🛑 SECTION 1: INTERSECTIONS & RIGHT-OF-WAY (The High-Failure Zone)
Q1. You are approaching an intersection with a flashing red traffic light. What must you do? A: Stop completely. Treat it exactly like a STOP sign. Look all ways and yield to traffic and pedestrians before proceeding.

Q2. You have a solid green light, but traffic on the other side of the intersection is backed up and blocking your path. Should you enter the intersection? A: No. Do not enter an intersection if you cannot get completely across before the light turns red. Blocking an intersection ("gridlock") is illegal.

Q3. Two vehicles arrive at a four-way stop at the exact same time. Who has the right-of-way? A: The vehicle on the right.

Q4. You are approaching a corner where pedestrians are crossing in an unmarked crosswalk. You must: A: Yield the right-of-way to the pedestrians. Every corner is a crosswalk, whether lines are painted or not.

Q5. You arrive at a "T" intersection without Stop or Yield signs. You are on the road that ends. Who must yield? A: You must yield to cross traffic on the through road.

Q6. You are waiting to turn left at a solid green light (no arrow). What must you do? A: Yield to all oncoming traffic and pedestrians. Only turn when it is safe and clear.

Q7. You hear a siren and see an emergency vehicle approaching from behind with flashing red lights. What should you do? A: Pull over to the right edge of the road as soon as it is safe and stop until the vehicle passes.

Q8. You see a school bus stopped on the opposite side of a divided highway (separated by a concrete barrier) with red lights flashing. Do you need to stop? A: No. You do not need to stop if the highway is divided by a separate roadway or physical barrier.

Q9. What does a solid red arrow signal mean? A: Stop. You are not allowed to turn in the direction of the arrow until a green signal appears. (No "right on red" for red arrows).

Q10. What do double solid yellow lines in the center of the road mean? A: They indicate a barrier. You may not cross them to pass or drive to the left of them, except to turn left into or out of a driveway or private road.

Q11. What is the purpose of a center lane marked with solid yellow lines on the outside and broken yellow lines on the inside? A: A center left-turn lane. Use it only for making left turns or U-turns, not for regular travel or passing.

Q12. You see white diamond markings on the pavement in the far-left lane. What does this indicate? A: It is a High-Occupancy Vehicle (HOV) or "carpool" lane.

Q13. What does a curb painted RED mean? A: No stopping, standing, or parking at any time.

Q14. What does a yield sign (inverted triangle) mean? A: Slow down, be ready to stop, and give the right-of-way to other traffic and pedestrians.

Q23. Are bicyclists allowed to use the same travel lanes as motor vehicles? A: Yes. Bicyclists have the same rights and responsibilities as vehicle drivers.

Q24. Why should you increase your following distance behind a motorcycle? A: Motorcycles can stop much faster than cars, and they are easily hidden in blind spots.

Q25. You are approaching an intersection and a large truck ahead of you is signaling for a right turn. What should you expect? A: The truck may need to swing wide to the left to complete the turn. Do not squeeze between the truck and the curb.
