#1. If you are traveling in lane B (beneath a steady yellow X), you must:

Lane-use control signals show how specific lanes of a street or highway should be used. A steady yellow X over a traffic lane means that you must change lanes. Get ready to leave the lane safely.


#2. What is the meaning of this sign?

This is a yield sign.

Three-sided red yield signs mean you must slow down and be ready to stop to let any vehicle, bicyclist, or pedestrian pass before you proceed.


#3. The following are true about large trucks, except:

It is not true that they need less room to maneuver.

Generally speaking, the bigger trucks are the more room they need to maneuver.


#4. When a traffic signal is showing a flashing red light, you must:

A flashing red light has the same meaning as a stop sign. You must come to a complete stop. Then, look both ways, and proceed only after the intersection is clear.


#5. When must you use your headlights?

State law requires drivers to use their headlights:

  • When they cannot see because of insufficient light on gray days or in heavy traffic when their vehicle may seem to blend in with the surroundings.
  • When there are unfavorable atmospheric conditions, including rain, snow, sleet, hail, fog, smoke, or smog. In bad weather, use only low beams. High beams actually reduce visibility under these conditions.
  • When they cannot see pedestrians or vehicles on the highway for a distance of 1,000 feet ahead of the vehicle they are operating.
  • Between sunset and sunrise.
  • When driving through work zones.
  • Anytime your vehicle’s wipers are in continuous or intermittent use due to weather conditions.

#6. The most effective thing you can do to reduce your risk of getting injured or killed in a traffic crash is:

Injury prevention in a crash depends mostly on wearing your seat belt properly, having your head restraints properly adjusted, having an airbag in your vehicle and being positioned at least ten (10) inches away from your air bag.


#7. A broken yellow center line:

Keep to the right of a yellow center line. You may cross the broken line when passing another vehicle or when the right half of the roadway is closed to traffic. But you may only cross when it is safe to do so.


#8. If you see this sign ahead, it means:

The Do not enter sign tells you that the road or street ahead is for one-way traffic traveling in the opposite direction. When you see this sign, do not drive onto that street


#9. An orange and red sign attached to the back of a vehicle means:

Slow-moving vehicles have an orange/red triangle on the back. In rural areas, an orange triangle is displayed on the back of farm tractors and horse-drawn vehicles designed to operate at 25 mph or less. This is a slower speed than traffic normally travels. In certain areas of Pennsylvania, it is not at all unusual to find yourself sharing the road with farm tractors and horse-drawn vehicles. Stay a safe distance back, and do not honk to pass.


#10. You can park and leave your car:

As long as your vehicle is clearly visible, you can park on a hill.

Never park or leave your vehicle on a bridge, on a crosswalk or within 30 feet of any flashing signal, stop sign, yield sign or traffic control device located at the side of a roadway.


#11. You are on a two-lane roadway with a center turn lane. You approach a school bus with flashing red lights that has stopped on the other side of the road. You must:

When a school bus stops and its red lights are flashing and its stop arm is extended, you must stop at least 10 feet away from the bus, whether you are behind the bus, coming toward it on the same roadway or approaching an intersection at which the school bus is stopped. Remain stopped until the red lights stop flashing, the stop arm has been withdrawn and the children have reached a safe place.

There is only one exception to the school bus stopping requirement. If you are approaching a school bus that is stopped with its red lights flashing and stop arm extended and you are driving on a separate roadway or the opposite side of a divided highway, you do not have to stop.

Separate or divided roadways are roads that are divided by physical barriers such as metal median barriers (guide rails), concrete median barriers, and non-mountable curbs.


#12. Breaking into the line of a funeral procession is:

If your see a funeral procession on the road, yield to vehicles in the procession. Once the lead vehicle has cleared an intersection, the rest of the procession has the right-of-way. Allow the procession to pass and do not cut in and out of the procession unless you are directed otherwise by a police officer or an agent or employee of the funeral director during a funeral.


#13. This sign means:

The flagger ahead sign warns drivers that there is a flagger ahead that will be controlling traffic. Proceed with caution.


