Solid white lines are used to separate lanes traveling in the same direction (as well as to mark the right edge of the road). Broken white lines separate lanes traveling in the same direction and may be crossed to pass. Yellow lines separate lanes of traffic moving in opposite directions.

In many collisions with motorcycles, bicycles, and pedestrians, drivers reported that they were looking but still did not see the smaller vehicle or pedestrian. These can be more difficult to spot in traffic than passenger vehicles because they are smaller, may move faster, and have less noticeable lighting. To prevent collisions with these smaller and less protected road users, drivers should always be alert to the presence of motorcycles, bikes, and pedestrians.

Regulatory signs require drivers to obey an indicated instruction. Failure to comply is subject to penalty.

Your ability to handle dangerous traffic situations depends largely on searching for and identifying problems before meeting them. Looking far ahead of your vehicle does not mean you should simply stare at the center of the road. You need to continually scan the entire road, including the sides of the road.

If you hear a siren or an air horn close by but do not know exactly where the emergency vehicle is, safely pull over to the right side of the road and stop until you are sure it is not headed toward you.

A flashing yellow traffic light means drivers should slow down and proceed with caution.

This sign indicates that a divided highway begins ahead. The road will split into two one-way roadways separated by a median or divider. You must keep to the right.

This sign prohibits U-turns. Do not make a U-turn where this sign is posted.

Any turn should be made from the lane that is closest to the direction you want to travel and into the lane closest to your original lane.

Crossbuck signs tell drivers to yield to trains at a railroad crossing. Drivers should not try to outdrive a train.

Be prepared to reduce your speed and use caution when directed to do so by a sign, flagger, or law enforcement officer. Failure to do so is illegal and is dangerous to those working in construction zones.

A solid yellow line next to your lane means that passing is not permitted from your direction.

Before changing directions, you should signal for at least 100 feet.

Two solid yellow lines down the center of a two-way road mean that neither lane of traffic may cross the lines, unless they are turning off of the roadway. A driver can cross double yellow lines when turning into or out of a driveway or entrance to a business. No passing is allowed over a solid yellow line.

A steady yellow traffic light indicates that a red light is about to appear. Stop unless you are already within the intersection.

This sign (with the arrow below) indicates the location of a bicycle crossing/path. Drive with caution around this sign because bicycles likely regularly cross or ride beside traffic in the area.

This triangular sign is a "Yield" sign. When you see this sign, you must slow down to check for traffic and yield the right-of-way to pedestrians and approaching cross traffic. Stop only if it is necessary to do so.

Consuming even a small amount of alcohol will impair your vision, judgment, concentration, and coordination.

Marijuana-infused food can affect a consumer at a much slower rate than marijuana that is smoked. Smoking marijuana can damage a consumer's lungs. Ingesting marijuana in any form can negatively affect a driver's ability to operate a motor vehicle.

Pennant-shaped signs usually indicate no passing zones. Text will also be on the sign to confirm that it is a no passing zone.

To prevent hydroplaning, you should ensure that the tires on your vehicle have good tread depth and are inflated to the proper pressure. Reduce the speed of your vehicle when driving in the rain. Hydroplaning occurs most frequently at higher speeds.

To complete a turn safely, you should activate your turn signal three to four seconds before your turn.

It is prohibited to park on the shoulder of a freeway, except in an emergency.

When approaching a flashing red signal, you must stop and yield to all traffic that does not have to stop.

Alcohol is a depressant drug that slows the activity of the brain and reduces the skills that you need for safe driving. Drinking alcohol results in slowed reaction time and impaired judgment.
