Guide signs, sometimes known as destination signs, have a green background and provide directional and mileage information to specific destinations. They can be a helpful resource when driving in unfamiliar locations.

If a traffic light at an intersection is not functioning due to a power outage, yield to other drivers in the same manner as you would when approaching a four-way stop. When it is your turn, proceed through the intersection with caution.

This sign indicates that the road ahead changes direction at an extreme angle (in this case, to the right). Before you reach such an extreme curve, you should slow down as much as you would when making a turn at an intersection.

Worn or bald tires can increase your stopping distance and make turning more difficult. Tires without adequate tread also increase the risk of hydroplaning.

When entering a freeway, use the on-ramp to accelerate to the speed of freeway traffic so you can blend in smoothly and safely. Entering traffic must yield to traffic already on the freeway.

If a driver's left arm and hand are extended upward, they are indicating that they intend to turn right. Adjust your driving accordingly if following a driver who is using this hand signal.

Reduce your speed when roads are snow-covered or icy. Doing this and increasing your following distance are the most important techniques for avoiding crashes under snowy or icy conditions.

As alcohol builds up in your system, it will slow your reactions, make you feel more confident, and cause you to make more errors.

You should not stop in a travel lane for any reason. Instead, keep moving until you can safely pull off of the road. If you miss your turn or exit, do not back up. Go to the next turn or exit or where you can safely turn around.

In rainy conditions, you should use your low beam headlights.

An eight-sided sign always means "stop." You must come to a complete stop and wait for any vehicles or pedestrians to clear the way before proceeding.

You must make a reasonable effort to find the owner of an unattended vehicle, or other piece of property, that has been damaged in a crash in which you were involved. If the owner cannot be located, leave your name, address, and license plate number in a note describing the crash.

You drive defensively when you identify dangerous driving situations and take action before an accident occurs. Defensive driving helps prevent conflicts with aggressive, offensive, discourteous, careless, inattentive, impulsive, ignorant, or intoxicated drivers or pedestrians.

When turning onto a street with more than one lane moving in the direction that you are traveling, turn into the lane that is closest to your previous lane. Do not change lanes when turning.

When parking on an incline where there is a curb, you should turn your wheels sharply to the left, away from the curb. This way, if your brakes fail, your vehicle will not roll into traffic.

Crossbuck signs tell drivers to yield to trains at a railroad crossing. Drivers should not try to outdrive a train.

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.

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

Alcohol dulls the parts of your brain that control inhibition, judgment, and self-control. As a result, you may feel stimulated, lively, and a bit giddy or foolish after consuming alcohol. Alcohol also impairs your reaction time, coordination, and balance. Your vision and ability to judge distance suffers after alcohol consumption, making it difficult to react to your surroundings.

You are required to use your headlights during the day when visibility is reduced to 500 feet or less. When you first turn on your headlights, be sure they are adjusted to the low beam setting. Using high beams in fog or rain will cause the light to reflect back into your eyes, lowering visibility even more.

The slow-moving vehicle symbol is a reflective orange triangle. Expect vehicles using this emblem to be driving at speeds of 25 mph or slower.

If a dashed yellow pavement marking continues up to and after an intersection, you may pass vehicles in the intersection. If there are no pavement markings in the intersection, or if there is a solid yellow line next to a dashed yellow line in the intersection, you may not pass in the intersection.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. If there is a flagger at a crossing, you must obey all of their instructions.

If your vehicle's turn signals do not work, you should use hand signals to indicate when you intend to change direction.

When driving an unfamiliar vehicle, take a few minutes before driving to familiarize yourself with the location and operation of the turn signals, hazard warning signals, headlights and beam selector, windshield wipers and washers, brakes, gear selector, and horn. Any defects should be corrected before the vehicle is driven.

You are required to stop at all railroad crossings when signals warn of an approaching train. These signals may include flashing red lights, a lowered crossing gate, a flagger signaling, or a train’s audible signal of warning. Do not attempt to go around a lowered gate.

Regardless of standard speed limit maximums set by law, state and local authorities may adjust speed limits in specific areas by posting speed limit signs. When it is reasonable and prudent, follow the posted speed limit.

If involved in an accident, you should stop your vehicle immediately. If possible, move the vehicle out of the way of traffic. Call the nearest police agency and ask for an ambulance, if necessary. Do not move the injured unnecessarily, but attempt to stop severe bleeding with direct pressure. Wait for emergency vehicles to arrive.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

Studies show that, when worn properly, safety belts greatly reduce your chances of being seriously injured in a crash. Seat belts are 60 to 70 percent effective in preventing fatalities in auto crashes.

If you approach an emergency vehicle, tow truck, or roadside assistance vehicle that is stopped with its lights flashing, you must change lanes to allow the vehicle extra space. If there is only one lane moving in your direction, or if changing lanes would be unsafe, you must slow down to a speed below the posted speed limit and give the stationary vehicle as much room as possible. Always slow down and be prepared to stop when you approach an emergency scene.

This sign warns that a traffic signal is ahead.

Emotions can have a great effect on your driving ability. You may not be able to drive well if you are overly worried, excited, afraid, angry, or sad. Stress can lessen your concentration on the task of driving. It is better to wait to drive than to risk driving while you are emotionally unstable.

As you approach a left turn, signal your intentions three to five seconds in advance. Continually check your rearview mirror as you gradually slow down. On a multilane road, move into the left lane before reaching the intersection where you plan to turn. Yield to traffic and pedestrians and turn when your path is clear.

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

This sign indicates the presence of a pedestrian crossing. You should watch for people entering a crosswalk or crossing your path. Slow down and be prepared to stop.

The average person’s body will process about one alcoholic drink in one hour. However, many factors play a part in determining how impaired a person will become when consuming alcohol, including the amount of alcohol consumed, how fast it is consumed, and a person’s body weight, food intake, and general health.

Warning signs are usually diamond-shaped with black markings on a yellow background. They alert drivers to upcoming hazards. This sign warns drivers to be extra careful when the pavement is wet because the road may become slippery, making vehicles more difficult to control.

Develop a routine for entering and leaving your car. Before switching on the ignition, buckle your safety belt and see that all passengers do likewise.

If there are two railroad tracks next to each other, watch for a second approaching train after one train passes. Do not begin to cross the tracks until you’re sure no train is approaching from either direction on either track.
