Drivers must respect and cooperate with all other road users and conform to specific rules in order to maintain order and to avoid crashes. When encountering an aggressive driver, it is safest to just get out of their way. Always avoid competing with other drivers.

When driving in a work zone, adjust your speed for the traffic conditions and don't follow other vehicles too closely. Be attentive to workers and machines in the work zone.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

In foggy or misty conditions, you should not use your headlights on their high beam setting because the light will be reflected back into your eyes.

Before returning to your original lane after passing, you must make sure you are not dangerously close to the vehicle you have just passed. When you can see both of the vehicle's headlights in your rearview mirror, you may have enough room to return to the lane.

When you see any signs indicating a nearby railroad crossing, you should slow down, look for a train, and be ready to stop. If the red warning lights are flashing or the gate is down, you must stop 15 to 50 feet before the railroad tracks. Do not try to go around the gate.

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.

A broken yellow line alongside a solid yellow line means that passing is allowed from the lane on the side next to the broken line.

If a railroad crossing has no warning devices or only a crossbuck sign, you should slow down, look in both directions of the track, and listen for a train or railroad equipment. Only proceed with caution across the tracks when it is safe to do so.

Some warning signs have a fluorescent yellow-green background. These signs warn of upcoming conditions, including roads with curves and sharp turns.

You may not be able to drive well if you are worried, excited, crying, angry, or depressed. Emotions can distract you from your driving because your mind is focused on something else. Take time to calm down and get focused before driving.

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

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 always signal before turning or changing lanes. You should keep your wheels straight while waiting to make a left turn. If another vehicle hits you from behind, this ensures that you will not be pushed into oncoming traffic.

A flashing yellow light means that you should proceed through the intersection slowly and with caution. Scan your eyes across traffic in both directions.

Pedestrians should not enter a street or crosswalk when vehicles are approaching. Though pedestrians have the right-of-way in crosswalks, a vehicle approaching from a close distance may not have the time to stop before entering the crosswalk.

If your vehicle enters a skid, you should take your foot off of the brake and steer in the direction that you want to go. For example, if the rear of your vehicle is skidding to the left, you should steer to the left. This will help bring the front of the vehicle in line with the rear, thereby straightening out the vehicle's overall direction.

If stopped by law enforcement while driving a motor vehicle in the District of Columbia, you will be responsible for providing your valid driver license, vehicle registration, and proof of insurance. Failure to comply may result in a fine and/or arrest.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that a traffic signal is ahead and drivers should prepare to react to a yellow or red light.

A "No stopping" sign means you can only stop to obey a traffic signal, to obey a police officer, or to prevent a conflict with another vehicle.

If your vehicle begins to skid, remain calm. Steer in the direction that you want to go and try not to overcorrect.

This sign warns that the road ahead becomes slippery when wet.

Drive below the posted speed limit when safety demands it. Some traffic, weather, or visibility conditions may require you to drive as slowly as 10 miles per hour.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that the road ahead curves to the right and then to the left.

Rumble strips create noise and vibrations to warn drowsy or inattentive drivers that they are straying off of the road or are approaching a stop sign or signal.
