An eight-sided red sign means "stop."

A broken yellow line alongside a solid yellow line means that traffic in the lane next to the broken line may cross the line to pass, while traffic in the lane next to the solid line may not.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This sign tells drivers that it is prohibited to make a U-turn.

When encountering a flashing yellow light at an intersection, you should slow down and proceed with caution. You do not need to come to a complete stop when approaching a flashing yellow light.

If it feels like your tires have lost contact with the surface of the road, you should ease your foot off the gas pedal and stay off the brakes. Do not try to stop or turn until your tires are gripping the road again.

When parking downhill, turn your front wheels toward the curb or edge of the road. When parking uphill on a road without a curb, turn your wheels toward the edge of the road. When parking uphill on a road with a curb, you must turn your front wheels away from the curb.

When you follow so closely behind a truck that you cannot see the truck driver’s side view mirrors, the trucker cannot see you and has no way of knowing you are there. Tailgating a truck, or any vehicle, is dangerous because you take away your own cushion of safety if the vehicle in front of you stops quickly.

Drivers making a left turn must yield to all vehicles approaching from the opposite direction. This includes bicycles and motorcycles.

If an oncoming driver fails to dim their high beams, you should avoid looking directly at the headlights. Instead, look toward the right edge of your lane and watch the oncoming vehicle out of the corner of your eye.

Alcohol slows your reflexes and reaction time, reduces your ability to see clearly, and makes you less alert. As the amount of alcohol in your body increases, your judgment worsens and your driving skills decrease. You will have trouble judging distances, speeds, and the movement of other vehicles.

A reflective orange triangle on the rear of a vehicle means it travels only at slow speeds. You may see this sign on roadwork equipment, farm vehicles, or horse-drawn wagons and carriages. It appears as a solid orange triangle during the day and a hollow red triangle at night.

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.

Alcohol is a depressant that dulls your judgment and makes your reflexes unreliable.

A three-sided yield sign indicates that you must slow down and be ready to stop, if necessary, to let any vehicle, bicyclist, or pedestrian pass before you proceed. In this case, you do not have the right-of-way.

When the center of the road is marked by a solid yellow line beside a broken yellow line, passing is permitted from the side next to the broken line and prohibited from the side next to the solid line.

When merging onto a freeway, you should enter at or near the speed of traffic.

When facing a green light, you must yield to pedestrians and vehicles already in the intersection. Drivers must yield to pedestrians when turning on a steady green signal.

Any amount of alcohol acts as a depressant, slowing the function of the nervous system. It will reduce a person's alertness and ability to concentrate, increase their reaction time, and drastically reduce their coordination.

Use high beams on open roads, which are unlit by streetlights, in order to see persons or vehicles ahead. You must change to low beams at least 500 feet before meeting oncoming vehicles. You must also change to low beam lights when following a vehicle at a distance of 300 feet or less.

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.

Regulatory signs provide notice to road users of traffic laws that must be obeyed. This particular sign tells you the maximum speed limit for the stretch of highway where it is posted. You may drive more slowly than the posted speed limit, based on road conditions, but it is illegal to drive any faster than the posted speed limit.

Dashed yellow lines separate single lanes of traffic moving in opposite directions. Passing is allowed when there is no oncoming traffic in the passing lane.

The color orange is used only for construction and maintenance warning signs.

Driving during the first half hour of rainfall is dangerous because roadways become extremely slippery when the water mixes with oil and other chemicals on the road surfaces that have not yet washed away. Use extra caution when driving on slippery roads.

Never pass within intersections or at other intersecting points, such as parking lot entrances and alleyways. Any time your view is blocked by a curve or a hill, you should stay in your lane and assume that there is an oncoming vehicle just out of sight. Wherever signs and/or pavement markings permit passing other vehicles, you will have to determine whether or not you have enough space to pass in a safe manner.
