To prevent drowsiness on long trips, you should schedule regular stops. Give yourself time to rest and stretch, even if you are not feeling tired.

A flashing yellow light means that you should proceed through the intersection slowly and with caution. Scan your eyes across traffic in both directions.

Alcohol negatively affects many skills needed for safe driving, including your reaction time and ability to see clearly. It can also harm your judgment of speed and distance, lower your inhibitions, and make you more prone to taking chances.

This sign warns that there is a steep hill ahead.

Yield the right-of-way to the driver on your right at a four-way intersection if you both arrive to the intersection at the same time. You may then proceed when it is safe to do so.

Adjust the inside mirror so you can see the entire rear window from the driver's seat. You should have to move only your eyes, not your head, when using this mirror.

"No zones" are the large blind spots around trucks and other large vehicles. Drivers of smaller vehicles should avoid lingering in "No zones."

This sign indicates that there is a Y intersection ahead. You must bear either to the right or to the left.

A "No stopping" sign means you can only stop to obey a traffic signal, to obey a police officer, or to prevent a conflict with another vehicle.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

"Reduced speed" signs inform drivers that they must reduce their speeds. If a new speed limit is posted on one of these signs, the new speed limit begins at the sign.

A red flashing traffic signal has the same meaning as a stop sign. When approaching a red flashing signal, come to a complete stop and proceed when it is safe to do so. A stop sign may sometimes also be posted where this signal is located.

One strategy to avoid driving while impaired or intoxicated is to arrange for a ride home with a friend who does not drink. Drinking coffee or taking a cold shower cannot reduce your blood alcohol content or reduce the effects of alcohol. On average, it takes about an hour for the body to eliminate the alcohol from a single drink.

This sign warns that the road is slippery when wet.

You should avoid making any sudden changes in speed or direction when driving on a slippery surface. Reduce your speed on slippery roads and do not use cruise control.

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

Backing requires extra caution because it is difficult for drivers to see behind their vehicles. Before entering a vehicle to back up, walk to the back of the vehicle to check for children and small objects.

Your blood alcohol content (BAC) depends on how much alcohol you drink, how much time passes between drinks, and your weight. Eating before or while you drink helps slow the absorption of alcohol somewhat, but it cannot prevent intoxication or impairment if you have too much to drink.

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

Do not drive in someone else’s blind spot. Move forward or drop back so that the other driver can see you.

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.

When passing a school bus that is stopped on the opposite side of a divided highway, drivers may continue driving. If the highway is not separated by a median or divider, drivers on both sides of the street must stop.

If you experience a tire blowout, take your foot off the gas pedal and do not immediately apply the brakes. Gradually slow down before gently applying the brakes and pulling off the side of the road.

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.

At intersections that are controlled by signs or signals and at intersections that are uncontrolled, the driver on the left must yield the right-of-way to the driver on the right when two vehicles arrive to the intersection at the same time.

Always signal your intentions when changing lanes, turning, or pulling away from a curb. Do not allow yourself to become lazy and form the bad habit of not following this law.

Crosswalk lines show pedestrians where to safely cross a road or street. Crosswalks may be marked by horizontal lines, vertical lines, or a combination of the two. You must always stop for pedestrians who are in a crosswalk.

If there is an available passing lane, you may pass on the right of a vehicle or bicycle that is turning left or waiting to turn left. It is also legal to pass on the right when driving on a multilane road with two or more lanes traveling in the same direction. You may never drive off the pavement or main-traveled portion of the road to pass another vehicle.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential traffic merging from the right. Drivers should prepare to allow the traffic to merge safely.

If a steady yellow light appears when you are already within an intersection, you should continue through the intersection carefully.

Speed limit signs indicate the maximum or minimum safe speed that is allowed to be driven on a roadway. The maximum limits are for ideal conditions and you must reduce your speed when conditions require it.

This sign indicates that a divided highway begins ahead. The road will split into two one-way roadways separated by a median or divider. You must keep to the right.

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.
