Maryland Road Signs: MVA 25-Question Test & Speed Camera Work Zones
What do flashing blue lights mean in a Maryland work zone? How long is the Maryland MVA knowledge test and how many questions? Does Maryland require buses to stop at all railroad crossings? The MDOT MVA at mva.maryland.gov gives 25 questions in 20 minutes. Flashing blue lights in work zones indicate an active speed camera. All buses must stop at railroad crossings. Cyclists get 3 feet of mandatory clearance.

1. Why Maryland MVA Tests Signs on a 20-Minute, 25-Question Clock
Maryland roads connect Baltimore dense I-695 Beltway, Annapolis,ay Bridge approach on US-50, the I-270 tech corridor through Rockville and Gaithersburg, Frederick Civil War-era routes, and the Eastern Shores flat two-lane causeways. The Maryland Department of Transportation Motor Vehicle Administration (MDOT MVA) knowledge test is 25 questions, 20 minutes, taken at an MVA location. A free online tutorial with practice questions is available at mva.maryland.gov/drivers. The manual contains all tested information.
2. Maryland Sign Recognition: Shape, Color, Symbol: All Tested on the MVA 25-Question Exam
On Maryland I-95 express lanes, the Bay Bridge approach on US-50, and the winding Appalachian mountain routes, shape and color tell you a signs category before you can read the text.

6. Maryland Traffic Signals: Work Zone Speed Cameras, Flashing Blue Lights & MVA Exam Coverage
Flashing red = stop sign. Flashing yellow = yield. The Maryland MVA knowledge test covers all signal types: standard lights, arrow signals, flashing signals, and pedestrian signals. In Maryland work zones, flashing blue lights mean speed cameras are active. flashing amber/yellow lights mean workers are present.
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
Treat as a YIELD sign, slow down, look carefully, and proceed with caution.
Flashing Red Beacon
Overhead flashing red beacon. treat as a stop sign. Come to a full stop, then proceed when safe.
Flashing Green Arrow
You may turn in the direction of the arrow after yielding to oncoming traffic and pedestrians.
Pedestrian Signals
WALK / White Walking Figure & DONT WALK / Orange Hand
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. In Maryland work zones, flashing blue lights = active speed cameras; flashing amber = workers present. All are tested on the Maryland MVA knowledge exam.
7. Maryland Pavement Markings: Lane Lines, Work Zone Temporary Markings & the 3-Foot Bicycle Passing Law
Yellow lines separate opposing traffic. White lines separate same-direction traffic. The Maryland MVA knowledge test covers lane lines, road arrows, curb markings, work zone temporary pavement markings, and the mandatory 3-foot bicycle passing clearance.
Line Colors
Yellow lines
Separate traffic moving in opposite directions
White lines
Separate traffic moving in the same direction, or mark the edge of the road
Line Types
Broken yellow line (Single)
Passing allowed when safe on your side

Lane restricted to vehicles with 2 or more occupants during posted hours
Yellow curb
No parking or stopping at any time
Red curb
No stopping, standing, or parking. fire zone
White curb
Passenger loading/unloading only. brief stops permitted
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. Maryland Work Zone Laws: Speeding Fines Much Higher, Speed Cameras Active & Flashing Blue Lights Mean Watch Out
Orange signs mark active work zones throughout Maryland road network. Maryland law states speeding fines are much higher in work zones, and even higher when workers are present. Flashing blue lights in work zones mean speed cameras are active. Flashing amber/yellow lights mean there are workers present. Stay alert, obey posted limits, and do not tailgate.
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

