Georgia Driver's Handbook, Section 7: Signs, Signals, and Markings

The seven sign shapes, regulatory, warning, guide and work zone signs, traffic and pedestrian signals, pavement markings and roundabouts.

Key rules

1. Shapes: octagon stop, triangle yield, circle railroad ahead, pentagon school, diamond warning, rectangles regulatory or guide. p. 28
2. Flashing red is a stop sign, flashing yellow means caution; a flashing yellow arrow allows a left turn after yielding. p. 34
3. Stop at the white stop line; broken yellow center lines allow passing, solid ones on your side do not. p. 36
4. Roundabouts: yield to circulating traffic, go counterclockwise and always exit to the right. p. 37
