A triangular red and white yield sign means that you must decrease speed as you approach an intersection and yield the right-of-way to any vehicles or pedestrians in the intersection. You must be prepared to stop if conditions require it.

Traffic lanes moving in the same direction are separated by broken white lines. You may cross over dashed lines to pass, if it is safe to do so.

If you experience a tire blowout, do not immediately apply the brakes. Grip the steering wheel firmly and steer to remain in your traffic lane. Reduce your speed gradually by releasing the accelerator and staying off the brakes. Once you are moving very slowly, apply the brakes lightly and pull off the road into a safe area.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers about an upcoming winding road.

Diamond-shaped signs are used to warn drivers of special conditions or hazards ahead. They are typically yellow or orange in color.

The only way to sober up after drinking alcohol is to allow time for your body to eliminate the alcohol in your system. Nothing you can do, including eating and drinking, can accelerate this process.

You must yield the right-of-way to a police vehicle, fire engine, ambulance, or other emergency vehicle using a siren or air horn and red or blue flashing lights. Pull over to the right edge of the road, or as near to the right side as possible, when you see or hear an emergency vehicle approaching from any direction on an undivided highway.

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.

Most signs in work areas are orange and diamond-shaped, although some signs are rectangular. These signs and traffic control devices are commonly reflective to better attract your attention at night.

When driving an unfamiliar vehicle, take a few minutes before driving to familiarize yourself with the location and operation of the turn signals, hazard warning signals, headlights and beam selector, windshield wipers and washers, brakes, gear selector, and horn. Any defects should be corrected before the vehicle is driven.

As you prepare to make a right turn, you should get as far to the right side of the road as possible. Do not cut across lanes of traffic to perform any turn.

When entering the interstate on a short entrance ramp where there is no acceleration lane, speed up only after you have identified a gap in traffic. In general, you should be stopped while waiting for a gap to appear.

Anything that causes you to take your attention away from driving, take your eyes off the road, and/or take your hands off the wheel is a distraction.

When a school bus is stopped with its red lights flashing and stop arm out, other drivers are required to stop. This law applies to drivers traveling on both public and private roads.

At a stop sign, you must come to a complete stop at the stop line, if there is one. If there is no stop line, you must make a complete stop before entering the crosswalk. If there is no crosswalk, you must stop before entering the intersection.

This sign indicates that there is a traffic signal ahead.

Use your low beams when driving in fog, snow, rain, or mist. Light from high beams will reflect off of precipitation, causing a glare and making it even more difficult to see. Some vehicles are equipped with fog lights that should be used in addition to low beam headlights.

If your vehicle begins to skid, stay off the brakes. Continue to correct your steering until the vehicle is back under your control and moving safely down the road.

This sign warns that a road has one-way traffic and you must not enter from your current direction.

You should avoid making any sudden changes in speed or direction when driving on a slippery surface. Reduce your speed on slippery roads and do not use cruise control.

Railroad crossings are always dangerous. Drivers should look and listen for an approaching train coming from either direction before proceeding across the tracks. Watch for signals indicating an approaching train and never proceed until you are certain it is safe to do so.

When driving to an unfamiliar area, plan your trip in advance. Don’t start with only a hazy idea of where you are going. If your destination is in an unfamiliar area, check the location on a map before you start to drive.

Alcohol slows your reflexes and reaction time, reduces your ability to see clearly, and makes you less alert. As the amount of alcohol in your body increases, your judgment worsens and your driving skills decrease. You will have trouble judging distances, speeds, and the movement of other vehicles.

Pentagonal signs indicate that you are in or are approaching a school zone and/or school crossing. Be aware of children when driving near a school zone and follow posted speed limits.

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

When traffic permits, you should make room to allow vehicles to merge into your lane.

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.

If you follow too closely and the vehicle in front of you slows or stops suddenly, you may not have enough time to avoid a collision.

Yield to pedestrians and cars that may be caught in an intersection when you have a green light. Be careful around pedestrians under every circumstance.

Low beam headlights should be used when driving in rainy or foggy weather. Even if they do little to help you see, low beams will make it easier for others to see you.
