Warning signs are usually yellow with black markings. This sign warns drivers that they are arriving upon a fork in the road and they must bear either right or left.

A driver’s ability to safely operate a vehicle may be impaired at any BAC level, even a level lower than the legal limit. Any amount of alcohol can affect one’s judgment and physical coordination. Driving under the influence of even a small amount of alcohol can lead to criminal charges.

Passing on the right is permissible only if it is possible to do so without driving off the roadway. Never pass another vehicle on the shoulder because the other driver will not expect you to be there and may pull off the road.

Large vehicles require longer distances to stop and accelerate than smaller vehicles do. Making a sudden stop in front of a large vehicle is dangerous because the other driver may not be able to stop in time to avoid a collision.

Even if the light is green, you may not enter an intersection unless you can get completely across before the light turns red. If you block the intersection, you can be cited.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

Factors affecting a person's absorption of alcohol include the person's weight, their biological sex, the amount of food in their digestive tract, and the number of alcoholic beverages they have consumed. The only thing to do to remove alcohol from a person's system is to wait.

You should always signal when moving your vehicle to the right or left. On an interstate, you should stay in the right lane if you are moving more slowly than the surrounding traffic. It is illegal to back up or make a U-turn on interstate highways, so if you miss your exit, you should proceed to the next exit.

Holding a driver license is not a right. It is a privilege that must be earned and maintained.

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.

You may never drive off the paved or main-traveled portion of the road and onto the shoulder to pass another vehicle.

Do not pass unless you have enough space to return to the driving lane. Before you return to the driving lane, be sure you have enough room between yourself and the vehicle you have passed. When you can see both headlights of the passed vehicle in your rearview mirror, it is safe to return to the driving lane.

You must stop at a railroad crossing where signs, warning devices, or flaggers warn you of the presence of a train. It is illegal to drive around lowered gates.

This sign marks a one-way road, entrance, or exit. If you are facing this sign, traffic is coming toward you. Turn around if you are driving toward this sign.

You must not pass a vehicle that is stopped at a crosswalk. There may be pedestrians crossing the street that you cannot see. Instead, stop, proceeding only after all pedestrians have crossed.

Yellow lines separate lanes of traffic moving in opposite directions. A broken yellow line next to your driving lane means that you may pass.

If a traffic signal is displaying a steady red arrow, traffic in the indicated lane may not proceed in the direction shown by the arrow. Drivers must come to a full stop and wait for a green signal to proceed.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

Even if the signal is green, you must not enter an intersection unless you can get completely across before the light turns red. If you block the intersection, you can be cited.

Downward-facing triangular signs mean drivers must yield. When approaching a yield sign, slow down to a speed that is reasonable for existing conditions and stop if necessary. If you must stop, do so at a marked stop line, if it exists.

If you begin to skid on a wet or icy road, take your foot off the accelerator, stay off the brakes, and turn your steering wheel in the direction of the skid. However, if you have anti-lock brakes, you should apply your brakes firmly and steer straight ahead.
