This sign warns that the road is slippery when wet.

This sign is displayed on slow-moving vehicles.

Painted curbs indicate parking restrictions. When a curb is painted yellow, it indicates the presence of a loading zone, or another parking restriction.

When you drive, make sure each person in your vehicle wears a seat belt. In the event of a crash, a person without a seat belt becomes a flying object and a danger to each person in the vehicle.

When driving on an interstate highway, be aware of upcoming on-ramps. When traffic permits, move out of the right-hand lane to allow vehicles to enter from the on-ramps to your right.

Even after a train passes, watch out for a second train approaching on any track. Do not proceed until all gates have been lifted and all warning signals have stopped flashing.

A green light tells you that you can go through the intersection. However, you must first yield the right-of-way to traffic and pedestrians who are still in the intersection.

This sign warns that there is a flag person ahead. Always follow directions given by a flagger. Flaggers normally wear orange or yellow vests, yellow-green shirts, or bright jackets. They use paddles and red flags to direct traffic through the work zone and to let workers or construction vehicles cross the road.

You must never turn around while on or near any curve or hill. You may not be able to see oncoming traffic or pedestrians and may cause a collision.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

Crashes often happen because one driver does something that other road users are not expecting. You should communicate with other motorists, bicyclists, and pedestrians by doing things like signaling when slowing down, stopping, or changing direction. Use your emergency signals or horn when appropriate.

Painted curbs indicate parking restrictions. When a curb is painted white, it indicates that only short stops are permitted.

Before changing lanes, you should check your side mirrors and look over your shoulder to make sure it is safe to proceed.

When you park on a downward-facing slope, turn your wheels sharply toward the side of the road. This way, if your vehicle starts to roll downhill, it will roll away from traffic.

Before passing another vehicle, check your mirrors and blind spots. Before changing lanes, activate the appropriate turn signal. Re-enter the lane when you can see the front of the passed vehicle in your rearview mirror.

A broken yellow centerline means that a driver may cross the centerline to pass another vehicle on the left as long as there is no oncoming traffic. Drivers should never cross a solid yellow centerline in order to pass.

While it is always dangerous to drive too fast on slippery roads, this is especially true when driving in turns and curves. Be sure to approach them more slowly in slippery conditions than you would under normal circumstances.

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.

This sign marks a high occupancy vehicle (HOV) lane. HOV lanes are reserved for use by buses and vehicles with a driver and one or more passengers, as indicated on the sign.

When a steady yellow light appears on a traffic signal, you should prepare to stop. If you are already within the intersection, you should clear the intersection as quickly as possible.

A steady yellow traffic light indicates that the light will soon change to red. You should be prepared to stop for the red light, if it is safe to do so.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

An octagonal sign always means stop. When approaching a stop sign, you must come to a complete stop at the marked stop line and proceed only when it is safe to do so. If there is no stop line, stop before the crosswalk. If there is no crosswalk, stop before the intersection at a point from which you can see any oncoming traffic.

When passing another vehicle on a two-lane roadway, you must return to the right side of the roadway when there is enough room between you and the vehicle you have passed.

If you pass another vehicle on its right, do so only when conditions permit you to do so legally and safely. You may only drive on the shoulder of a road if an official has directed you to do so.
