Round signs warn drivers of an upcoming railroad crossing area. Drivers should use extra caution when approaching a railroad crossing.

When you hear the siren of an emergency vehicle, you must pull over to the curb or side of the road and stop.

This sign indicates that right turns are prohibited.

Telltale signs of drunk driving include speeding, weaving, driving more slowly than the normal traffic flow, making jerking motions, and making quick and sudden stops.

The ability to drive safely is dependent on the driver being in good physical condition. Driving can be impaired by alcohol, legal and illegal drugs, and being drowsy.

Never stop on railroad tracks. If your car stalls on the tracks and you cannot restart it, get out and try to push the car off the tracks. If you cannot push the car off the tracks, get help. Do not begin to cross railroad tracks unless your car can entirely clear the tracks.

Even the smallest amount of alcohol will reduce your concentration, perception, judgment and memory, and your driving skills will suffer. No one can drink and drive safely.

At intersections that are controlled by signs or signals and at intersections that are uncontrolled, the driver on the left must yield the right-of-way to the driver on the right when two vehicles arrive to the intersection at the same time.

Unless a posted sign prohibits it, you may turn right or left at a steady green light. When turning, you must yield to other vehicles and pedestrians within the intersection.

When you wish to change lanes or make a turn, signal with arm signals or mechanical turn signals to inform other motorists of your intention. Signals should be activated at least 100 feet before you make a turn. If you are using mechanical signals, continue signaling until you have completed the turn or lane change.

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.

As an increasing number of drivers populate the roadways, road rage becomes more prevalent. To help prevent road rage, a driver should use proper turn signals, obey posted speed limits, and allow plenty of travel time.

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

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

This signs warns that a four-way intersection is ahead.

If you are stopped by law enforcement, you should park your vehicle as far to the right side of the road as possible. If available, park on the right shoulder or park on a nearby well-lighted side street or parking lot away from high-volume traffic.

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

If you pass on the right, do so only when conditions permit you to do so legally and safely. You should never pass another vehicle on the right by leaving the main paved road.

Any eight-sided sign is a stop sign. At an intersection with a stop sign, you must stop completely and check for pedestrians and cross traffic in the intersection. Wait for the intersection to clear before proceeding.

If a green arrow is shown with a red light, you can only drive in the direction of the arrow and only if the intersection is clear.

If you come to a roadway that is flooded, turn around and find another way to go. Do not attempt to drive through the water. It is impossible to determine the depth or current and your vehicle could become submerged or swept away.

Many crashes are caused by drivers who are driving too fast for conditions. Always drive within the legal speed limits and decrease your speed any time conditions are less than perfect.

When passing another vehicle on a two-lane roadway, you must return to the right side of the roadway when there is enough room between you and the vehicle you have passed.

Don’t cut in too quickly after passing a large vehicle. Look for the entire front of the vehicle in your rearview mirror before changing lanes and do not slow down. Truck and bus drivers need nearly two times more room to stop than other drivers.

For drivers age 21 or older, it is illegal to operate a motor vehicle with a blood alcohol concentration (BAC) of 0.08 percent or higher. Driving while under the influence of alcohol is not only illegal, but dangerous.

The distance required to stop your vehicle depends on perception time, reaction distance, and braking distance. This changes with speed and road conditions.

When stopped at an intersection, you should first look to your left, as vehicles coming from the left are closer to you than vehicles coming from the right. Look to your right, then look to your left again, in case there are any vehicles coming from that direction that you did not see at first glance.

This sign warns that pavement is slippery when wet. In wet conditions, you should reduce your speed, avoid braking or changing direction suddenly, and increase the distance between your vehicle and the one ahead.

You should not park within 20 feet of a crosswalk. An improperly parked vehicle may cause a crash.

A solid yellow arrow has the same meaning as a yellow traffic light. When approaching a solid yellow arrow, you must reduce your speed and prepare for a red light.
