Virginia Driver's Permit Diagnostic Quiz

Virginia Driver's Permit Diagnostic Quiz (10 questions). Correct answers and explanations follow each question.

1. 1. This orange diamond sign warns of a bump in a work zone. What should you do?

   

   1. Slow down before reaching the bump. (correct)
   2. Come to a complete stop before the patched pavement.
   3. Change lanes to avoid the raised pavement.
   4. Maintain speed to cross the bump smoothly.

   Why: The sign warns that a short, abrupt rise lies ahead in the construction area, and the safest response is to slow down before you reach it so the vehicle stays stable and cargo, suspension, and following traffic aren't jolted. Drivers who trust the road habit that a bit of momentum floats a small bump, and so try to hold speed to cross it smoothly, are the ones who miss the sign's slow-down instruction.

2. 2. What does the speed shown on this advisory speed plaque tell a driver?

   

   1. The speed at which the hazard ahead can be comfortably negotiated. (correct)
   2. The maximum legal speed limit that applies through the hazard.
   3. The minimum speed drivers must maintain through the curve.
   4. The speed limit that applies only in wet or icy conditions.

   Why: An advisory speed plaque names the speed at which the hazard ahead can be comfortably negotiated, and it is a recommendation posted with a warning sign rather than a posted limit. The pull toward the legal-limit answer comes from carrying over the habit of reading any number on a roadside sign as enforceable; yellow warning signs advise, and the plaque takes its color and authority from the diamond above it.

3. 3. What does this sign tell you about the facility ahead?

   

   1. A full-service hospital with a 24-hour emergency room.
   2. Emergency medical care at a facility short of a full hospital. (correct)
   3. A highway rest area with restrooms and vending.
   4. A 24-hour pharmacy for prescription refills.

   Why: This blue sign carries a white Star of Life and marks emergency medical services ahead. It is used where medical help is available but the facility is not a full hospital, such as an ambulance station, an urgent care facility, or a trauma center. Supplemental plaques below the sign name the specific type of care offered. Drivers who reach for the hospital answer read the Star of Life as if it were the H that marks a full hospital, mixing two symbols because both belong to the same blue services family.

4. 4. A white left-turn arrow is painted in the lane you are driving in as you approach an intersection. What does it require?

   

   1. If you stay in this lane, you must turn left at the intersection (correct)
   2. You may turn left or continue straight ahead
   3. You may turn left only on a green arrow signal
   4. You may use this lane for any movement as long as you signal

   Why: A left-turn-only arrow reserves the lane for left turns, so if you remain in this lane at the intersection you must turn left. The left-or-straight answer is the trap: it carries over from the combined arrow at other intersections, whose second head points straight to permit that movement, and reads a single left head as if it worked the same way.

5. 5. What does this Be Prepared To Stop sign require of a driver approaching it?

   

   1. Reduce speed and be ready to brake because traffic ahead may stop without warning. (correct)
   2. Stop at the sign and wait for a flagger to wave you through.
   3. Merge left immediately because the right lane is closing ahead.
   4. Yield to workers and equipment entering the roadway from the shoulder.

   Why: The orange diamond warns that traffic ahead may halt without notice at a flagger, a signal, or the back of a queue. Ease off the accelerator, open up your following distance, and cover the brake so you can stop firmly if a stopped line appears around the next curve. The trap is the answer that treats the words 'prepared to stop' as an order to halt at the sign itself; a diamond flags what is coming, not the point where the driver actually stops.

6. 6. What does this Do Not Enter sign require of a driver facing it?

   

   1. Do not enter the roadway from this direction. (correct)
   2. Yield to oncoming traffic, then enter with caution.
   3. Enter only if you are a local resident or delivery driver.
   4. Enter only if driving a passenger car, not a truck.

   Why: The sign bars entry from your direction because the roadway ahead is one-way against you or is a restricted entrance; stop, back out safely, or turn around. The tempting wrong answer treats the red square like a yield, telling the driver to pause, look for oncoming, and then go if it looks clear. Yielding does not solve the problem the sign describes: any traffic on the roadway ahead is coming toward you because the roadway only runs the other way.

7. 7. A broken white line runs along the right edge of the roadway between the through lane and an exit ramp. What does it permit a driver to do?

   

   1. Change lanes across it, into or out of the auxiliary lane, when safe. (correct)
   2. Stay in the through lane; the edge line marks a hard boundary.
   3. Pass slower through traffic on the right using the auxiliary lane.
   4. Drive on the paved shoulder outside the marked lanes.

   Why: A broken white edge line marks the boundary between a through lane and an auxiliary lane like an exit ramp, and the broken pattern means you may cross it when it is safe, in either direction. A solid white edge line, by contrast, marks a crossing as discouraged, and double solid white lines mark it as prohibited. Drivers who first learned the shoulder edge line, a solid white marking the road's outer edge, often carry that 'do not cross' habit over to every white edge line and never stop to check whether this line's pattern is broken.

8. 8. What does this Police sign tell a driver?

   

   1. A police station is located ahead. (correct)
   2. A hospital is located ahead.
   3. A rest area is located ahead.
   4. An emergency telephone is located ahead.

   Why: The white POLICE legend on a blue square directs you to a police station or other law enforcement office ahead. The hospital answer reads the blue services background correctly but ignores the legend printed on the sign, which names police work, not medical care.

9. 9. You approach this No U-Turn sign and need to reverse your direction of travel. What does the sign require?

   

   1. Continue past and use a designated turnaround or another intersection. (correct)
   2. Complete the U-turn only when the road is clear of oncoming traffic.
   3. Complete the U-turn only from the leftmost lane on a green signal.
   4. Turn left here instead, since the sign forbids only left turns.

   Why: A No U-Turn sign forbids reversing direction by turning 180 degrees through this intersection or median opening, so a driver who needs to turn around continues past and uses a designated turnaround or another intersection where U-turns are allowed. Drivers who read the sign as a yield-style caution pick the answer that waits for a clear oncoming lane; the sign is a prohibition, not a caution about traffic, and a clear lane does not make the U-turn legal here.

10. 10. What does this Divided Highway Begins sign tell a driver about the road ahead?

    

    1. Two same-direction lanes ahead merge into a single travel lane.
    2. The road splits into two separate one-way roadways separated by a median. (correct)
    3. The divided highway ends ahead and traffic returns to two-way.
    4. The road ahead ends at a dead end with no through route.

    Why: The sign warns that the road splits into two separate one-way roadways separated by a median or barrier, so from that point you keep right of the divider and treat each direction as its own one-way street. The trap is the choice that reads the sign as the divided highway ending and traffic returning to two-way; that meaning belongs to the mirror-image W6-2 sign, whose symbol on the same yellow diamond points the opposite way.
