Drivers may not enter an intersection unless they can get through it without having to stop. In heavy traffic, wait until the vehicles ahead of you clear an intersection before you proceed so that you are not blocking the intersection when the light for cross traffic turns green.

Before turning or changing lanes, turn your head and glance over your shoulder in the direction of your move to see if your blind spot is clear. Never rely on your mirrors alone.

Yellow lane markings indicate a separation of lanes where traffic is traveling in opposite directions. When you see double solid yellow lane markings, passing is prohibited from both directions.

If an emergency vehicle using its lights or siren approaches while you are driving on a one-way street, you must drive toward the nearest roadside and stop.

When passing a bicyclist, slow down and give them as much space as you can. Bicyclists have much less protection than drivers of motor vehicles and they should not be crowded. Passing a bicycle too quickly can shift the bicyclist off-course.

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.

Crashes often occur when one driver does not see another vehicle or when a driver does something unexpected. Communicate with other drivers on the road to help prevent traffic crashes.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that drivers turning left at a green light must yield to oncoming traffic and may complete the turn when it is safe to do so.

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

When stopped for a traffic violation or at an equipment check, the driver is responsible for producing their license, proof of registration, and proof of insurance. Drivers are required to have all three of these documents in a vehicle when it is being driven.

A round sign means you are approaching a railroad crossing. This sign is posted a few hundred feet in front of the tracks and tells drivers to slow down, look, listen, and prepare to stop.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

Drivers crossing a sidewalk entering or exiting a driveway, alley, or parking lot must yield to pedestrians. It is illegal to drive on a sidewalk, except to cross it.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that there is an upcoming stop sign and that they should prepare to come to a complete stop before proceeding.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

"Reduced speed" signs inform drivers that they must reduce their speeds. If a new speed limit is posted on one of these signs, the new speed limit begins at the sign.

“HOV” stands for “High Occupancy Vehicles.” HOV lanes are reserved for vehicles with more than one occupant. Signs indicate how many people must be in the vehicle, as well as the days and hours during which the restriction applies.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. There may be an upcoming change in traffic direction, a steep downgrade, or another potentially hazardous situation that requires action on the part of the driver.

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.

It is estimated that drivers make 200 decisions for every mile traveled, making it vital that drivers focus their full attention on the task of driving. Performing any additional task can create a dangerous distraction.

A regulatory sign displaying a red circle with a red slash through the middle indicates that a specific action is prohibited. U-turns are not permitted where this sign is posted.

Lane use control signals are used when the direction of the flow of traffic in a specific lane changes throughout the day. They are used to show which lanes of traffic are open and closed, as well as to show if toll booths are open or closed. Never drive in a lane marked with a red X.

If you notice that the road ahead is covered by heavy smoke, reduce your speed immediately, drive as far as possible to the right, and stop off the roadway. Only then should you determine if it is safe for you to continue. Remember that certain kinds of smoke can irritate your eyes and lungs or even kill you.

Always use the proper turn signal when changing lanes, pulling into or out of a parking space, or pulling into traffic from an alley or parking area. Communicate with other drivers on the road to help prevent accidents.

If you are in a lane corresponding to a signal displaying a green arrow, you may proceed in the direction of the arrow when the way is clear. This is true whether the arrow is displayed alone or together with another signal.
