Stop

A stop sign is red with white letters and has eight sides. When you see a stop sign, you must come to a full stop. You must wait until crossing vehicles and pedestrians have cleared the intersection. You must stop at the stop line if one is present even if it is located past the stop sign. If there is no stop line, pull up and stop near the edge of the intersection, look both ways, and then proceed when it is safe.

Yield

A yield sign is triangular. It is red and white with red letters. It means you must slow down and yield the right-of-way to traffic in the intersection you are crossing or roadway you are entering.

Wrong Way

You made a wrong turn and have entered a lane of oncoming traffic. As quickly and safely as possible, pull off the road, turn around and go back.

Do Not Enter

When you see this sign at roadway openings, do not enter this road.

One Way

Traffic on some roadways and ramps is allowed in one direction only.

Lane Control

These signs use an arrow symbol to tell you which direction you can go from each lane. The signs are along the road or hanging over the road.

Speed Limit

Speed limit signs indicate the maximum speed allowed by law, and do not mean that all parts of the road can be safely driven at those speeds under all conditions. The speed limit is the maximum allowable speed in ideal conditions. Adjust your speed for hills, curves, slippery roadways, limited sight distance, pedestrians, bicyclists, and slow-moving vehicles. These conditions may make the posted speed limit unsafe. By law, when conditions demand it, you must slow down. Interstate highways also have minimum speed limits. If this minimum speed is too fast for you, then you should use another route. You may not drive slower than 40 mph on interstate highways under normal roadway conditions.

Keep Right

Some roadway locations require traffic to pass only to the right side of a feature or obstruction.

Railroad Crossing

The round advance warning sign tells you that you are nearing a railroad crossing.

A white, X-shaped sign or “crossbuck” is located at the railroad crossing. This sign has the same meaning as a “yield” sign; therefore, you must yield to trains at crossings.

Work Zone Signs

Work zone signs are fluorescent orange and indicate some type of work is being performed on or alongside the roadway. Obey the work zone signs and be extremely careful when you see these signs. There may be other traffic control devices or flag persons to help direct you safely through the work zone.

If you are caught speeding or passing in a construction zone or work zone, you will be fined.

Guide Signs

These signs are square or rectangular, and are green or brown with white lettering. They show direction and distance to various locations such as cities, airports, and state lines, or to special areas such as national parks, historical areas, and museums.

Service Signs

These signs are square or rectangular, and are blue with white letters or symbols. They show the location of various services, such as rest areas and hospitals.

Route Signs

The shape of route signs indicates the type of roadway: interstate, United States, state, or county.

Emergency Reference Markers

Emergency reference markers are mile markers placed along the outside shoulder to mark the edge of the roadway and convey information to drivers about their location on the interstate for navigation and emergency situations. The reference markers are located every two-tenths of a mile, so motorists will always be in sight of a sign. They tell the direction of travel and route number.
