is close enough to conflict with your turn. What should you do?
Correct answer: Yield and wait for a safe opening.
A circular green does not remove the left-turn duty to yield to oncoming traffic and pedestrians.

Your light is green, but stopped traffic leaves no room for your entire car beyond the intersection. What should you do?
Correct answer: Wait before entering until enough space is available.
Do not enter unless the vehicle can pass completely through without blocking the intersection, even with a green signal.

A green left arrow is displayed beside a steady circular red. Which movement does that combination authorize?
Correct answer: The indicated left turn, when it can be made safely.
With a green arrow and steady red, the handbook allows movement only in the arrow's direction. Continue to watch for people or vehicles in the path.

All traffic signals at an ordinary intersection are out of operation. How should you treat it?
Correct answer: As a four-way stop.
The handbook specifically directs drivers to treat a nonfunctioning traffic signal as a four-way stop.

A pedestrian hybrid beacon displays two steady red lights toward you. What must you do?
Correct answer: Stop completely at the stop line and remain stopped during the steady-red phase.
The two steady red lights require a complete stop. The alternating flashing-red phase has a different stop-and-proceed rule.
