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.

You must yield the right-of-way to any emergency vehicle that is using its siren and lights. Drive to the right edge of the road and stop until the emergency vehicle has passed. If you are within an intersection, drive through the intersection first and then stop.

This sign alerts you to the possibility of traffic merging into the main stream of travel. After checking to your side and rear, you should move into another lane, if possible, to allow merging motorists a clear path.

Warning signs are usually yellow with black markings. This sign indicates that there could be traffic merging from the right, so drivers should prepare to allow traffic to safely merge.

Drivers must always yield the right-of-way to pedestrians in the roadway, even if there is not a marked crosswalk.

When approaching a T intersection while traveling on the street ending at the intersection, you must stop and yield the right-of-way to cross traffic. Only proceed when it is safe to do so.

Pedestrian crosswalks are often shown by white, solid lines to emphasize pedestrian crossing points. Crosswalks may have additional lines between the white, solid lines or in place of the parallel lines. However, crosswalks may also be unmarked.

When entering any roadway, you must be aware of traffic conditions. Use your side mirror and look over your shoulder to help you see and anticipate traffic when entering a freeway.

This sign prohibits drivers from making a U-turn. You cannot turn around to go in the opposite direction at an intersection where this sign is posted.

If a vehicle merges in front of you too closely, take your foot off of the accelerator. This will create space between you and the vehicle ahead without requiring you to slam on your brakes or swerve into another lane.

This sign indicates that a stop sign is ahead.

You must use your headlights at any time when conditions prevent you from seeing other vehicles and when it may be difficult for other drivers to see you. Always use your low beam headlights if weather conditions require you to use your windshield wipers.

When entering and driving through a work zone, slow down and be prepared to stop. Obey posted speed limits and be alert to conditions around you. Workers could be present.

If you are already within an intersection when the traffic light turns yellow, you should clear the intersection as quickly as possible.

If an oncoming driver fails to dim their high beams, you should avoid looking directly at the headlights. Instead, look toward the right edge of your lane and watch the oncoming vehicle out of the corner of your eye.

This sign warns a driver of a change in direction or a narrowing of the road. A driver may find several of these signs on the outside of a sharp curve or on approaches to a narrow bridge.

Always be aware of what is happening around your vehicle. Constantly observing your surroundings to the front, sides, and rear of your vehicle will help you see problems that may require you to change speed or roadway position.

After coming to a complete stop, you may turn left at a red light only if you are traveling on a one-way street and turning onto another one-way street. Only make the turn if there are no posted signs prohibiting such a turn.

When a vehicle makes a turn, the rear wheels follow a shorter path than the front wheels. The longer the vehicle, the bigger the difference between the paths of the front and rear wheels. Therefore, long trucks often have to swing wide to complete a right turn.

The flashing overhead lights and stop arm on a school bus will be activated when the bus is stopped to load or unload students. If approaching a bus using these signals, you may not proceed until the red lights have stopped flashing and the stop arm has been retracted. Never pass a school bus that is dropping off or picking up students.

An octagonal sign always means stop. When approaching a stop sign, you must come to a complete stop at the marked stop line and proceed only when it is safe to do so. If there is no stop line, stop before the crosswalk. If there is no crosswalk, stop before the intersection at a point from which you can see any oncoming traffic.

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.

As you enter a work zone, signs and message boards will warn you of workers, slow-moving equipment, and/or closed lanes ahead. You should reduce your speed and be prepared to slow down or stop.

Drivers of trucks, buses, vans, or any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

Legal medications, both prescription and over-the-counter, can impair your ability to drive. They can be particularly dangerous when used in combination with alcohol.

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.

Because they are larger, trucks take longer to stop than cars traveling at the same speed. Other drivers should not pull in front of a truck and then slow down or stop.

To avoid contributing to chronic traffic congestion, you should not "rubberneck." That is, you should not slow down to look at out-of-the-ordinary things.

Whenever you want to change lanes or enter traffic, you must be sure that there are no vehicles in your way in the lane you want to enter. Always check for traffic to the side of and behind your vehicle before you change lanes.

Blind or partially blind pedestrians may carry a white cane or use the assistance of a guide dog. You must yield the right-of-way to a pedestrian with a guide dog or a white cane.
