Massachusetts Road Signs Practice key terms

A white rectangular regulatory sign with black numerals showing the maximum legal speed in miles per hour under normal conditions. In Massachusetts, statutory limits apply when no sign is posted, such as 30 mph in thickly settled areas.

A speed cap set by state law that applies without a posted sign, such as 30 mph in thickly settled or business districts, 40 mph on rural highways, and 50 mph on divided highways, unless signs say otherwise.

The numeric limit shown on an installed speed limit sign. A posted value overrides the default statutory limit for that stretch of road and marks the maximum safe speed under favorable conditions, not a target.

An eight-sided red sign with white letters reading STOP. You must come to a complete halt at the stop line, crosswalk, or edge of the intersecting roadway, yield to traffic and pedestrians, then proceed only when clear.

An inverted triangle with a red border and white center. Slow down and give the right-of-way to vehicles and pedestrians on the intersecting road; stop only if necessary before entering or crossing.

The legal priority to move through a given space first. Signs, signals, and rules such as yielding to traffic already in an intersection or to pedestrians in a crosswalk determine who holds it.

An intersection where all approaches have stop signs. Vehicles proceed in the order they arrived; if two arrive at the same time, the driver on the left yields to the driver on the right.

A regulatory sign prohibiting a right turn (or left turn from a one-way onto a one-way) while the signal is red. Where it is absent, Massachusetts generally allows a right turn on red after a full stop and yield.

The permitted maneuver of turning right at a red light after stopping completely, yielding to pedestrians and cross traffic. It is allowed in Massachusetts unless a sign forbids it or a red arrow controls the lane.

A sign that assigns, restricts, or ends the use of a lane, such as left-turn-only, straight-ahead-only, or a mandatory movement arrow. You must follow the direction shown for the lane you occupy.

A sign that states a law, rule, or prohibition drivers must obey, such as stop, yield, speed limits, turn restrictions, and parking rules. Most are rectangular with a white background and black or red markings.

A regulatory sign limiting when, how long, or for whom a space may be used, such as resident-only, tow zone, or time-limited parking. Text and arrows on the sign define the exact area and hours the rule covers.

A permit displayed on the dashboard or mirror, or a special plate, that lets a person with a qualifying disability park in designated accessible spaces. Unauthorized use of a placard or space carries fines.

A sign that alerts drivers to an upcoming hazard or change in road conditions, such as a curve, intersection, or pedestrian crossing. Most are diamond-shaped with a yellow background and black symbols.

A small yellow rectangular sign below a warning sign showing a recommended maximum speed for a hazard such as a sharp curve or ramp. It is guidance for safe passage, not an enforceable speed limit.

A yellow diamond warning sign with a black arrow curving left or right, indicating a bend ahead. A variant with a squiggly arrow marks a winding road with a series of curves.

A large rectangular sign with a black chevron on yellow, placed on the outside of a sharp curve to show the direction of travel. Multiple chevrons guide drivers through the bend.

A yellow diamond sign showing a crossroad symbol, indicating an upcoming intersection where traffic may enter from the side. A side-road version shows a single road joining from the left or right.

A yellow diamond sign with a walking figure, warning that pedestrians may cross ahead, often near a marked crosswalk. Slow down and be ready to stop for anyone in the roadway.

A yellow-green diamond sign showing children walking, marking an area near a school. Lower speed limits often apply during school hours or when children are present, and fines may be increased.

A yellow diamond sign warning of surface hazards ahead, such as slippery when wet, uneven pavement, loose gravel, or a bump. Adjust speed and following distance when you see one.

A round yellow sign with a black X and RR letters, warning of tracks ahead. At crossings with signals or gates, stop when lights flash or gates lower; never drive around a lowered gate.

A sign giving directions, destinations, distances, or route information, usually green with white lettering on highways and often blue for services. Guide signs inform rather than command.

A sign identifying a numbered road, such as an interstate shield, a U.S. route shield, or a state route marker. The shape and color tell you which road system the route belongs to.

A red, white, and blue shield-shaped marker for the Interstate highway system. Even-numbered interstates generally run east-west and odd-numbered ones north-south, with mileage-based exit numbers.

A blue sign with white symbols showing nearby amenities such as gas, food, lodging, or a hospital, often with an exit direction. These signs help you plan stops without leaving the highway blindly.

An orange diamond or rectangular sign warning of road work, lane closures, or workers ahead. Orange marks work zones, where speed limits may be reduced and fines for violations are often doubled.

An area where road construction or maintenance is underway, marked by orange signs, cones, and barricades. Expect narrowed lanes, sudden stops, and workers near the travelway; slow down and stay alert.

An orange diamond sign showing a worker holding a flag, warning that a person will direct traffic ahead. Follow the flagger's signals, which override normal right-of-way rules and signals in the work area.

A cone, drum, or barricade used to guide traffic around or away from a work area. Never cross these devices; they mark the boundary between the safe path and the hazard.

The use of a sign's outline to convey meaning quickly: octagon for stop, inverted triangle for yield, diamond for warning, rectangle for regulation or guide, and round for railroad advance warning.

The use of background color to classify signs: red for stop and prohibition, yellow for warning, orange for work zones, green for guide and destination, blue for services, and white for regulation.

Painted lines and symbols on the road surface that guide and regulate traffic, such as lane dividers, edge lines, crosswalks, and turn arrows. They supplement signs and signals and carry legal weight.

A line dividing traffic moving in opposite directions. A solid yellow line means no passing from your side; a broken yellow line allows passing when safe; double solid yellow means neither side may pass.

A line separating lanes of traffic moving in the same direction. Broken white lines may be crossed to change lanes; solid white lines mark edges or areas where lane changes are discouraged or prohibited.

A marked path for pedestrians across a road, shown by parallel white lines or a ladder pattern. Drivers must yield to pedestrians in a crosswalk, marked or unmarked, and stop when they are crossing.

A solid white line across a lane marking where vehicles must halt at a stop sign or signal. Stop before it so pedestrians and cross traffic have clear space, and never block the crosswalk.

A light controlling traffic flow: red means stop, green means proceed when clear, and yellow warns the light is about to turn red. A steady yellow does not mean speed up.

A signal arrow pointing in the direction where you may not turn while it is lit red. It is more restrictive than a round red light and does not allow a turn on red in that direction.

A center lane marked by two yellow lines with broken inner segments, shared by traffic turning left from either direction. It is only for turning, not for passing or extended travel.
