A flashing red traffic signal has the same meaning as a stop sign. At an intersection with a flashing red light, you must come to a complete stop, look both ways, and proceed only after the intersection is clear.

A solid yellow arrow means that the protection of a green arrow is ending. If you are turning in the direction of the arrow, you should prepare to stop and yield the right-of-way to oncoming traffic before turning.

When turning left at an intersection, you must yield to oncoming bicycles in the same manner that you would yield to oncoming motor vehicles. Keep your wheels straight while waiting to turn and proceed when the way is clear of traffic and pedestrians.

When driving, do not develop a fixed stare. Frequently check your rearview mirrors so you know the positions of vehicles near you.

You should use low beam headlights when driving in fog, rain, or snow.

Drivers must slow down when approaching an intersection. If a clear view of cross traffic is obscured, a driver should come to a stop and inch forward until they can see clearly in both directions.

When passing, you should not return to your original lane until you can see both headlights of the passed vehicle in your rearview mirror. Always check your blind spots before moving back into your original lane.

You are required to use your headlights during the day when visibility is reduced to 500 feet or less. When you first turn on your headlights, be sure they are adjusted to the low beam setting. Using high beams in fog or rain will cause the light to reflect back into your eyes, lowering visibility even more.

The speed at which you should drive your vehicle depends on road conditions, the weather, and the legal speed limit. You may never drive above the legal speed limit. Decrease your speed when anything makes conditions less than ideal.

Although the right-of-way rules provide a guide to determine who should yield the right-of-way at an intersection, no one should assume they automatically have the right-of-way. The situation and circumstances at an intersection must always be considered. Drivers should yield their legal right-of-way if it can help prevent a collision.

Being fatigued while driving is similar in danger to driving under the influence of alcohol. If you begin to feel tired while driving, the best thing to do is to stop driving.

This sign indicates that workers may be on or very close to the roadway ahead, so you should take special care when traveling through the area.

Lane use control signals are used when the direction of the flow of traffic in a specific lane changes throughout the day. They are used to show which lanes of traffic are open and closed, as well as to show if toll booths are open or closed. When a lane control signal contains a green arrow, drivers may drive normally in the indicated lane.

You must do everything you can to prevent striking a pedestrian or another vehicle, regardless of the circumstances. It is the driver’s basic responsibility to be alert to pedestrians and to yield the right-of-way to all pedestrians, even if the pedestrian is crossing the street where they should not be.

Directions given by traffic officers take precedence over signs, signals, and pavement markings. People authorized to direct traffic include police officers, fire police, highway work area flag persons, and school crossing persons.

Regulatory signs are white, rectangular signs with black markings. Drivers must obey the instructions posted on all regulatory signs. Where this sign is posted, it is prohibited for drivers to pass one another.

A flashing red light at an intersection means drivers are required to come to a complete stop, yield to traffic and pedestrians, and proceed when the way is clear. The same is true at a stop sign.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

This signs indicate that U-turns are prohibited in the location where it is posted.

The maximum speed limit should be driven only under ideal conditions. You must reduce your speed when safety requires it, such as during snowy, icy, rainy, or foggy weather.

If you encounter an aggressive driver, you should make every attempt to get out of their way. You should avoid making eye contact with a hostile driver. Challenging a hostile driver by speeding up may only make them angrier, thereby increasing their danger.

If you stop along the road at night, turn on your emergency flashers and leave your low beam headlights turned on. Be sure that other road users will be able to clearly see your vehicle.

You should allow more space in front of your vehicle than usual when you are stopped on an uphill slope. If the vehicle in front of you rolls backward toward your vehicle when traffic begins to move again, it is less likely that there will be a collision.

You must yield the right-of-way to police cars, fire engines, ambulances, or any other emergency vehicles using a siren or air horn and a red or blue flashing light. Follow any instructions given over the emergency vehicles' loudspeakers. Emergency vehicles often follow each other so you should proceed only when you are certain the way is clear.

The average person’s body will process about one alcoholic drink in one hour. However, many factors play a part in determining how impaired a person will become when consuming alcohol, including the amount of alcohol consumed, how fast it is consumed, and a person’s body weight, food intake, and general health.
