Pennsylvania Road Signs: PennDOT Exam, 15 mph Zones & Work Zone Law

Is it required to turn on headlights in a Pennsylvania work zone? What is the school zone speed limit in Philadelphia, Pittsburgh, or Allentown? What happens to your license if you pass a school bus in Pennsylvania? PennDOT administers an 18-question learners permit test. 15 correct required. Pennsylvania law requires headlights on in work zones. School zones cap at 15 mph when zone lights are flashing. School bus violations: automatic 60-day license suspension. Forcing a cyclist off the road can mean criminal charges.

1. Pennsylvania PennDOT 18-Question Test and Why Forcing a Cyclist Off the Road Can Mean Criminal Charges

Pennsylvania roads connect Philadelphia urban grid, the Pennsylvania Turnpikes mountain crossings, Pittsburgh river valley interchanges, and the rural routes of Appalachian Ridge country. PennDOT administers a three-part license process: vision test, knowledge test (18 questions, 15 correct required), and road test. Fail the knowledge test. retake the next business day. The learners permit application is valid for one year. Visit a Driver License Center near you or go to penndot.gov.

2. Pennsylvania Sign Shapes: What PennDOTs 18-Question Knowledge Test Covers About Colors and Categories

Pennsylvania driver manual covers road signs from the perspective of all vehicles. bicycles, horse-drawn vehicles, and motor vehicles are all subject to the same sign laws. On the Pennsylvania Turnpike, Pocono Mountain routes, and Philadelphia dense urban corridors, sign shape and color identify a category before text is readable. Know every row here before your PennDOT knowledge test.

Shape	Diagram	Meaning	Example Sign
Octagon (8-sided)		STOP. always and only
Triangle (inverted)		Yield to other traffic
Diamond		Warning - hazard ahead
Rectangle (vertical)		Regulatory - rules of the road
Rectangle (horizontal)		Guide or informational
Pentagon (5-sided)		School zone or crossing - exclusively
Round (circle)		Railroad crossing advance warning - exclusively
Pennant		No passing zone - exclusively
Orange (any shape)		Construction and work zone warnings
Blue (any shape)		Motorist services - gas, food, lodging, hospitals
Brown (any shape)		Recreation areas, parks, and scenic routes

3. Pennsylvania Regulatory Signs: Point Violations, 60-Day Suspensions and Criminal Charges for Forcing Cyclists Off the Road

Regulatory signs carry legal force under the Pennsylvania Vehicle Code. violations add points to your record.

6. Pennsylvania Traffic Signals: Amber Bus Lights Mean Prepare to Stop: and What the PennDOT Test Covers

Flashing red = stop sign. Flashing yellow = yield. The PennDOT knowledge test covers all signal types: standard lights, arrow signals, flashing signals, and pedestrian signals. School bus amber lights mean you MUST prepare to stop. this is a legal requirement in Pennsylvania, not just a suggestion.

Standard Traffic Lights

Steady Red

Come to a complete stop behind the stop line. Wait until green.

Steady Yellow

Prepare to stop. the light is about to turn red. Do not speed up to beat it.

Steady Green

Proceed if the intersection is clear. You must still yield to pedestrians and cross traffic.

Green Arrow (left)

You may proceed only in the direction of the arrow. Oncoming traffic is stopped.

Yellow Arrow (no left)

The protected turn is ending. Prepare to stop or yield if you have not yet entered the intersection.

Red Arrow (no left)

Do not turn in the direction of the arrow. Wait for a green arrow or green light.

Green. no left arrow

Proceed straight or right. left turn not permitted on this phase.

Opposing Traffic Extended Green

Oncoming traffic has an extended green phase. wait before turning left.

Flashing Signals

Flashing Red

Treat as a STOP sign, come to a complete stop, then proceed when safe.

Flashing Yellow

White walking figure = pedestrians may cross. Orange hand = do not start crossing; if already crossing, finish quickly.

Flashing Orange Hand + Countdown

Crossing phase is ending. Pedestrians who have started may finish; others should not begin.

Key test point: Flashing red = stop sign. Flashing yellow = yield. School bus amber = you MUST prepare to stop; school bus red + stop arm = stop at least 10 feet away. All tested on the PennDOT knowledge exam.

7. Pennsylvania Pavement Markings: Lane Lines, 100-Foot Railroad No-Pass Zone and Work Zone Headlight Requirements

Yellow lines separate opposing traffic. White lines separate same-direction traffic. The PennDOT test covers lane lines, road arrows, curb markings, and pavement symbols. including the 100-foot no-passing zone near railroad grade crossings and the no-parking zone within 50 feet of the nearest rail.

