A road sign in the shape of an octagon will always be a stop sign. Come to a full stop at an intersection controlled by this sign. Stop at the marked stop line or before entering the crosswalk or before your vehicle enters the intersection. Let other vehicles or pedestrians pass if they are in your path.

This sign shape is used for yield signs. Yield the right of way. Slow down and let vehicles crossing your path go by. If necessary, stop before going ahead. If pedestrians are in or about to enter the crosswalk, stop until they have crossed the roadway, then proceed.

This sign will be on the left-hand side of the road or highway. It warns you of a no-passing zone.

Diamond shaped signs are used as warning signs. These signs alert you to special road hazards. Words or pictures on the sign will show you why you need to slow down or use extra caution.

These will be regulatory or guide signs. Vertical signs indicate what you should or should not do, such as speed limit signs. Horizontal signs give directions or information about services drivers may want.

A road sign in the shape of a pentagon will refer to a school crossing or school zone. The color of the sign may be yellow or florescent yellow/green.

All railroad crossing signs are this shape and are placed at each crossing. Sometimes there is a number under the crossbuck which will show you how many sets of tracks there are.
