## WARNING SIGNS: 

COLOR: Yellow, with black letters or symbols 

MEANING: You are approaching a haz- ardous location or a location where there 

is a special rule, as shown in the sample signs. Sometimes a warning sign is joined with a yellow and black “recommended speed” sign. This indi- cates reduced speed is advised in that area. 

## Work Area Signs 

COLOR: Orange, with black letters or symbols 

MEANING: People are at work on or near the roadway and traffic can be controlled by a flag person. A work area speed limit as low as 25 MPH (40 km/h) can be posted. Even if no speed limit is provided, you must drive at a reduced speed through the work zone and you must always obey the flag persons. These illustrations show some signals a flag person will use. Know and obey them.

## DESTINATION SIGNS: 

COLOR: Green, with white letters 

MEANING: Show the direction and distance to locations. 

## Route Signs 

COLOR: Varied. 

MEANING: Indicate interstate, U.S., state or county routes. The shape tells you the type of route you are on. The sample signs, left to right, are for state, U.S., and interstate routes. When you plan a trip, use a highway map to decide which routes to take. During the trip, watch for destina- tion signs so you will not get lost, or have to turn or stop suddenly. 

## SERVICE SIGNS: 

COLOR: Blue, with white letters or symbols 

MEANING: Show the location of services, like rest areas, gas stations, camping or medical facilities. 

## TRAFFIC SIGNALS 

## Traffic Lights 

Traffic lights are normally red, yellow and green from the top to bottom or left to right. At some intersections, there are lone red, yellow or green lights. Some traffic lights are steady, others flash. 

Some are round, and some are arrows. State law requires that if the traffic lights or controls are out of service or do not operate correctly when you approach an intersection, you must come to a stop as you would for a stop sign. You must then continue according to the rules of right-of-way, unless you are told to continue by a traffic officer.