Line Colors

Yellow lines

Separate traffic moving in opposite directions

White lines

Yellow curb

No parking or stopping at any time

Red curb

No stopping, standing, or parking. fire zone

White curb

Key test point: Yellow lines always separate opposing traffic. White lines always separate same-direction traffic. This is a foundational rule that appears on nearly every DMV exam.

8. Pennsylvania Work Zone Laws: Headlights Required, Yield to Workers and a 60-Day Suspension for Flagperson Violations

Pennsylvania law requires drivers to turn on headlights when driving through a work zone, a specific requirement to increase vehicle visibility and heighten driver awareness. Yield the right-of-way to workers and construction vehicles in the active work zone. Workers, barricades, and heavy machinery may be very close to traffic. Many crashes occur in the transition zone before the work area begins.

Road Work Ahead

Construction zone begins ahead. reduce speed and be alert

Flagger Ahead

A person is directing traffic. obey their signals immediately

Workers Ahead

Road workers are present. slow down and be prepared to stop

Active Work Zone

You are in an active work zone. fines doubled, drive with extra caution

End of Active Work Zone

Work Zone Headlights

Headlights required in this work zone

Lane Closed Ahead

A travel lane ends ahead. merge early and do not pass in the closed lane

Road Closed

Road is completely closed. do not enter, follow detour signs

Orange barrels / cones

Mark lane boundaries and closures in active work zones

Channelizing devices (barricades)

Direct traffic around obstacles or closed areas

• You must obey flagpersons and police officers directing traffic in Pennsylvania work zones.
• Pennsylvania law requires you to turn on your headlights when driving through a work zone. this is a specific legal requirement, not a suggestion.
• Many crashes occur in the transition zone before the work area. slow down as soon as you see the first warning signs, before you reach the active zone.
• Do not follow vehicles too closely in work zones. if traffic suddenly slows or stops, you may have no room to maneuver. Stay in your lane; oncoming traffic may have no room to move either.

Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.

9. Pennsylvania Railroad Crossings: No Passing Within 100 Feet, No Parking Within 50 Feet and Following Required Vehicles

Pennsylvania prohibits passing within 100 feet of or when crossing any intersection or railroad grade crossing. No parking within 50 feet of the nearest rail. Required vehicles. school buses, taxis, public/private buses, and hazmat trucks. must stop at railroad crossings. When following these vehicles, anticipate the stop and maintain adequate following distance.

Advance Warning Sign

Railroad crossing ahead. the first sign you see. Begin slowing down.

RR Crossbuck Sign (X-shaped)

Located at the crossing itself. yield to trains. Treat as a yield sign if no gates or lights.

Railroad Crossing (at crossing)

Marks the exact railroad crossing location

Crossing Gates

Lower when a train is coming. never drive around or under a lowered gate

Pavement markings (X + RR)

Painted on the road surface before the crossing as an advance warning

Flashing Red Lights

A train is approaching, stop and wait. Do not proceed until lights stop and it is fully clear.

Stop Line

Stop before the tracks; PA prohibits passing within 100 feet of a railroad grade crossing; no parking within 50 feet of the nearest rail

• The round yellow advance warning sign is the first sign before a PA railroad crossing. slow down and look both ways.
• Passing within 100 feet of a railroad grade crossing on a two-lane road is prohibited. this is a no-passing zone.
• No parking within 50 feet of the nearest rail of a railroad crossing.
• School buses, taxis, public/private buses, and trucks transporting hazardous materials must stop at railroad crossings. be prepared to stop when following these vehicles.
• Never stop on or attempt to cross the tracks if there is not enough room for your vehicle on the far side.

Key test point: Passing within 100 feet of a railroad grade crossing is prohibited in Pennsylvania. Required vehicles must stop. No parking within 50 feet. All rules are tested on the PennDOT exam.

10. Pennsylvania School Zone (15 mph) and Bus Laws: 10-Foot Stop, 60-Day Suspension and What Counts as a Divided Highway

Pentagon-shaped school zone signs in Pennsylvania precede a 15 mph speed limit when lights are flashing or during the indicated time period. When a school bus stops with red lights flashing and stop arm extended, stop at least 10 feet away. from behind, coming toward it, or at an intersection. Violation = 60-day suspension and 5 points. The divided highway exception only applies with a physical barrier. guiderails, concrete, curbs, grass strips, a stream, or trees. A painted center line does not count.

