A flashing red light means that you must come to a full stop, and then proceed when the way is clear.

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.

Unless otherwise posted, the speed limit on blind curves is 20 mph. If a posted sign indicates otherwise, follow the speed limit on the posted sign.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This warning sign indicates that a traffic signal is ahead and drivers should prepare to react to a yellow or red light.

When stopped for a traffic violation or at an equipment check, the driver is responsible for producing their license, proof of registration, and proof of insurance. Drivers are required to have all three of these documents in a vehicle when it is being driven.

When you are approached by an emergency vehicle that is using its lights, sirens, and/or other warning devices, you must immediately drive to the right side of the road and stop.

If a green arrow is shown with a red light, you can only drive in the direction of the arrow and only if the intersection is clear.

Many over-the-counter medications can affect your ability to drive safely. If you take medication, even a remedy for colds or allergies that is not prescribed, check the label for warnings about its effects. If you are unsure, ask your doctor or pharmacist about driving while on the medication.

A flashing red traffic light means the same thing as a stop sign. You must come to a complete stop, yield to cross traffic and pedestrians, and then proceed when the way is clear.

Warning signs advise drivers of potentially hazardous conditions. For your own safety, obey warning signs. Disregarding the information provided by a warning sign may result in an accident due to your negligence.

Some travel lanes are designed to carry traffic in one direction at certain times then in the opposite direction at other times. These lanes are separated by a barrier or marked by double broken yellow lines.

This sign indicates that you are approaching a railroad crossing.

A yield sign means that you must slow down and yield the right-of-way to traffic in the intersection or roadway you are entering.

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.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming curve in the road.

Yield the right-of-way to service vehicles and maintenance equipment engaged in work on roadways. Use extra caution in approaching, overtaking, or passing maintenance vehicles and snowplows. Because of their traveling speed and size, snowplows tend to create large clouds of blowing snow that conceal the plow, making it invisible.

A speed limit is the maximum or minimum legal speed you can travel on a road under ideal conditions. You may drive more slowly than the posted speed, but it is illegal to drive any faster. You must drive more slowly where signs or signs indicate a school zone or work zone speed limit. If conditions such as road construction or bad weather make the posted speed unsafe, drive under the speed limit.

Work zone signs are orange and indicate that some type of work is being performed on or alongside the roadway. Be extremely careful when you see these signs.

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.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

This sign indicates that the road ahead curves to the right and then to the left. You should slow down to be able to negotiate these curves safely.

Because hydroplaning is caused by driving too quickly in wet conditions, the risk of it happening can be reduced by driving more slowly.

You should always turn from the lane that is closest to the direction you want to go. Turn into the lane closest to your previous lane.

If you drive past these signs, you are going the wrong way and are at risk of a head-on collision. You should cautiously turn around.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign warns drivers to be extra careful when the pavement is wet because the road may become slippery, making vehicles more difficult to control.
