When entering any roadway, you must be aware of traffic conditions. Use your side mirror and look over your shoulder to help you see and anticipate traffic when entering a freeway.

A white rectangular sign indicates that you must obey the stated rule. This sign means that drivers should not pass other vehicles for any reason.

This sign means drivers cannot make a left turn. It is unsafe and unlawful to make a left turn at an intersection where this sign is posted.

This sign warns a driver of a change in direction or a narrowing of the road. A driver may find several of these signs on the outside of a sharp curve or on approaches to a narrow bridge.

When planning to back up your vehicle, check behind the vehicle before getting in. Children and small objects may be difficult or impossible to see from the driver’s seat.

To prevent skidding on slippery surfaces, avoid especially slippery areas, such as ice patches, wet leaves, oil, or deep puddles. The safest surface for driving is a dry, solid surface.

Before driving, adjust the driver's seat so you are able to see the pavement 12 to 15 feet in front of your vehicle. Your chest should be located 10 to 12 inches from the center of the steering column and your shoulders should be no lower than the top of the steering wheel.

The only way to remove the effects of alcohol from the body is to let time pass. Eating, drinking coffee, or taking a shower will not speed up this process.

Warning signs are usually yellow with black markings. This sign warns drivers that they are arriving upon a fork in the road and they must bear either right or left.

Blind spots are areas that a driver cannot see if they look in their mirrors. Large trucks have large blind spots that drivers of other vehicles should avoid.

A double solid yellow line down the center of a road indicates that traffic is moving in opposite directions and that passing is not allowed from either direction.

If you miss your turn or exit, do not back up in the travel lane or on the shoulder. Continue to drive to the next exit or crossroad. Drivers do not expect a vehicle to be backing toward them on the roadway and doing so will likely cause a collision.

It is illegal to cross the centerline to pass when driving on hills, in curves, and in other locations where you cannot see ahead far enough to pass safely. You may not pass at street crossings, at railroad crossings, where signs indicate no passing zones, or where a solid yellow line is next to your lane. You may not pass when the vehicle in front of you has stopped for a pedestrian or when driving in work zones where passing would be hazardous.

This is a low clearance warning sign. It indicates the distance from the road surface to the bottom of a bridge or overpass (in this case, 12 feet, 6 inches).

Watch for any pedestrian who may cross your path. If you see pedestrians near the road where you are driving, slow down and be prepared to stop, if necessary.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

Legal medications, both prescription and over-the-counter, can impair your ability to drive. They can be particularly dangerous when used in combination with alcohol.

While airbags provide supplemental protection for adults in the event of a crash, they pose a severe safety risk for children. Anyone age 12 or under should sit in the back seat of a vehicle with airbags.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

Always be aware of what is happening around your vehicle. Constantly observing your surroundings to the front, sides, and rear of your vehicle will help you see problems that may require you to change speed or roadway position.

Legal medications, both prescription and over-the-counter, can potentially impair your ability to drive. Always consult with your doctor or pharmacist if you have questions about how a particular drug or drug combination will affect your ability to drive. You should particularly make a point of talking with your doctor if they give you a prescription for a tranquilizer or sedative.

Every 0.02 percent increase in blood alcohol concentration nearly doubles a driver's risk of being in a fatal crash.

Every time you want to change lanes or otherwise move your vehicle to the right or left, signal to alert other drivers to your intentions. Always check your mirrors and turn your head to check your blind spot before attempting any lateral move.

Large trucks take longer to stop than other vehicles traveling at the same speed. The average passenger vehicle traveling at 55 mph can stop within 400 feet. However, a large truck traveling at the same speed can take almost 800 feet to stop.

You must come to a complete stop at a steady or flashing red traffic light. You must always obey instructions given by officers directing traffic, regardless of any posted signs or traffic signals.

If your vehicle has a two-part seat belt system, be sure to wear both the lap belt and the shoulder belt. Wearing either part alone greatly reduces your protection. If you have an automatic shoulder belt, be sure to buckle your lap belt as well.

In rainy weather, you should lower your speed to reduce the risk of hydroplaning. Driving too fast may cause your tires to ride up on the water and lose contact with the surface of the road, making it very difficult to control your vehicle.

Glance at your speedometer about once every minute to ensure that you are driving at a safe and legal speed. This should become a habit.

Yellow signs with black markings are used to warn drivers about upcoming hazards or special conditions. Round signs are used only to warn about upcoming railroad crossings.

Use low beam headlights when driving in fog, rain, or snow. High beams may reflect off of the weather and make visibility even poorer.

A wet, slippery road does not allow your tires the traction they need, so it is necessary to drive more slowly on a wet road than you would on a dry road. To reduce the risk of skidding, you should avoid fast turns or stops.

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.

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.

Low beam headlights should be used in fog, rain, and snow. The light from high beams will reflect back to the driver under these weather conditions, causing a glare that will make it difficult to see ahead.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns that you are leaving a separated one-way highway and will soon be driving on a two-way highway.

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.

Keep a space between your vehicle and parked vehicles. A person may step out of a parked vehicle or out from between the parked vehicles without looking. A driver may begin moving their vehicle before realizing you are there.

If you are parked parallel on the right-hand side of the street, turn on your left turn signal and look over your left shoulder before moving back into traffic. If you are parked parallel on the left-hand side of a one-way street, turn on your right turn signal and look over your right shoulder before moving back into traffic.

Warning signs are usually yellow with black markings. This sign warns that the divided highway ends ahead. Prepare to change lanes or shift lane position.

This sign indicates that there is a crossroad ahead.
