If you become tired while driving, it is best to stop to rest or change drivers. Being tired dulls your mind and slows down your reactions, making driving hazardous.

When approaching an intersection with a stop sign, you must come to a complete stop before entering the crosswalk. The crosswalk may be marked or unmarked.

There are a number of locations where it is unlawful for drivers to pass. Passing is prohibited within 100 feet of a railroad crossing, within 100 feet of an intersection, and within any other designated no passing zone.

Yellow lines separate traffic moving in opposite directions. Dashed lines on the pavement indicate that passing is permitted when safe.

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.

Approximately one-third of all motorcycle crashes involve a second motor vehicle. Many motorcycle accidents are caused by the driver of a passenger vehicle turning left in front of an oncoming motorcycle instead of properly yielding the right-of-way.

If you start to feel tired while driving, drive to the first available rest stop or service area to take a break, nap, stretch, or change drivers. You should not rely on caffeine pills or energy drinks, as these are not a replacement for rest and may make your driving even more dangerous.

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.

When following a motorcyclist, allow for at least a three- to four-second following distance. Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist should fall, you need extra distance to avoid the rider. The chances of a fall are greatest on wet and icy roads, gravel roads, and metal surfaces such as bridges, gratings, and streetcar or railroad tracks.

You may not know what is on the other side of a hill or just around a curve, even if you have driven the road many times. If a vehicle is stalled just out of sight on the roadway, you must be able to stop. Whenever you come to a hill or curve, adjust your speed so you can stop if necessary.

Warning signs are used to warn drivers about upcoming hazardous conditions and are usually yellow with black markings. This sign warns drivers that the road ahead curves to the right and then to the left.

Before passing, you must make sure the passing lane is clear and give the proper turn signal to show you are going to change lanes.

This sign indicates that you are approaching a railroad crossing. You must look, listen, slow down, and prepare to stop. Wait for any trains to pass before you proceed.

If an emergency vehicle with flashing lights is traveling in the area where you are driving, you must make every effort to give them a clear path of travel. If it is safe to do so, pull your vehicle to the side of the road to give the emergency vehicle an open pathway.

This sign prohibits U-turns. Do not make a U-turn where this sign is posted.

It is generally unlawful to pass a school bus that has its stop lights on and stop arm extended. However, you do not need to stop when the bus is on the opposite side of a roadway divided by a median.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign indicates that parking is not permitted.

Pavement can become very slippery within the first 10 to 15 minutes of a rainstorm because the rain causes oil in the asphalt to rise to the surface of the road. This problem becomes even worse in hot weather. The heat combined with the water causes more oil to rise to the road surface.

When passing is permitted, look for both headlights of the passed vehicle in your rearview mirror. Only then may you safely return to your original lane.

Slow down and be prepared to stop whenever you see pedestrians walking on or crossing the roadway. Be particularly careful where children are present. Always yield the right-of-way to a pedestrian crossing in a crosswalk.

You should never change lanes within an intersection. Before changing lanes, always look over your shoulder to check your blind spot. Be alert to other drivers moving into the same lane.

Only the passage of time can remove alcohol and its impairing effects from the body.

Some warning signs have a fluorescent yellow-green background. These signs warn of upcoming conditions, including roads with curves and sharp turns.
