This sign indicates that there is an intersection with a side road ahead.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

You must stop at a railroad crossing where signs, warning devices, or flaggers warn you of the presence of a train. It is illegal to drive around lowered gates.

Avoid "rubbernecking," or slowing down to look at collisions or anything else out-of-the-ordinary. This helps to relieve traffic congestion.

If you experience a sudden tire blowout, do not panic. Grasp the steering wheel firmly and take your foot off the accelerator to allow the vehicle to roll to a stop. Lightly apply the breaks when it is safe to do so. Do not move to the shoulder of the road until the car has slowed considerably.

To avoid being blinded when driving at night, do not look directly at the headlights of oncoming cars. Instead, look toward the right edge of the road until the oncoming driver has passed.

You may drive more slowly than the posted speed limit, based on road conditions, but it is illegal to drive any faster than the posted speed limit. Some conditions which require reduced speed for safety include approaching curves or hills where visibility is limited, driving on slippery roads, and driving on roads where animals and pedestrians are present.

When you are approaching a school bus that has stopped on the road with its stop signal arm extended and its red lights flashing, come to a complete stop. Remain stopped until the stop signal is retracted and the flashing lights are turned off.

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.

Regulatory signs provide notice to road users of traffic laws and must be obeyed. Where this sign is posted, making a right turn is prohibited.

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.

When driving on a country paved road, the statutory speed limit is 45 miles per hour. If a different speed limit is posted, follow the posted speed limit.

White lines between lanes indicate that the lanes are traveling in the same direction. Broken white line markings indicate that it is legal to pass another vehicle when safe.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers about the presence of traffic signals at an intersection ahead.

A driver must yield the right-of-way to a pedestrian within a crosswalk. The driver should wait until the intersection is clear to proceed.

Stop when a traffic signal is red. Remain stopped at a steady red light until the signal changes to green.

Drivers should use low beam headlights when driving in fog. High beams will reflect back at the driver, making it difficult to see.

At an intersection where traffic is not controlled by traffic signal lights, drivers are required to yield the right-of-way to pedestrians within any crosswalk, marked or unmarked. Even if there is no crosswalk, yield to the pedestrian.

Continuous hard braking on snow and ice can result in the locking of the front brake, causing a loss of steering. To avoid the need for excessive braking, make sure to maintain an appropriate speed for conditions.

You should drive more slowly at night than during the day because it is not possible to see as far ahead at night. You should make sure that you can stop within the area illuminated by your headlights.

Before you return to the driving lane when completing a pass, be sure there is a safe gap between your vehicle and the passed vehicle. When you can see both headlights of the vehicle in your rearview mirror, it is safe to return to the driving lane.

Because large commercial vehicles have large blind spots on each side, you should avoid driving beside them for long periods of time.

On rainy, snowy, or foggy days, it may be difficult for other drivers to see your vehicle. Under these conditions, headlights make your vehicle easier to see. If the weather requires you to turn on your windshield wipers, you must also turn on your low beam headlights.

Backing up is always dangerous because it is hard to see behind your vehicle. Use extra caution when backing up.

If there are oncoming vehicles to your left and a row of parked vehicles to your right, the best thing to do is to split the difference. Steer a middle course between the oncoming cars and the parked cars.

This sign is displayed on slow-moving vehicles.

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.

When a steady yellow light appears on a traffic signal, you should prepare to stop. If you are already within the intersection, you should clear the intersection as quickly as possible.

Eye fatigue is common when driving at night. This can be relieved by keeping your eyes moving from the center of the road to the sides, from near to far ahead, etc.

You must drive more slowly than usual when there is heavy traffic or bad weather. However, if you block the normal and reasonable movement of traffic by driving too slowly, you may be cited. You should match the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

To do your part to prevent road rage, you should follow laws, signs, signals, and pavement markings. Always signal your intention when changing lanes.

A diamond-shaped yellow sign warns of possible danger ahead. Orange signs, which are mostly diamond-shaped, are used to warn of possible dangers in or near work areas.

You should always slow down before entering a curve. You may not be able to see hazards ahead and braking in a curve may cause your vehicle to skid.

Although the right-of-way rules provide a guide to determine who should yield the right-of-way at an intersection, no one should assume they automatically have the right-of-way. The situation and circumstances at an intersection must always be considered. Drivers should yield their legal right-of-way if it can help prevent a collision.

Drivers must obey any instructions given by a police officer, even if the instructions contradict laws, signs, signals, or markings that would otherwise apply.

Reduce your speed and be prepared to slow down or stop for highway equipment. Driving carefully through work zones improves safety for drivers, pedestrians, bicyclists, and road workers.

If you see an emergency vehicle approaching while using its flashing lights, pull over to the right edge of the road and stop. Position yourself parallel to the curb. On one-way streets, drive toward the road edge nearest you.

When leaving an alley, driveway, or parking lot to enter a roadway, you must stop before driving onto a sidewalk or sidewalk area. Pedestrians and existing traffic have the right-of-way.

If your wheels drop off the roadway or pavement edge, do not attempt to turn back onto the roadway immediately. Instead, reduce your speed, check traffic, and gradually turn back onto the roadway when it is safe to do so.

This sign warns that two lanes of traffic going the same direction will soon merge into one lane.
