Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that drivers are about to encounter a divided highway.

This sign indicates that there is an intersection ahead. A road joins from the right.

This sign indicates that the overpass ahead has a low clearance. You should not proceed if your vehicle is taller than the height shown on the sign (in this case, 13 feet 6 inches).

Reducing your speed should be your first response to decreased visibility and dangerous road conditions.

You should increase your following distance when you are behind a large vehicle that blocks your vision, when driving in bad weather or heavy traffic, when exiting an expressway, when behind a motorcycle or bicycle, and if someone is tailgating you.

Your vehicle's brake lights indicate to other drivers that you are slowing down or stopping. Your brake lights should always be in working order when you are driving on any roadway.

This sign is used with a traffic signal to tell drivers that left-turning traffic does not have the right-of-way and must instead wait for oncoming traffic to clear.

A double solid yellow line down the center of a two-way road means that it is prohibited for traffic from either direction to cross the center to pass.

Any time you want to change lanes, you should properly signal your intentions well in advance, check your mirrors, and check your blind spot. You can check your blind spot by glancing over your shoulder in the direction that you plan to move.

If your vehicle breaks down on the highway, you should signal before carefully exiting the roadway and turning on your hazard flashers. Get as far off the road as possible and park in a location where other drivers can easily see you. Lift your hood to let other drivers know your vehicle is disabled.

The only way to avoid the risks of drinking and driving is to decide before you start drinking that you are not going to drive. Because alcohol affects your judgement, it will be harder for you to make safe decisions after you have started drinking.

Fatigue and being under the influence of alcohol have similar effects on your ability to drive safely. For example, being awake for 18 hours impairs your driving about as much as a blood alcohol level of 0.05 percent. Being awake for 24 hours in a row has the same effect on your driving as a blood alcohol level of 0.10 percent.

Driving at night is more dangerous than driving during the day for several reasons. It is harder to see in the dark, you may be temporarily blinded by the glare from other vehicles' lights, and there are likely to be more drivers on the road who are tired or under the influence.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.

The combination of alcohol and drugs, in some cases, can increase the effects of both the drugs and alcohol. It can be unsafe to drive after consuming either alcohol or drugs and is even more dangerous after combining them.

You must always yield to pedestrians who are in or about to enter a crosswalk. Be alert to pedestrians when driving across intersections or turning.

When you are approaching an emergency or police vehicle that is stopped on the right side of the road with its lights flashing, immediately reduce your speed and proceed with caution. If you are traveling on a road that has two or more lanes traveling in the same direction, you must merge into a lane that is not adjacent to the emergency vehicle, if it is safe to do so.

Motorcycles are smaller and harder to see than cars. Because of their size, they are easily hidden in a car’s blind spot. It may be difficult to judge your distance to a motorcycle and difficult to tell how fast a motorcycle is moving, so always be alert and extra cautious when near a motorcyclist.

You should pass a bicyclist the same way you would pass any other vehicle, but not so fast or close to them that you throw debris in their face or blow them around with the draft of air from your vehicle. Allow at least 3 feet of space between your side mirror and the bicyclist, or at least 5 feet on higher speed roads or when there is a group of bicyclists. Honking unnecessarily may startle riders and make them more likely to crash.

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.

Persons who are upset, angry, or otherwise distracted by their emotions should take time to cool off before driving a car. Taking out frustrations or anger while driving is exercising very poor judgment and is very dangerous to both the driver and others on the road.

Do not use your high beam headlights when approaching or following another vehicle at night. Switch to the low beam setting to ensure the safety of everyone on the road.

You must yield to any transit vehicle that is signaling to pull back onto the main roadway after it has stopped to load or unload passengers. Change lanes, slow down, or stop to allow the bus safe re-entry into traffic.

When parking on a public road, you must park parallel to and within 18 inches of the curb or edge of the roadway. Your vehicle should be facing in the same direction as the traffic is moving on your side of the road.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential bicycle cross traffic.

A "No standing" sign means that you may only make a temporary stop to load or discharge passengers.

In general, vehicles at a four-way stop should proceed in the order that they arrive. However, if two vehicles arrive to the intersection at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

If a green arrow turns into a solid green light, you may still turn in the direction that the arrow was pointing but you must first yield to pedestrians and oncoming traffic.

It is against the law to consume or possess any alcoholic beverage while on a public road or sidewalk. Additionally, storing an open alcoholic beverage container in an area of a motor vehicle normally occupied by the driver or passenger is prohibited on any public road.

To turn left from multilane streets and highways, start from the left lane.

Construction and maintenance signs are orange-colored and are used to notify drivers of unusual or potentially dangerous conditions in or near work areas. This sign warns drivers that they are approaching a construction zone and that they should prepare to lower their speed and drive with extraordinary caution.

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

Situations where motorists are required to stop include approaching intersections with stop signs, approaching intersections where a red light is either flashing or illuminated, or any time when a traffic officer orders your vehicle to stop.

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

Use the entrance ramp to accelerate to the speed of freeway traffic and yield to traffic already using the freeway. Before entering traffic, use your mirrors and check your blind spots to verify that you have room to safely merge.

If a vehicle comes toward you with its high beams on, look away from the headlights and toward the right side of the road until the car has passed. This will keep you from being blinded.

All bicyclists have the same rights, duties, and responsibilities as drivers of motor vehicles. Motorists and bicyclists who do not obey traffic laws can be ticketed.

Yield to other drivers when making a left turn. Always yield to pedestrians and oncoming traffic, unless directed otherwise by signs, signals, flaggers, or officers.

When changing lanes or turning, signal your intentions well in advance. The law requires that you signal for at least 100 feet before you move your vehicle to the right or left. Before pulling away from a curb, always signal to inform passing drivers of your intentions.

Before you drive, always fasten your seat belt and make sure all your passengers are using seat belts or child restraints. Studies have shown that if you use seat belts, your chances of being hurt or killed in a traffic crash are greatly reduced. Children age 12 and under should always ride properly restrained in a rear seat. Never put a rear-facing infant restraint in the front seat of a vehicle with a front passenger airbag.
