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. The MVA knowledge test tests signs. master this table and use the free tutorial at mva.maryland.gov/drivers before your visit.

Shape	Diagram	Meaning	Example Sign

Diamond		Hazard ahead; slow down, stay alert, and be ready to stop or steer
Rectangle (vertical)		Legal requirement; obey this sign or face fines and points on your record
Rectangle (horizontal)		Informational sign; read it and use it to navigate or plan your route
Pentagon (5-sided)		School zone ahead; reduce speed and watch for children crossing
Round (circle)		Railroad crossing ahead; slow down, look both ways, and prepare to stop
Pennant		No passing zone; do not attempt to overtake any vehicle ahead

3. Maryland Regulatory Signs: MVA Point System Violations and the 20-Foot School Bus Stop Rule

Regulatory signs carry legal force in Maryland. violations are moving offenses recorded on your MVA driving record. Failing to stop for a school bus is one of the most serious violations. White rectangular signs, prohibitory signs, and lane-control signs are all tested on the Maryland MVA knowledge exam.

4. Maryland Warning Signs: Bay Bridge Wind Alerts, I-95 Merge Hazards & Appalachian Curve Warnings

Diamond-shaped warning signs flag hazards ahead. on Maryland roads that means wind advisory warnings on the Bay Bridge, sharp curve warnings on Western Maryland mountain routes, pedestrian crossing alerts near Baltimore dense urban areas, and railroad grade crossings on rural branch lines. Orange signs mark work zones where speeding fines are much higher and speed cameras with flashing blue lights may be active.

5. Maryland Guide & Informational Signs: Navigating I-95, I-495 Capital Beltway, US-50 & the Bay Bridge

Guide signs do not regulate driving. they show destinations, distances, and services. Green = highway navigation. Blue = motorist services. Brown = parks and recreation.

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

Flashing Signals

Pedestrian Signals

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

Line Types

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.

• 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.

• 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.

• 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.

• 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.
