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

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.

Driving at night is more dangerous than driving during the day for several reasons. It is harder to see in the dark, you may be temporarily blinded by the glare from other vehicles' lights, and there are likely to be more drivers on the road who are tired or under the influence.

This sign is posted on one-way streets and other roadways where a driver is not allowed to enter. A driver may see this sign if attempting to enter an expressway ramp in the wrong direction.

Distractions cause drivers to react more slowly to traffic and hazards on the roadway. Distracted driving is never safe.

If your vehicle begins to skid, do not use the brakes. Braking could make the skid worse.

A motorcycle is a full-size vehicle with the same privileges as any other vehicle on the roadway. You should allow a motorcyclist a full lane width. Although it may seem as though there is enough room in the traffic lane for a larger vehicle and a motorcycle, remember that the motorcycle needs room to maneuver safely.

Make room for vehicles that are entering a freeway. If possible, merge into the next lane to create a gap for the incoming vehicles. If you cannot merge, adjust your speed to allow for the vehicles to enter traffic as smoothly and safely as possible.

When entering the interstate on a short entrance ramp where there is no acceleration lane, speed up only after you have identified a gap in traffic. In general, you should be stopped while waiting for a gap to appear.

A green arrow has the same meaning as a circular green traffic light, but traffic in the indicated lane must turn in the direction shown by the arrow.

Railroad crossings are always dangerous. Drivers should always look and listen for trains approaching from either direction on all railroad tracks. Always follow the directions indicated by signs, signals, and flaggers. Never proceed past a railroad crossing until you are certain it is safe to do so.

To avoid contributing to chronic traffic congestion, you should not "rubberneck." That is, you should not slow down to look at out-of-the-ordinary things.

As driving speeds increase, the chance of a fatality in the case of a collision increases. If you are going faster than 80 miles per hour, you have almost no chance of living through a crash. The speed you drive affects your stopping distance, so you should increase your following distance as you increase your speed.

Even if your vehicle is properly equipped with mirrors, there are blind spots that cannot be seen by using the mirrors. Before changing lanes, look over your shoulder to check these areas.
