Minnesota Road Signs Practice key terms

A sign that gives a legal order or prohibition, such as a speed limit, stop, or no-turn rule. Drivers must obey it; violating one is a traffic offense rather than a suggestion.

A white rectangle with black numerals showing the maximum lawful speed in miles per hour under normal conditions. It sets the legal limit, not a target, and lower speeds are required when conditions are poor.

The rule that a driver must never travel faster than is safe for current conditions, regardless of the posted maximum. Rain, ice, fog, traffic, or darkness can make the posted limit too fast.

A regulatory sign that directs a required action rather than a prohibition, such as keeping right of a median or turning only in the direction shown by an arrow.

An eight-sided red sign with white letters requiring a complete halt at the stop line or crosswalk. The driver yields to cross traffic and pedestrians, then proceeds only when clear.

An inverted triangle, red-bordered and white inside, requiring a driver to slow or stop and give the right of way to traffic on the intersecting road. Stopping is required only when necessary to yield.

A black-and-white horizontal arrow sign showing that traffic on that street moves only in the arrow's direction. Entering against the arrow is illegal and dangerous.

A yellow diamond sign alerting drivers to a change or hazard ahead, such as a curve, intersection, or narrowing road. It does not create a legal limit but tells drivers to slow and prepare.

A yellow rectangular sign mounted below a warning sign showing a recommended safe speed for the hazard, often a curve or ramp. It is advice, not the legal maximum, but exceeding it is unsafe.

A yellow rectangular sign bearing a black arrow-shaped chevron, placed on the outside of a sharp curve to show its direction. A series of chevrons guides drivers through the turn.

The standard shape for warning signs in the United States, used because it is recognizable from the back and at a distance. Yellow diamonds warn of conditions ahead.

A sign giving directions, distances, destinations, or route information, typically green, blue, or brown. Guide signs help navigation and are informational rather than regulatory.

A red, white, and blue shield-shaped sign identifying an Interstate highway. Even-numbered routes generally run east-west and odd-numbered routes generally run north-south.

A small green sign along a highway showing the distance in miles from a reference point, often a state line. It helps drivers report their location in an emergency.

A green guide sign showing the exit number and destination for an upcoming off-ramp. Drivers should read it early and move to the correct lane well before the exit.

A blue sign listing nearby amenities such as gas, food, lodging, or a hospital. Blue indicates services, while brown indicates recreation and cultural points of interest.

A brown guide sign pointing to parks, historic sites, or recreational areas. The brown background distinguishes these destinations from general highway direction signs.

An orange diamond or rectangular sign warning of construction, maintenance, or workers ahead. Orange signals that normal rules and lanes may change and that fines often increase.

A worker using a sign or paddle to stop and release traffic through a work zone. Drivers must obey the flagger's signals, which override normal signals and signs.

The cones, barrels, barricades, and signs used to channel traffic safely through or around a work zone. Drivers must follow these devices even when they conflict with permanent markings.

A yellow-green pentagon or diamond sign marking an area near a school where children cross. Speed limits are often reduced during posted hours or when lights flash.

A yellow-green pentagon-shaped sign showing two figures walking, used at school crossings. Its unique five-sided shape makes it recognizable even when partly obscured.

A marked path across a roadway for pedestrians, shown by painted lines or a distinct surface. Drivers must yield to pedestrians in a crosswalk, marked or unmarked.

A yellow diamond sign with a walking-person symbol warning that pedestrians may cross ahead. Drivers should slow and scan both sides of the road for people entering the roadway.

A yellow diamond sign with a bicycle symbol warning that cyclists may cross or share the road ahead. Drivers should slow and give cyclists room, especially where a path meets the road.

A yellow diamond sign telling drivers that bicyclists use the roadway and have a right to the lane. Drivers should pass only when safe and leave adequate clearance.

A yellow circular sign with a black X and two R's marking a railroad crossing ahead. Drivers should slow, look both ways, and be ready to stop for an approaching train.

A white X-shaped sign with black letters reading RAILROAD CROSSING, posted at the tracks themselves. It means yield to trains; a smaller sign below may show the number of tracks.

Flashing red lights, bells, and gates at a railroad crossing that warn of an approaching train. Drivers must stop when lights flash or gates lower and never drive around a lowered gate.

A device using colored lights to control traffic at intersections, including steady red, yellow, and green and flashing variants. Each color carries a specific legal duty for drivers.

A signal warning that the light is about to turn red. Drivers should stop if they can do so safely; the yellow light does not mean accelerate to beat the red.

A signal that functions like a stop sign, requiring a full stop before proceeding when clear. Flashing red often appears at intersections where signals are off or at night.

A signal warning drivers to slow down and proceed with caution. It does not require a stop but indicates a hazard such as an intersection or a malfunctioning signal.

A signal permitting movement only in the direction the arrow points, typically a protected turn. Traffic turning on the arrow has the right of way over opposing traffic.

A solid white line painted across a lane where vehicles must stop for a sign, signal, or crosswalk. Stopping beyond it can block pedestrians or intrude into the intersection.

A solid white or yellow line marking the outer edge of the traveled way. A yellow edge line on the left indicates the left side of a divided highway.

Using a sign's outline, such as octagon, triangle, diamond, or pentagon, to identify its meaning quickly. Shape and color let drivers react before reading the words.

The five-sided outline reserved for school crossing signs. Its unique shape helps drivers identify a school area even from the back or when the sign face is dirty.

The legal priority to proceed first at an intersection or crossing. It is given by signs, signals, or rules and is never taken aggressively from another road user.
