Beyond the rules, signs warn you of hazards, protect road workers, and guide you to your destination and to services. Learn each family by its color so you know what to expect before you're close enough to read it.

Warning signs (narrow bridge, curves, pedestrian crossing)
Warning signs: narrow bridge, divided highway, winding road, school crossing

Know the rule

Warning signs are yellow with black letters or symbols. They mean you're approaching a hazardous location or a place with a special rule.

Know the rule

A warning sign may be paired with a yellow and black "recommended speed" sign, which means a reduced speed is advised in that area.

US and Interstate route markers
Route signs: U.S. route, interstate and New York State route

Know the rule

Route signs vary in color and mark interstate, U.S., state or county routes; the shape tells you the type of route. Plan trips with a highway map and watch destination signs so you don't get lost or turn or stop suddenly.

Service signs (gas, camping)
Service signs: gas station and camping

Know the rule

Service signs are blue with white letters or symbols. They show the location of services such as rest areas, gas stations, camping or medical facilities.

Put it into practice

You pass an orange ROAD WORK sign, but no speed limit is posted. You still must slow down through the work zone. When a flagger holds up a STOP paddle, you stop, even if the road ahead looks clear.
