A steady green light means you may drive through the intersection if the road is clear. You may also turn right or left on a steady green light unless a sign prohibits the turn. When turning, you must yield to other vehicles and pedestrians within the intersection.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign tells drivers that they are approaching a school zone and that they should slow down and watch for children.

White lines separate lanes of traffic that are moving in the same direction. Dashed white lines may be crossed to pass or change lanes, if it is safe to do so.

The distance that a vehicle needs to stop depends on the motorist's reaction time, weather and visibility conditions, the vehicle's weight, the conditions of the vehicle's brakes, the condition and type of the vehicle's tires, roadway conditions, and speed.

You should always reduce your speed and use extra caution when children are in the vicinity. They may fail to understand the danger and may run out in front of you without looking.

You must stop at a railroad crossing when directed to do so by a flagger, stop sign, or warning devices, such as gates or flashing lights. Not all railroad crossings are equipped with such devices. It is against the law to drive around lowered railroad crossing gates.

Using a cell phone (including a hands-free phone) or any kind of audio device (including a radio or CD player) can be a dangerous distraction and contributes to the risk of a crash.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

The faster you drive, the smaller your field of vision becomes. As your speed increases and your field of vision decreases, you must be extra alert to potential hazards.

You must yield the right-of-way to any emergency vehicle that is using its siren or flashing lights.

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.

Motorcycles are smaller and harder to see than cars. Because of their size, they are easily hidden in a car’s blind spot. It may be difficult to judge your distance to a motorcycle and difficult to tell how fast a motorcycle is moving, so always be alert and extra cautious when near a motorcyclist.

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

If you are turning left from a two-way street onto a one-way street, you should complete the turn into the lane closest to the lane you have just left.

If a steady yellow light appears when you are already within an intersection, you should continue through the intersection carefully.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign alerts drivers to potential traffic merging from the right. Drivers should prepare to allow the traffic to merge safely.

This sign indicates that right turns are prohibited.

This sign indicates that a T intersection is ahead.

To prevent hydroplaning, you should ensure that the tires on your vehicle have good tread depth and are inflated to the proper pressure. Reduce the speed of your vehicle when driving in the rain. Hydroplaning occurs most frequently at higher speeds.

A sign with a red circle and slash over a symbol indicates that the action represented by the symbol (in this example, a right turn) is not allowed.

Chevron signs like this indicate that the road curves sharply in the direction indicated by the chevron (in this case, to the left). There may be several chevron signs placed throughout a curve.

Distracted driving is extremely risky behavior that puts not only you and your passengers in danger, but also endangers pedestrians, bicyclists, and other motorists sharing the road. Focused attention on driving helps to prevent crashes.

Eight-sided traffic signs warn drivers that they must stop and yield the appropriate right-of-way at an intersection. Drivers may proceed when it is safe to do so.
