Pennant-shaped warning signs like this are only used to indicate a no passing zone.

This sign warns drivers that the divided highway ends ahead.

To avoid becoming fatigued while taking a long trip, stop every two hours for a short break. If you become drowsy, pull off the road and park in a safe place to take a nap, or find a room to stay for the night.

Alcohol reduces your reaction time, reduces your ability to see clearly, changes your judgment of speed and distances, reduces your ability to recover from the glare of headlights, and often reduces your inhibitions and makes you more likely to take risks.

The larger the vehicle, the larger the blind spots. Large trucks and SUVs have spots close to their rears that cannot be seen in their side or rearview mirrors.

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.

A broken yellow line alongside a solid yellow line means that passing is allowed from the lane on the side next to the broken line.

This one-way sign indicates that traffic flows only in the direction of the arrow.

Blind spots are areas around your vehicle that you cannot see by using your mirrors. Check your blind spots by turning your head and glancing over your shoulders.

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.

A flashing yellow light warns of a hazard. Slow down and proceed with caution.

School buses and tank trucks carrying flammable liquids must stop at all railroad tracks before crossing, regardless of the presence of a train. Be prepared to stop at all railroad crossings if following one of these vehicles.

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.

Do not become distracted by looking at passengers, attempting to find something in your vehicle, looking at reading material, sightseeing, or daydreaming while driving. Continue scanning the road, checking your mirrors, and looking at the instrument panel at regular intervals. Developing these safe habits will keep you attentive as a driver.

You must yield the right-of-way to police cars, fire engines, ambulances, or any other emergency vehicles using a siren or air horn and a red or blue flashing light. Follow any instructions given over the emergency vehicles' loudspeakers. Emergency vehicles often follow each other so you should proceed only when you are certain the way is clear.

Before changing lanes, you should always verify that there are no other vehicles in the lane you want to enter by checking your mirrors and looking over your shoulder in the direction you plan to move. You should signal every time you change lanes.

A steady yellow arrow indicates that a red arrow is about to appear. Stop unless you are already within the intersection.

The exhaust system carries exhaust gas out of the vehicle and prevents fumes from entering into the passenger compartment. To prevent carbon monoxide poisoning, keep your exhaust system free of leaks. Replace all defective parts immediately.

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.

Using a cell phone (including a hands-free phone) or any kind of audio device (including a radio or CD player) can be a dangerous distraction and contributes to the risk of a crash.

Keeping a safe following distance will enable you to react to an upcoming problem without the need for a emergency stop, which could cause a driver behind you to crash into the back of your vehicle.

Decrease your speed as you approach an intersection with a yield sign. Prepare to stop and yield the right-of-way to vehicles and pedestrians in the intersection or crossroad. You must come to a full stop at a yield sign if traffic conditions require it.

Your physical condition has an important bearing on your ability to drive safely. Drivers should be aware of their physical limitations and only drive if it is safe to do so.

After finding a parking space, checking traffic, and signaling, you should stop parallel to the vehicle directly ahead of your desired parking space before turning your wheel to park.

When using a freeway exit ramp, do not slow down until you move onto the exit ramp.
