What does an eight-sided (octagon) sign always mean?: Come to a full stop; The octagon is used only for STOP signs. Stop at the stop line, or before the crosswalk, or before the intersection if neither is marked, then yield to people and traffic. (Rules of the Road, p. 63, 65.)
What does a three-sided sign pointing down mean?: Yield the right of way; The downward triangle is the YIELD sign. Slow to a safe speed, give the right of way to vehicles and pedestrians, and stop if needed at the crosswalk or before the intersection. (Rules of the Road, p. 63, 65.)
A round yellow sign warns you of what ahead?: A railroad crossing; A round yellow advance warning sign, usually with an X and two R letters, tells you a railroad crossing is ahead, often up to 750 feet away. Slow down, look and listen. (Rules of the Road, p. 63, 81.)
What does a diamond-shaped sign tell you?: A possible hazard is ahead; Diamonds are warning signs. They alert you to road conditions and dangers ahead, such as curves, hills, merging lanes, crossings or work zones, so you can slow down early. (Rules of the Road, p. 63, 68.)
A five-sided sign shows two children walking, with no arrow. What does it mean?: A school is nearby; The five-sided (pentagon) sign is yellow or yellow-green. Two children walking means a school is nearby. Slow down and watch for children. (Rules of the Road, p. 64.)
A five-sided school sign has a small arrow pointing down. What does it mean?: You are at a school crossing; With a downward arrow, the school sign marks the crosswalk itself. Without the arrow, it means a school is nearby. Slow down and stop for children in the crosswalk. (Rules of the Road, p. 64.)
What does a pennant-shaped (sideways triangle) yellow sign mean?: No passing zone begins; The pennant is the NO PASSING ZONE sign. It stands on the left side of a two-lane, two-way road where the no passing zone begins, along with no passing lines on the pavement. (Rules of the Road, p. 64, 71.)
On which side of the road is the pennant NO PASSING ZONE sign posted?: The left side; The pennant stands on the left side of a two-lane, two-way road at the start of the no passing zone, so a driver about to pull out to pass sees it. (Rules of the Road, p. 64, 71.)
Square and rectangular signs are used for which two kinds of signs?: Regulatory or guide signs; Squares and rectangles can be regulatory signs you must obey, such as SPEED LIMIT, or guide signs that tell you where you are and where to go. (Rules of the Road, p. 64.)
What does red mean on a road sign?: A rule you must obey; Red signs are regulatory signs and must be obeyed. They include STOP, YIELD, DO NOT ENTER and WRONG WAY. (Rules of the Road, p. 64.)
What do black and white signs like SPEED LIMIT usually tell you?: A rule you must obey; Many black and white signs are regulatory and must be obeyed, such as SPEED LIMIT, ONE WAY and KEEP RIGHT. Others are route markers that guide you. (Rules of the Road, p. 64, 65.)
What does a yellow sign mean?: A warning of dangers ahead; Yellow is used for warning signs. They tell you about road conditions and dangers ahead, such as curves, hills, crossings and lane changes, so you can slow down in time. (Rules of the Road, p. 64.)

Fluorescent yellow-green signs warn you about what?

People, bikes, schools or play areas

Yellow-green warning signs alert you to pedestrian and bicycle crossings, playground areas, school bus stops and school zones. The bright color helps you notice them sooner. (Rules of the Road, p. 64, 68.)
What does an orange sign mean?

Work zone ahead

Orange signs warn of construction or maintenance ahead. Workers may be close to your lane, so slow down, follow the posted work zone speed and be ready to stop. (Rules of the Road, p. 64, 72.)
When you see an orange sign, what should you do?

Slow down and be ready to stop

An orange sign means be alert, adjust your speed and be prepared to stop. Workers may be close to traffic, and the lanes may shift or close. (Rules of the Road, p. 64.)
What do green signs tell you?

Where you are and where to go

Green is used for guide signs. They tell you where you are, which way to go and the distance to places ahead. (Rules of the Road, p. 64, 74.)
What do blue signs tell you about?

Services along the road

Blue is used for guide signs about services along the roadway, such as gas, food, lodging and hospitals. (Rules of the Road, p. 65.)
What does a brown sign point you to?

Parks and recreation areas

Brown is used for signs about parks and recreation, such as state parks, campgrounds and historic sites. (Rules of the Road, p. 65.)
What can a pink (coral) sign warn you about?

A traffic incident ahead

Pink may be used for traffic incident signs. They warn of dangers from unplanned events, such as traffic crashes and natural disasters. (Rules of the Road, p. 65.)
What are the three main types of road signs?

Regulatory, warning and guide

The manual groups signs as regulatory (rules you must obey), warning (conditions and dangers ahead) and guide (where you are and how to get there). Each type has its own shapes and colors. (Rules of the Road, p. 63.)
A shield-shaped sign with a number on it is what kind of sign?

A route marker

Route markers are guide signs that name the road, such as Interstate 55. Freeway and county route markers have their own shapes, unlike most rectangular guide signs. (Rules of the Road, p. 74.)
How do signs tell you their type before you can read the words?

By their shape and color

Each type of sign is identified by its shape and color, so you can recognize a STOP or warning sign from far away, even before the words are readable. The written test asks you to identify signs this way. (Rules of the Road, p. 63.)