#14. Avoid passing another vehicle:

Passing other vehicles calls for good judgment. You must always make sure passing is allowed, and that you can pass safely.

You may not pass:

  • When you are within 100 feet of or are crossing any intersection or railroad grade crossing, unless an official traffic control device says you may.
  • When you are within 100 feet of any bridge, elevated structure or tunnel because these may block your view.
  • When you are approaching or are on a curve or a crest (top) of a hill on a two-lane road if your view of oncoming vehicles is blocked.

#15. To stop in an emergency situation with an Anti-Locking Brake System, you need to:

The correct way to stop quickly with conventional brakes is to pump the brakes. Drivers with ABS need to maintain firm and continuous pressure on the brake.


#16. Why should you allow more space in front of your vehicle when following a large truck?

Allow a longer following distance than usual when you are following a large vehicle blocking your view ahead. You need extra room to see around the vehicle.

Remember, drivers of trucks, buses, vans, or cars pulling campers or trailers often have large blind spots directly behind them. They may slow down suddenly without knowing you are behind them.


#17. Does a posted speed limit of 65 mph mean that you may always drive 65 mph on that highway?

Speed limits are maximum limits to be traveled only when driving conditions are ideal. When the road is wet or slippery, when you cannot see well or when anything else makes conditions less than perfect, drive below the posted speed limit. Even if you are driving within the posted speed limit, you can still be ticketed for driving too fast for conditions.


#18. If you have a tire blowout while driving, you should:

If you have a flat or blowout:

  • Hold the steering wheel tightly.
  • Stay off of your brake! Braking after a blowout will cause you to skid and lose control of your vehicle.
  • Slowly take your foot off the gas pedal and let the car come to a stop.
  • Steer where you want to go, but steer smoothly – do not make large or jerky steering actions.

What You Should Know about This Written Test Practice

Questions are drawn from a pool of more than 500 test questions, which should be enough to help you pass your knowledge exam the first time.

All questions relate to the information in the Pennsylvania Driver’s Manual and official test questions, which means that you don’t study anything that cannot turn up on your real examination.

Remember to always start by getting a copy of the manual. You can get a hard copy from any Driver Licensing office or your driving school. You can also download a PDF-version from the DMV website .

Read the manual to get an overview of everything you need to learn. Somethings you already know, like some of the most common road signs, other things are new.

With this practice test, you can check what you already master and what you should study some more.

You can take the practice test over and over again. It will look different every time you take it.

Feedback plays an important role when you learn through practicing. With this sample test, you will get instant feedback after each question. It will tell you if your answer is correct or not. When you miss a question, there is also a short text to help you understand the correct answer.

The Real Pennsylvania Written Test

The knowledge exam in Pennsylvania has 18 questions. You need 15 correct answers to pass the examination, which means that the passing score is higher than in many other states .

What is on the PA DMV Test?

This is what the law says about the traffic laws exam:

“…a test of the applicant’s ability to read and understand official traffic-control devices, knowledge of safe driving practices and the traffic laws of this Commonwealth.”

There is also at least one question about alcohol or drug use on the test:

“…The traffic laws examination shall contain at least one question relating to the driver’s ability to understand the effects of alcohol and drug use on highway safety or the provisions of section 1547 (relating to chemical testing to determine amount of alcohol or controlled substance)….”

Expect 2-3 questions about common road signs, including their shapes and colors. All signs you need to learn are described in the PA Driver’s Manual.

Is the Pennsylvania Written Test Hard?

Hard - DMV Test difficulty grading by licenseroute

18 questions and a passing score of more than 83% give very little room for mistakes. This also shows in the unofficial failure rate on the PA DMV permit test. Among first-time test takers almost 1 out 2 fail the exam.

Surveys also show that the younger a test taker is, the higher the risk of failing the first time. Failure rate is also a result of how much time a test taker spent on preparing for the exam.

Perhaps more interesting is that the use of practice test is important for the chances of passing the exam the first time. Among those who successfully passed, more than 90% had used practice tests while they studied. Among those who failed, only 20% had used online practice tests.
