1. A traffic light is green, but a police officer at the intersection signals for cross traffic to proceed instead. What should a driver facing the green light do?

Proceed on the green light, since traffic signals take precedence over hand signals
Follow the officer's directions, since an officer's orders override the signal
Stop and wait until the officer leaves the intersection
Proceed only if no cross traffic is visible

Answer: B — Follow the officer's directions, since an officer's orders override the signal

A police officer can overrule signals, and officers' orders must always be obeyed, even when they conflict with the light.

2. In a standard vertical traffic signal, which light is positioned at the top?

Red
The green arrow
Green
Yellow

Answer: A — Red

In a vertical signal the lights run red, then yellow, then green from top to bottom, with any green arrow at the very bottom.

3. The signal light turns yellow just as a driver reaches a point too close to the intersection to stop safely. What should the driver do?

Brake hard and stop immediately
Continue through the intersection
Slow down and proceed with care, as at a flashing yellow signal
Stop only if pedestrians are present

Answer: B — Continue through the intersection

A yellow light means stop before entering unless the driver is too close to stop safely, in which case they should proceed through.

4. At a railroad crossing, the signal begins flashing red. When is it safe for a driver to proceed?

After stopping and waiting five seconds
As soon as the driver can see a clear track in both directions
Only once the lights stop flashing and all warning devices have deactivated
Once the gates begin to rise, even if the lights are still flashing

Answer: C — Only once the lights stop flashing and all warning devices have deactivated

A flashing red at a railroad crossing means a train is coming; a driver goes only when the lights stop and all warning devices deactivate.

5. A pedestrian is midway across an intersection when the signal changes to a steady raised palm. What should the pedestrian do?

Immediately turn back to the curb they left
Wait where they are for the walking figure to reappear
Continue crossing to reach the other side
Stop and remain in the middle of the crosswalk

Answer: C — Continue crossing to reach the other side

The steady raised palm means not to start crossing, but anyone already in the crosswalk finishes crossing.

6. A driver notices an orange, diamond-shaped sign ahead. What kind of information does it warn about?

An upcoming no-passing zone
Construction or road-maintenance activity ahead
A posted speed regulation
A roadway hazard such as an animal crossing or curve

Answer: B — Construction or road-maintenance activity ahead

Orange diamonds are road work signs warning of construction and maintenance activity such as lane closings and flaggers.

7. A yellow, diamond-shaped sign with a black symbol appears along a road. What is it warning about?

An upcoming no-passing area
An active construction or maintenance zone
A posted maximum speed
A general roadway hazard, such as a curve, deer crossing, or railroad crossing

Answer: D — A general roadway hazard, such as a curve, deer crossing, or railroad crossing

Yellow diamonds are warning signs with black symbols covering road conditions, deer, railroad and school crossings, and curves.

8. A flagger in a highway work zone signals a driver to stop, though no stop sign is posted there. Must the driver obey, and what happens to fines for violations in that zone?

No, flaggers apply only after dark, and fines are doubled only at night
Yes, the flagger has the authority of a regulatory sign, and fines are doubled in work zones
No, flaggers only advise; the driver may proceed with caution, and fines are unchanged
Yes, but only construction vehicles must obey the flagger, and fines are unchanged

Answer: B — Yes, the flagger has the authority of a regulatory sign, and fines are doubled in work zones

A flagger has the authority of a regulatory sign, and all fines are doubled in work zones.

9. A curve ahead is sharper than most, and the posted speed limit is not safe for that particular curve. What does the additional plaque mounted below the curve warning sign show?

A lower, advisory speed safe for the curve
The distance remaining to the curve
The legal speed limit for the whole road
A reduced speed limit that is legally enforceable like a posted limit

Answer: A — A lower, advisory speed safe for the curve

When a curve's safe speed is below the posted limit, an advisory speed plaque accompanies the warning sign to show that lower safe speed.

10. A driver wants to pass a slower vehicle. The lane marking on the driver's own side of the center line is solid, while the opposing side is dashed. Is passing allowed?

No, but only if the vehicle ahead is a truck
No, a solid line on the driver's own side forbids passing
Yes, because the opposing side is dashed
Yes, if the road is a divided highway

Answer: B — No, a solid line on the driver's own side forbids passing

Passing is governed by the line on your own side: a solid line on your side forbids passing regardless of the other side's marking.

11. A driver traveling alone sees a white diamond painted on the pavement of the leftmost lane, with a nearby sign showing the hours it applies. What does this mean for the driver?

That lane is reserved for trucks only
That lane is reserved for buses or vehicles carrying multiple occupants

Answer: D — That lane is reserved for buses or vehicles carrying multiple occupants

White diamonds mark HOV lanes, reserved for buses or multi-occupant vehicles during posted hours.

12. A driver needs to go left at a roundabout. How is this accomplished, given that movement through a roundabout is only by right turns?

Turn left across oncoming traffic at the entrance, as at an ordinary intersection
Enter with a right turn, continue around the center island, and leave with a right turn at the chosen street
Drive around the center island in whichever direction reaches the exit sooner
Stop at the entrance and wait for a gap to cross straight through the intersection

Answer: B — Enter with a right turn, continue around the center island, and leave with a right turn at the chosen street

A roundabout is a one-way circular intersection entered and exited only by right turns, which eliminates left-turn conflicts.
