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.

HAWK signals are used at pedestrian crossings. If the signal changes to a solid red, drivers should come to a complete stop.

You must not drive at a speed that is faster than is reasonable and prudent. You must drive at a speed that is appropriate for the area where you are driving, the type and condition of surrounding traffic, the presence of pedestrians, the weather, the quality of the road, and light conditions. You must drive within legal speed limits.

Round signs warn drivers of an upcoming railroad crossing area. Drivers should use extra caution when approaching a railroad crossing.

Some regulatory signs prohibit certain actions. These signs are rectangular and white with red and black markings. A red circle and slash on top of a black symbol indicates that the specified action is forbidden.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

This sign warns that especially slippery conditions exist when the road is wet.

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

Pentagonal signs indicate that you are in a school zone. Be extra alert to children and pedestrians when driving near a school.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that parking is not permitted.

A green light tells you that you can go through the intersection. However, you must first yield the right-of-way to traffic and pedestrians who are still in the intersection.

Both hands should be placed on the outside of the steering wheel at the 3 and 9 o’clock positions to maintain control of the vehicle. Placing your hands at the 2 and 10 o’clock positions is no longer recommended because it can be dangerous in a vehicle equipped with airbags.

It is unlawful for someone to drink from or possess an open container of alcohol while in the passenger area of a motor vehicle that is on a public road. Failure to adhere to this law will result in negative consequences for the driver.

This sign indicates that the overpass ahead has a low clearance. You should not proceed if your vehicle is taller than the height shown on the sign (in this case, 13 feet 6 inches).

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers turning left at a green light must yield to oncoming traffic and may complete the turn when it is safe to do so.

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

When making a left turn where there is approaching traffic, you must wait for the approaching traffic to go through before you turn. You may enter the intersection to prepare for your left turn if the light is green and no other vehicle ahead of you plans to make a left turn.

After an accident, do not move the injured unnecessarily. Unskilled handling can make serious injuries out of minor ones. Keep the injured warm until skilled help arrives. If there is severe bleeding, attempt to stop the flow of blood with direct pressure.

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

Driving while impaired or intoxicated is a serious traffic safety problem. Safe driving is not possible when you drink alcohol or take other drugs. Driving under the influence is dangerous both to you and to others on the road.

You should never pass if there is an oncoming vehicle in the passing lane, if your view is blocked by a curve or hill, at an intersection, before or on a railroad crossing or bridge, or in any other no passing zone. Unless you are on the opposite side of a multilane roadway with a median or shared center turn lane, you may not pass a stopped school bus that has its flashing red lights activated.

When you are tired, you cannot drive as safely as you can when you are rested. Your reactions and decision-making skills are greatly reduced. Break long driving periods into two-hour segments. If you become drowsy, pull off the road and rest.

The only way to be sure you will have enough time to react to mistakes made by other drivers is to leave plenty of space between you and the vehicles around you.

This sign indicates that hospital emergency services are located to the right.
