The more distance between your vehicle and others, the more time you will have to react if another driver makes a mistake. Keep a minimum following distance of four seconds when driving under poor weather and traffic conditions.

To avoid becoming fatigued while taking a long trip, stop every two hours for a short break. If you become drowsy, pull off the road and park in a safe place to take a nap, or find a room to stay for the night.

An octagonal (eight-sided) sign always means "stop." You must always come to a complete stop at this sign.

The more distance between your vehicle and others, the more time you will have to react if another driver makes a mistake. Keep a minimum following distance of three seconds under normal weather and traffic conditions. Increase your following distance when driving under unusual weather or traffic conditions.

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.

Low beam headlights should be used when driving in rainy or foggy weather. Even if they do little to help you see, low beams will make it easier for others to see you.

This sign warns of the presence of a hill ahead.

Most warning signs are diamond-shaped and yellow with black markings. These signs warn drivers about unexpected conditions that may not be readily apparent.

Yellow lines tell you that the traffic on the other side of the lines is moving in the opposite direction. You should never cross two solid yellow lines to pass from either direction.

When being approached by an emergency vehicle that is using its lights and/or sirens, you must immediately pull to the right side of the road and allow it to pass.

After a minor collision, move your vehicle off the traveled portion of the roadway, if possible. Do not leave the scene of an accident without identifying yourself and rendering assistance.

A round sign means you are approaching a railroad crossing. This sign is posted a few hundred feet in front of the tracks and tells drivers to slow down, look, listen, and prepare to stop.

You must stop when approaching a school bus that is displaying flashing red lights while stopped to pick up or drop off children. On a two-lane road, traffic moving in both directions must stop and remain stopped as long as the red lights near the top of the bus are flashing and/or the stop arm on the left side of the bus is extended.

If there is danger, you may need to sound a sharp blast on your horn. Do this when a child or any other pedestrian is about to enter into the street in front of your moving vehicle.

Railroad crossings are always dangerous. Drivers should look and listen for an approaching train coming from either direction before proceeding across the tracks. Watch for signals indicating an approaching train and never proceed until you are certain it is safe to do so.

This sign indicates that there is a crossroad ahead.

When you intend to back up, always check behind your car for bikes, tricycles, and small children before you get into your car. This is an especially important practice for drivers of larger vehicles, such as vans and trucks.

To keep your vehicle from rolling into traffic when parked facing uphill, turn your front wheels sharply away from the curb. If you are parking uphill on a street that has no curb, turn the wheels sharply toward the edge of the road.

If you are entering traffic from a driveway or private road, you should yield to drivers already on the public road. Merge safely into traffic when you are able to do so.

Hydroplaning occurs when there is standing water on a roadway. At speeds up to 35 mph, most tires will channel water away from the tire. As your speed increases past 35 mph, tires cannot channel the water as well and your tires may start to lose contact with the road and ride over the water like a set of water skis.
