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

This sign indicates that the road ahead turns sharply to the right and then sharply to the left.

A solid red arrow in a traffic signal means the same thing as a circular red traffic light. When an arrow is red, traffic in the indicated lane must stop and may not turn in the direction that the arrow is pointing.

Safe use of the interstate demands drivers be constantly alert and capable of driving at high speeds.

Compared to signs and other roadside objects, pedestrians are hardest to see at night.

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

A flashing yellow light means that you should slow down, check for cross traffic, and proceed with caution.

This sign alerts you to the possibility of traffic merging into the main stream of travel. After checking to your side and rear, you should move into another lane, if possible, to allow merging motorists a clear path.

This sign indicates that there is merging traffic entering from the right.

A driver must yield the right-of-way to a pedestrian within a crosswalk. The driver should wait until the intersection is clear to proceed.

Large vehicles have large blind spots to the rear. If you are behind a large vehicle, it is very likely that the driver does not know you are there. Because of this, if you need to pass behind a large vehicle that is backing up, it is always the safest option to wait for the truck's backup maneuver to finish before you pass.

When exiting an expressway, it is important to be alert to other traffic moving nearby. Be sure to look at the new posted speed limit and check your speedometer. It is unlikely that you will be exiting onto a road with a speed limit as high as the one found on the expressway.

Warning signs are usually yellow with black markings. This sign indicates that there is a steep hill ahead. Slow down and be ready to shift to a lower gear to control your speed and protect your brakes from damage.

Drivers should reduce their speed as they pass bicyclists, as air movement from a passing vehicle can easily affect a bicyclist's balance.

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.

Consuming alcohol and other drugs together can increase the impairing effects of both. For example, having one drink while you are also using a cold remedy could affect you as much as several drinks would when being consumed separately from any medications.

Being under the influence of alcohol affects your judgment. Good judgement is necessary to react appropriately to things that you see or hear while on the road. Even if you are below the legal blood alcohol limit, consuming any amount of alcohol is likely to affect your ability to drive safely.

You may cross a single solid line to pass other vehicles or change lanes, but only if obstructions on the road or in traffic make the lane change necessary.

Under ideal driving conditions, you should maintain a following distance of at least two seconds. If roads are slippery, your following distance should increase to at least three or four seconds. Any time conditions are less than perfect, you should increase your following distance.

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.
