Georgia DMV Permit Test: Sign Shapes, Colors, and Regulatory Signs Concepts

Importance ★★★★★ · 35% (estimate)

Overview

Half of the Georgia knowledge exam is the Road Signs test, and it is given in English only. This chapter covers the basics: what each sign shape and color means, and how to read the signs that state rules you must obey.

Shape comes first. The eight-sided sign is used only for STOP, and the triangle pointing down is used only for YIELD. Upright rectangles are usually rule signs, such as SPEED LIMIT, while wide rectangles are usually guide signs that show directions and places. Diamonds warn, the five-sided sign marks a school zone or crossing, and the round sign warns of a railroad crossing ahead.

Color tells you the job of the sign. Red is used for STOP, YIELD, DO NOT ENTER, and WRONG WAY. Green signs guide you, blue signs show services such as gas and lodging, brown signs lead to parks and recreation, and orange signs mark construction and maintenance work. A red circle with a slash over a picture means the action shown is not allowed.

Some rule signs come with Georgia turning rules. You may turn right on a steady red light after a complete stop unless a sign forbids it, and you may turn left on red only from a one-way street onto another one-way street going left. Where NO TURN ON RED is posted, wait for green. On multi-lane roads, slower traffic must keep right and leave the passing lane.

Key concepts

  • STOP sign

    A red eight-sided sign. Stop at the stop line. If there is no stop line, stop before the crosswalk. If there is no crosswalk, stop where you can best see oncoming traffic. Then yield and go when it is safe.

    Memory tipEight sides: stop all the way, every time.

  • YIELD sign

    A red and white triangle pointing down. Slow down, stop if needed, and let vehicles in the intersection or close to it go first.

    Memory tipTriangle pointing down: give way.

  • Regulatory signs

    Signs that state rules you must obey just like traffic laws, such as SPEED LIMIT, ONE WAY, DO NOT ENTER, WRONG WAY, and NO TRUCKS. Most are upright white rectangles. A red circle with a slash means the action shown is not allowed.

    Memory tipWhite rectangle: a rule, not a suggestion.

  • Sign colors

    Red: stop, yield, and do not enter. Yellow: general warning. Orange: construction and maintenance. Green: directions and guide signs. Blue: services. Brown: parks and recreation.

    Memory tipOrange means workers; blue means services.

  • Turning on red

    Unless a sign forbids it, you may turn right on a steady red light after a complete stop and yielding to traffic and pedestrians. A left turn on red is allowed only from the left lane of a one-way street onto a one-way street whose traffic moves to your left.

    Memory tipRight on red after a full stop; left on red only one-way to one-way.

  • Slower traffic keep right

    On a road with two or more lanes in your direction, slower drivers must move out of the left (passing) lane when faster traffic comes up behind them, even if they are at the speed limit.

    Memory tipLeft lane is for passing, not cruising.

See it in a picture

Seven labeled sign shapes: a red octagon reading STOP, a red and white downward triangle reading YIELD, an upright white rectangle reading SPEED LIMIT 55, a wide green rectangle with a white arrow, a yellow diamond, a yellow-green five-sided sign, and a round yellow sign with an X and two R letters.
Each sign shape has its own job, so you can tell what a sign means before you can read it.

Often tested

  • The eight-sided sign is used only for STOP.
  • The triangle pointing down is used only for YIELD.
  • Upright rectangles state rules; wide rectangles guide you.
  • A red circle with a slash means the action shown is not allowed.
  • Where NO TURN ON RED is posted, wait for the green light.
  • Blue signs show services; orange signs mark work zones.

Verified practice questions from this unit.

Practice questionReviewedRoad Signs › Sign Shapes, Colors, and Regulatory Signs★★★★★

Question 1. A red sign with eight sides always means what?

  1. ① A stop sign is ahead
  2. ② Do not enter this road
  3. ③ Slow down and give way only if needed
  4. ④ Come to a complete stop
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ④ Come to a complete stop

Key point: Eight sides (octagon) is used only for STOP

The eight-sided shape (an octagon) is used only for the STOP sign. You must come to a complete stop, then go only when the way is clear.

Wrong choices

  • A stop sign is ahead: A stop sign ahead is warned by a yellow diamond sign, not a red octagon.
  • Do not enter this road: DO NOT ENTER is a square sign with a red circle and a white bar.
  • Slow down and give way only if needed: Slowing and stopping only if needed is what a YIELD sign (a triangle pointing down) asks.

Question 2. What does a sign shaped like a triangle pointing down tell you to do?

  1. ① Watch for a railroad crossing
  2. ② Merge without slowing down
  3. ③ Slow down, stop if needed, and let other traffic go first
  4. ④ Stop every time, even if no one is coming
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ③ Slow down, stop if needed, and let other traffic go first

Key point: Triangle pointing down = YIELD

A triangle pointing down is the YIELD sign. Slow down to a safe speed, stop if you must, and let vehicles and people already in the intersection or close to it go first.

Wrong choices

  • Watch for a railroad crossing: A railroad crossing ahead is shown by a round yellow sign.
  • Merge without slowing down: You must be ready to slow or stop. You may not force your way in.
  • Stop every time, even if no one is coming: A full stop every time is what a STOP sign requires. At a YIELD sign you stop only when needed.

Question 3. What does this sign mean?

A square white sign. Inside is a large red circle with a wide white horizontal bar across its middle. White words are printed in the red circle above and below the bar.
  1. ① The road ahead is closed for construction
  2. ② You must not enter this road from your direction
  3. ③ Stop first, then enter when it is clear
  4. ④ A one-way street begins, so go ahead slowly
▼ Show answer and explanation▲ Hide answer and explanation

Answer: ② You must not enter this road from your direction

Key point: DO NOT ENTER: you may not drive in from this side

This is the DO NOT ENTER sign. Traffic on the road beyond it comes toward you, so you must not enter from your direction. You often see it at the wrong end of one-way streets and exit ramps.

Wrong choices

  • The road ahead is closed for construction: Road closures are shown with orange or white ROAD CLOSED signs, not this sign.
  • Stop first, then enter when it is clear: Stopping first does not make it legal to enter. You may not enter at all.
  • A one-way street begins, so go ahead slowly: You must not go ahead at all, slowly or not. Entering would put you against traffic.
