Stop before the stop line or crosswalk at any intersection that is controlled by a stop sign. If there is a stop sign but no stop line or crosswalk, stop before entering the intersection and proceed when it is safe to do so.

White lines are used to separate traffic moving in the same direction. Dashed lines indicate that drivers directly next to the line are permitted to pass when it is safe to do so.

When entering a roadway from a driveway or private road, you must yield the right-of-way to pedestrians and traffic on the roadway.

The exhaust system helps remove toxic gases, reduce the noise, and cool the hot gases coming from a running engine. Fumes from a leaky exhaust system can cause death in a very short time. They can also make you drowsy while driving.

If you follow too closely and the vehicle in front of you slows or stops suddenly, you may not have enough time to avoid a collision.

A speed limit sign shows the maximum legal driving speed for the stretch of highway where it is posted. Driving safely may require you to travel more slowly than the posted limit. When conditions are less than ideal, drivers should slow down.

If another driver is threatening you or intentionally driving dangerously around you, remain calm and try to put as much distance between the two of you as possible. Slow down and let them pass. Do not make eye contact and do not make obscene gestures.

Highway markings provide information for drivers. Markings help drivers correctly position their vehicles on roadways, inform drivers of safe passing zones, and warn drivers about upcoming conditions.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign means that right turns are prohibited.

This sign indicates that left turns are prohibited.

This sign indicates that a divided highway begins ahead. The road splits into two one-way roadways separated by a median or divider. You must keep to the right.

Drivers must always yield to pedestrians in the street, even if they are crossing against a red light or are otherwise being careless.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

When driving on a two-lane roadway or undivided highway, you must yield to an emergency vehicle using its lights and/or siren, regardless of the direction from which it is approaching. Immediately drive as near as possible to the right side of the road and stop, taking care not to stop within an intersection.

A steady red traffic light indicates that drivers must come to a complete stop. Driving through a red light is against the law and is extremely dangerous. Drivers may turn right on a steady red light if there is no sign prohibiting a turn on red.

When on a roadway with two or more lanes, you should make room for entering vehicles. If there is no one driving next to you, move over one lane.

If you experience a tire blowout, take your foot off the gas pedal and do not immediately apply the brakes. Gradually slow down before gently applying the brakes and pulling off the side of the road.

Regulatory signs require drivers to obey an indicated instruction. Failure to comply is subject to penalty.

You must pull over to the right edge of the road and stop for an emergency vehicle with flashing lights, regardless of whether it is approaching you from behind or from the opposite direction.

Double solid yellow lines in the center of the road mean that passing is not allowed from either direction. You may not cross the lines unless you are making a left turn or passing pedestrians, bicyclists, and riders of scooters or skateboards when the opposite lane is clear and you can pass safely.

Drinking coffee will not reduce your blood alcohol concentration (BAC). While it may help you to stay awake, it cannot change your BAC or make you sober.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to an upcoming traffic signal. They should be prepared to respond to a yellow light, red light, and/or cross traffic.

Passing is not permitted within 100 feet of a bridge, viaduct, or tunnel. Be sure to only pass where other drivers can clearly see your vehicle.

To check your blind spot before changing lanes, you should look over your shoulder in the direction that you plan to move.

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.

Motorcycles are entitled to the width of a full lane. Be sure your vehicle is entirely in the left lane before attempting to pass a motorcycle on the left.

A steady yellow traffic light indicates that the light will soon change to red. You should be prepared to stop for the red light, if it is safe to do so.

Only the passage of time will allow a person to overcome the influence of alcohol.

You must always signal before turning or changing lanes. You should keep your wheels straight while waiting to make a left turn. If another vehicle hits you from behind, this ensures that you will not be pushed into oncoming traffic.

As an increasing number of drivers populate the roadways, road rage becomes more prevalent. To help prevent road rage, a driver should use proper turn signals, obey posted speed limits, and allow plenty of travel time.

In general, vehicles at a four-way stop should proceed in the order that they arrive. However, if two vehicles arrive to the intersection at the same time, the vehicle on the left must yield the right-of-way to the vehicle on the right.

Before changing lanes, you should activate your turn signal in the appropriate direction and check your rearview and side mirrors. Look over your shoulder in the direction you plan to move in order to check your blind spot and check the far lane to be sure no one else is trying to enter the same lane as you. Change lanes when you are sure it is safe to do so.

The distance required to stop your vehicle depends on perception time, reaction distance, and braking distance. This changes with speed and road conditions.

This sign indicates that the shoulder is lower than the road in the area ahead. If you drift off of the roadway and one wheel drops onto a low shoulder, do not slam on the brakes or steer sharply to try to get back onto the roadway. This could easily cause you to lose control of your vehicle.

You should pass a bicyclist the same way you would pass any other vehicle, but not so fast or close to them that you throw debris in their face or blow them around with the draft of air from your vehicle. Allow at least 3 feet of space between your side mirror and the bicyclist, or at least 5 feet on higher speed roads or when there is a group of bicyclists. Honking unnecessarily may startle riders and make them more likely to crash.

When heavy rain reduces visibility, reduce your speed. Turn on your headlights so other drivers can see your vehicle. If the rain is so heavy that you are unable to see clearly, drive onto the shoulder and stop until the rain lets up.

At night, your field of vision is reduced. To make sure you are able to react to hazards on the roadway, always use appropriate headlights. Drive slowly enough that you are able to stop within the distance that you can see ahead.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

When you are approached by an emergency vehicle that is using its lights, sirens, and/or other warning devices, you must immediately drive to the right side of the road and stop.

In many collisions with motorcycles, bicycles, and pedestrians, drivers reported that they were looking but still did not see the smaller vehicle or pedestrian. These can be more difficult to spot in traffic than passenger vehicles because they are smaller, may move faster, and have less noticeable lighting. To prevent collisions with these smaller and less protected road users, drivers should always be alert to the presence of motorcycles, bikes, and pedestrians.
