Because it is dark, drivers cannot see as well at night as they can during the day. From one half hour after sunset until one half hour before sunrise, or at any other time when persons or vehicles are not visible for 500 feet, drivers must use their headlights.

This sign indicates that the right lane on a multilane roadway ends ahead. Traffic in the right lane must merge left.

Railroad crossings are always dangerous. Drivers should always look and listen for trains approaching from either direction on all railroad tracks. Always follow the directions indicated by signs, signals, and flaggers. Never proceed past a railroad crossing until you are certain it is safe to do so.

If you approach an emergency vehicle, tow truck, or roadside assistance vehicle that is stopped with its lights flashing, you must change lanes to allow the vehicle extra space. If there is only one lane moving in your direction, or if changing lanes would be unsafe, you must slow down to a speed below the posted speed limit and give the stationary vehicle as much room as possible. Always slow down and be prepared to stop when you approach an emergency scene.

Traffic signals are placed at intersections to keep traffic moving and to help prevent crashes. Drivers, pedestrians, and cyclists must obey these signals, except in instances when an officer is directing traffic.

Lane usage for the motorcyclist is critical. Motorcycles are entitled to the same full lane width as all other vehicles.

Yellow lines are used in the center of the road to separate lanes of traffic moving in opposite directions.

If you hear the siren or see the flashing lights of an emergency vehicle, you must slow down, provide a clear path for the vehicle, and stop. Don't try to outdrive the emergency vehicle.

Blind spots are areas that a driver cannot see without moving their head. They can be located to the sides of and behind a vehicle.

At night, visibility is reduced. Take steps to make driving in the dark more safe for you and the other drivers on the road.

Other cars and motorcycles are often hidden in a vehicle’s blind spot, so be sure to glance over your shoulder before you begin a lane change. Begin signaling 100 feet before changing lanes or turning in a residential area. Signal five seconds in advance when changing lanes on a freeway.

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.

If your wheels drop off the pavement and onto a low shoulder, you should reduce your speed without braking and very carefully turn back onto the pavement. Be aware of any nearby traffic when re-entering the road.

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

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.

Loose objects fly through a vehicle in a crash and can cause serious injury to a vehicle's occupants. Do not place heavy or sharp objects on the dashboard or rear window shelf of your vehicle.

A flashing yellow traffic light means drivers should slow down and proceed with caution.

At an intersection of two similar roads without a traffic control device, a driver must yield to a vehicle approaching from the right.

Signs providing information about destinations are green with white letters or symbols.

Lap belts should fit snugly across your hip bones and the lower part of your abdomen. Shoulder belts should sit comfortably so that you can insert your fist between the belt and your chest.

It is important to stay alert on highways and be ready to react to unexpected hazards. To avoid "highway hypnosis," you should avoid looking at any one thing for more than a few seconds.

On a traffic signal arranged vertically, red is always on top and green on the bottom. When arranged horizontally, red is always on the left and green on the right.

"No zones" are the large blind spots around trucks and other large vehicles. Drivers of smaller vehicles should avoid lingering in "No zones."

When approaching railroad tracks, you should look, listen, slow down, and be prepared to stop for trains or other vehicles that may be using the rails.

This sign indicates that the overpass ahead has a low clearance. You should not proceed if your vehicle is taller than the height shown on the sign (in this case, 13 feet 6 inches).

This sign indicates that there is a sharp right turn ahead.

This sign indicates a low ground railroad crossing. Where this sign is present, railroad tracks cross the road at a steep slope and the bottom of low vehicles may drag or get caught on the tracks.

Construction, maintenance, and emergency operations signs are generally orange with black symbols.

A flashing yellow traffic light at an intersection indicates that drivers must slow down, proceed with caution, and be prepared to stop.

Drivers may not park within 20 feet of a crosswalk at an intersection. Park where it is legal to do so and where drivers coming from both directions can clearly see your vehicle.

If you miss your turn or exit, do not back up, but go on to the next turn or exit where you can safely turn around. It is illegal to back up on a shoulder or a freeway.

Be prepared to reduce your speed and use caution when directed to do so by a sign, crossing guard, or law enforcement officer. Always drive with extra caution in a school zone.

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.

Use your right turn signal before returning to the right lane after overtaking a vehicle. Return to your previous lane when you can see the entire passed vehicle in your rearview mirror.

If you are involved in an accident, you must stop at or near the scene. Move your vehicle out of the way of traffic, if possible. Do not stand or walk in traffic lanes as you could be struck by another vehicle. Turn off the ignitions of wrecked vehicles.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers that they are approaching a T intersection and should prepare to turn either right or left.

When stopped behind another vehicle, stay back at a distance that allows you to see the ground under the vehicle’s rear wheels. This will allow you to safely move around the vehicle if needed. A space cushion will also help if you are parked on a hill and the car in front of you begins to roll backward after the driver releases the brake pedal.

A "No stopping" sign means you can only stop to obey a traffic signal, to obey a police officer, or to prevent a conflict with another vehicle.

This sign warns that the overpass ahead has a low clearance. Do not proceed if your vehicle is taller than the height indicated (in this case, 13 feet, 6 inches).

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.