School Zone

School ahead. be alert for children, reduce speed

School Speed Limit

Pennsylvania school zone speed is 15 mph when lights flash or during indicated hours; violation = 60-day suspension + 5 points; stop at least 10 feet from bus

Speed Limit Lights Flashing

Speed limit applies only when the flashing lights are active

School Crossing Ahead

Crosswalk used by schoolchildren ahead. yield to crossing guard and students

• Pennsylvania school zone speed is 15 mph when the lights on the school zone sign are flashing or during the time period indicated on signs.
• When a school buss amber (yellow) lights flash, you MUST prepare to stop, this is a legal requirement in Pennsylvania.
• When the red lights flash and the stop arm extends, stop at least 10 feet from the bus. Stop if you are behind the bus, coming toward it, or approaching an intersection where the bus is stopped.
• Remain stopped until the red lights stop flashing, the stop arm withdraws, and the children have reached a safe place.
• Exception: You do not have to stop if on a separate roadway or opposite side of a divided highway with a physical barrier, guiderails, concrete barriers, curbs, grass strips, a stream, or trees qualify. A painted center line does NOT qualify.
• Violation: 60-day license suspension and 5 points.

Key test point: The pentagon shape is used exclusively for school signs. No other sign category uses this shape. making it one of the easiest shapes to identify on the exam.

11. Pennsylvania Pedestrian and Bike Signs: Never Force a Cyclist Off the Road: It is Illegal and Can Mean Criminal Charges

Pedestrians have right-of-way in all Pennsylvania crosswalks. PA law specifically states it is illegal to force a bicyclist off the road. and drivers may face criminal charges for doing so. Give cyclists as much clearance as possible when approaching or passing. Both sign types use fluorescent yellow-green and are tested on the PennDOT knowledge exam.

Pedestrian Crossing Sign

A marked crosswalk is ahead. watch for pedestrians crossing

Bicycle Crossing Sign

Cyclists frequently cross here. reduce speed and yield to bikes

No Bicycles

Bicycles are prohibited on this road or path

No Pedestrian Crossing

Pedestrians must not cross here

• Pedestrians always have the right-of-way in Pennsylvania crosswalks. marked or unmarked.
• When approaching or passing a bicycle, slow down and allow as much clearance as possible.
• It is illegal to force a bicyclist off the road in Pennsylvania. you may face criminal charges. Never turn sharply in front of a bicycle.
• Do not sound your horn close to a cyclist. it may startle them into your path. If you must use it, tap quickly and lightly.
• Watch carefully for cyclists when making turns. Children on bikes may come onto the road from sidewalks without warning.
• Fluorescent yellow-green is used for both school and pedestrian/bike signs. the shape distinguishes between them.

Key test point: Pedestrians always have right-of-way at crosswalks. marked or unmarked. This rule appears on virtually every state DMV exam.

12. How to Pass Pennsylvania PennDOT 18-Question Test: 15 Correct, Headlights in Work Zones and the Physical Barrier Bus Rule

• 18 questions, 15 correct required. Fail. retake the next business day. Practice questions and "possible driving situations" are available on PennDOTs website. Visit penndot.gov before your test.
• Pennsylvania school zone = 15 mph. Not 20, not 25. 15. Applies when zone sign lights are flashing or during the indicated time period. Speeding here carries 3 points.
• School bus amber lights = you MUST prepare to stop. This is a legal requirement in Pennsylvania. not just a courtesy. Stop at least 10 feet from the bus when red lights flash. Violation = 60-day suspension + 5 points.
• Divided highway exception requires a physical barrier. Guiderails, concrete barriers, grass strips, a stream, or trees qualify. A painted line does NOT. Know what counts and what does not. it is tested.
• Turn on headlights in work zones. it is the law. Pennsylvania is one of the few states with this specific requirement. It is designed to increase your vehicles visibility and your own awareness.
• Speed limits. School zones: 15 mph. Other highways: 55 mph. Interstates/freeways: 65 mph where posted.
• Railroad crossings: 100-foot no-passing zone. You may not pass within 100 feet of a railroad grade crossing on a two-way road. No parking within 50 feet of the nearest rail.
• Forcing a cyclist off the road = criminal charges. Pennsylvania specifically states this. give cyclists as much clearance as possible, never turn sharply in front of them, and cooperate with their hand signals.
• Flashing signals. Flashing red = full stop. Flashing yellow = slow and yield.
• Horse-drawn vehicles follow the same road signs as motor vehicles. Pennsylvania specifically includes horse-drawn vehicles in its vehicle sign laws. an unusual tested detail for rural PA routes.
