This sign warns of two-way traffic.

Anytime you want to merge with other drivers, you need to find a gap large enough for you to safely enter into the flow of traffic. You should not stop on the entrance ramp to an interstate highway unless there are no gaps into which you may safely merge.

This sign lets you know that your lane is splitting into two separate directions. You may turn left or continue driving straight when in a lane controlled by this sign.

If your vehicle breaks down on a highway, make sure other drivers can see it. Get your vehicle off the road and away from traffic if at all possible and turn on your emergency flashers to show that you are having trouble.

Expect a train on any track, at any time, traveling in either direction. If you need to stop after crossing the tracks, wait until you can completely cross the tracks before proceeding. Make sure your vehicle clears the tracks before you stop.

When approaching a pedestrian who is using a white cane or guide dog while crossing the street, you must stop until the person is well away from your path of travel. Always yield the right-of-way to blind pedestrians.

Where this sign is posted, it is prohibited to make a right turn. It would be unsafe and unlawful to make a right turn at an intersection with this sign.

A distraction when driving is anything that takes your attention away from driving. Driver distractions may occur anytime and anywhere. Distracted driving can cause collisions, resulting in property damage, injury, and death.

Signs with a red circle and diagonal line over a black symbol indicate that the action represented by the symbol is prohibited. In this case, the sign indicates that left turns are prohibited.

State law requires that safety belts are worn even if a vehicle is equipped with airbags. While airbags are good protection against hitting the steering wheel, dashboard, and windshield, they do not protect you if your vehicle is hit from the side or rear or if the vehicle rolls over. An airbag will not keep you behind the wheel in these situations.

Alcohol, in any concentration, is a depressant. It slows all nerve impulses and bodily functions, resulting in a lessening of inhibitions and negatively affecting a consumer's ability to concentrate and stay alert.

Use high beam headlights only when driving in rural areas and when other cars are not nearby. Lower your headlights to their low beam setting when you are following closely behind another driver.

A green arrow means "go." You must turn in the direction the arrow is pointing after you yield to any vehicles, bicycles, or pedestrians who are still in the intersection.

Using a cell phone while driving is dangerous because it occupies the user's eyes, hands, and mind. Even the most skilled drivers increase their risk of being involved in a crash by using a cell phone on the road.

You should always signal when moving your vehicle to the right or left. On an interstate, you should stay in the right lane if you are moving more slowly than the surrounding traffic. It is illegal to back up or make a U-turn on interstate highways, so if you miss your exit, you should proceed to the next exit.

A single broken line indicates that drivers may cross from either lane to change lanes. Dashed yellow lines alongside solid yellow lines indicate that passing is permitted from the lane next to the broken line, but not from the lane next to the solid line. Only change lanes when it is safe to do so.

When parking downhill, turn your front wheels toward the curb or edge of the road. When parking uphill on a road without a curb, turn your wheels toward the edge of the road. When parking uphill on a road with a curb, you must turn your front wheels away from the curb.

When traffic control signals are not working, a driver must always treat the intersection as an all-way stop and come to a complete stop, unless otherwise directed by law enforcement. The driver must then look and yield the right-of-way before entering the intersection.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. Be aware of vehicles that must stop at all railroad crossings, such as school buses and trucks carrying hazardous materials.

Use your right foot for both braking and accelerating. You should apply the brakes gently with increasing pressure so that your vehicle stops gradually and smoothly.

Before beginning a right turn, use the appropriate signal to give surrounding drivers adequate notice of your intentions. Slow down and approach the intersection from the right lane, staying as close as is practical to the right curb or edge of the roadway.

If you want to enter the freeway but do not see a space for your vehicle in traffic, slow down on the ramp to wait for a gap. Do not drive to the end of the ramp and wait for a gap or you will not have enough room to accelerate to the speed of traffic before entering the roadway.

Reduce your speed and be prepared to slow down or stop for highway equipment. Driving carefully through work zones improves safety for drivers, pedestrians, bicyclists, and road workers.

If there are oncoming vehicles to your left and a row of parked vehicles to your right, the best thing to do is to split the difference. Steer a middle course between the oncoming cars and the parked cars.