Orange barrels / cones
Mark lane boundaries and closures in active work zones
Channelizing devices (barricades)
Direct traffic around obstacles or closed areas
- Obey the flaggers directions. their authority overrides all existing signs and signals.
- Speeding fines are much higher in work zones and even higher when workers are present. this is explicitly stated in the Maryland Drivers Manual.
- Flashing blue lights in a work zone mean speed cameras are active. Flashing amber/yellow lights mean workers are present. pay close attention and slow down.
- Work zone conditions change constantly. be ready to react, including coming to a complete stop if traffic in front of you stops.
- Minimize distractions in work zones. no cell phones, no changing radio stations, no eating.
Key test point: Orange always means construction or work zone. If you see orange, reduce speed and increase following distance immediately.
9. Maryland Railroad Crossings: Buses and School Buses Must Stop and Never Start Until Tracks Are Clear
At every Maryland railroad crossing, buses, school buses, and trucks carrying hazardous materials must stop before crossing. Never start to cross the tracks unless you can get completely over before a train comes. make sure there is room on the other side before proceeding. After a train passes, look both ways; another train may be coming on another track.
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 here before the tracks. never start crossing unless you can fully clear the tracks; buses and school buses must stop before every Maryland railroad crossing
- The round yellow advance warning sign is always the first sign you see approaching a crossing.
- Never start to cross the tracks unless you can get completely over before a train comes. ensure there is room on the other side.
- After a train passes, look both ways before starting over the tracks. another train may be coming on another track.
- Buses, school buses, and trucks carrying hazardous materials must stop before every Maryland railroad crossing.
- Be aware of other vehicles stopping before the crossing. anticipate those stops and allow extra following distance.
Key test point: Never start over tracks until completely sure you can clear them. After one train, check both ways for a second. Buses must always stop. both rules appear on the Maryland MVA exam.
10. Maryland School Zone and School Bus Laws: Stop 20 Feet Back and Know the Physical Barrier Exception
Pentagon-shaped, fluorescent yellow-green signs mark school zones. Maryland requires obeying posted school zone speed limits. When a school bus has stopped with flashing red lights, you must stop at least 20 feet from the front or rear of the bus. You may not start moving until the bus starts moving or turns off its flashing red lights.
School Zone
School ahead. be alert for children, reduce speed
School Speed Limit
Obey the posted school zone speed limit. Maryland requires stopping at least 20 feet from a school bus with flashing red lights, whether you are in front of or behind it
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
- Obey posted school zone speed limits. and obey speed limits in residential areas where young bicyclists may be present.
- When a school bus stops on the road with flashing red lights, you must stop at least 20 feet from the back of the bus if you are behind it, or 20 feet from the front if you are in front of it.
- You may not start moving again until the school bus starts moving or turns off its flashing red lights.
- Exception: If you are on a multiple-lane road divided by a physical barrier, do not stop if the bus is on the other side of the barrier.
- Children on bicycles are unpredictable near school zones. expect sudden direction changes and small riders who may be hard to see.
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. Pedestrian & Bike Signs in Maryland: Mandatory 3-Foot Passing Law and Young Cyclists in School Zones
Pedestrians have right-of-way at all crosswalks. marked or unmarked. Maryland law requires leaving at least 3 feet between your vehicle and a bicycle when passing. this applies in a bike lane, on the shoulder, or in the same lane as your car. Make sure you can see the bicycle in your rear-view mirror before returning to your lane.
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 marked crosswalks. yield and stop as necessary.
- Maryland requires at least 3 feet of passing clearance between your vehicle and a bicycle. whether the cyclist is in a bike lane, on the shoulder, or in your lane. Confirm the bicycle is in your mirror before returning to the lane.
- Be prepared to slow down and wait for oncoming traffic to clear before passing a cyclist.
- Children on bicycles are unpredictable and may enter the road from driveways or near parked cars. obey speed limits in school zones and residential areas.
- 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 Maryland MVA Knowledge Test in 20 Minutes Flat
- 25 questions, 20 minutes at an MVA location. The Maryland MVA knowledge test is taken in person. Use the free online tutorial at mva.maryland.gov/drivers, it has practice questions that mirror the actual test.
- The manual has everything you will be tested on. Study all sections. the MVA states that the manual contains all the information tested. Do not rely only on sign shapes.
- Work zone: fines much higher, cameras active. Speeding fines in Maryland work zones are much higher and even higher when workers are present. Flashing blue lights = speed cameras active. Flashing amber = workers present.
- School bus: stop 20 feet from front or rear. Whether you are behind or in front of a stopped school bus with flashing red lights, you must stop at least 20 feet away. Physical barrier on a multi-lane road = no stop required on the other side.
- Railroad: clear the tracks before crossing. Never start across unless you can completely clear the tracks. After one train passes, check for a second before moving. Buses and school buses must stop before every crossing.
- 3 feet for cyclists. mandatory in Maryland. Leave 3 feet when passing a bike in any lane, shoulder, or bike lane. Confirm the bicycle is visible in your mirror before returning to your lane.
- Flashing signals. Flashing red = full stop, then proceed when safe. Flashing yellow = slow and yield. Also know: flashing blue = speed camera; flashing amber = workers present.
- Aggressive driving carries enhanced penalties. Speeding, tailgating, unsafe lane changes, and ignoring signals are examples of aggressive driving in Maryland. judges can double fines in some circumstances.
- Yellow vs white lines. Yellow = opposing traffic. White = same-direction traffic. Always tested.
