A round yellow sign indicates that there is a railroad crossing ahead.

Instructions given by police officers directing traffic always override posted traffic signals and signs. Follow the officer's instructions.

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.

Warning signs are usually yellow with black markings. This sign indicates that the road ahead will turn sharply to the right and then sharply to the left.

You must yield to pedestrians at all times. If the pedestrians are jaywalking or crossing the street where they should not be, you must still stop for them.

If there is danger, you may need to sound a sharp blast on your horn. Do this when a child or any other pedestrian is about to enter into the street in front of your moving vehicle.

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.

When approaching this sign, you must yield the right-of-way. Slow down and let vehicles and pedestrians crossing your path pass before you proceed. If necessary, stop before going ahead.

Downward-facing triangular signs mean drivers must yield. When approaching a yield sign, slow down to a speed that is reasonable for existing conditions and stop if necessary. If you must stop, do so at a marked stop line, if it exists.

Because they are larger, trucks take longer to stop than cars traveling at the same speed. Other drivers should not pull in front of a truck and then slow down or stop.

A double yellow centerline means that it is prohibited for traffic from either direction to cross the centerline to pass.

When changing lanes, look over your shoulder in the direction you plan to move. Check for obstructions near the rear corners of your vehicle. These areas are called “blind spots” because you cannot see them by using your mirrors.

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.

If a vehicle merges in front of you too closely, take your foot off of the accelerator. This will create space between you and the vehicle ahead without requiring you to slam on your brakes or swerve into another lane.

Warning signs provide notice to road users of a situation that might not be readily apparent and are usually yellow with black markings. This sign warns drivers to be careful when driving under wet conditions as the pavement will become slippery and more difficult to navigate safely.

You must yield the right-of-way to any emergency vehicle that is using its siren and lights. Drive to the right edge of the road and stop until the emergency vehicle has passed. If you are within an intersection, drive through the intersection first and then stop.

Pedestrians using guide dogs or white canes (with or without a red tip) must be given the right-of-way at all times.

Yellow lines mark the center of a road used for two-way traffic. A solid yellow centerline indicates that drivers may not cross the line to pass. A broken yellow centerline indicates that drivers may cross the line to pass, but only if passing would not interfere with traffic.

A turnabout is a legal way to turn a vehicle around. When you are considering using a turnabout, you should first make sure your car can be seen for at least 500 feet in either direction.

If your vehicle is hit from the rear while you are in forward motion, your body will be thrown backward. Press yourself against the back of your seat and put your head against the head restraint to prevent whiplash. Maintain a firm grip on the steering wheel and be ready to apply your brakes to avoid being pushed into another vehicle.

When driving under snowy or icy conditions, you should make speed and directional changes gradually. Never use cruise control when driving on snow or ice because your tires may lose contact with the road and you will lose control of your vehicle.

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.

Warning signs are usually yellow with black markings. This sign warns drivers that the roadway will be slippery when wet and they should reduce their speed accordingly.

When changing lanes, you must be sure that there are no vehicles in the space you want to enter. Check for other vehicles behind and to the side of your vehicle by checking your mirrors and blind spots. Always use the proper turn signal before changing lanes to allow surrounding vehicles time to react to your movements.

You must yield the right-of-way to any emergency vehicle that is using its siren and flashing lights. Do this by driving to the right edge of the road and stopping, taking care not to stop in an intersection. You may move again after the emergency vehicle has passed.

Drivers of trucks, buses, vans, and any vehicles pulling campers or trailers may not be able to see you if you are driving directly behind them. Increase your following distance when driving behind one of these vehicles. Additionally, large vehicles can block your view of the road, so increase your following distance to look around the sides of the vehicle and see the road ahead.

Alcohol and other drugs can negatively effect a number of skills needed for safe driving, including a driver's reaction time, coordination, alertness, and ability to concentrate.

If a tire blows out or suddenly goes flat while you are driving, grip the steering wheel firmly and keep the vehicle aiming straight. Take your foot off the accelerator and do not brake. Allow the vehicle to slow by itself and use the brakes gently, but only if necessary. Pull off the road when it is safe to do so.

Regulatory signs inform drivers of specific laws that must be obeyed. Displayed laws may be about traffic direction, lane use, turning, speed, parking, or special situations. Regulatory signs are commonly white squares or rectangles with black, red, or green letters or symbols.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. If you are making a left turn from a one-way street, this means that you would make the turn from the lane nearest to the left curb.

When parking uphill on a road that has a curb, your wheels should be turned away from the curb. When parking uphill on a street without a curb or when parking downhill, your wheels should be turned toward the curb or edge of the road.

Alcohol is a depressant that dulls your judgment and makes your reflexes unreliable.

After coming to a complete stop, you may turn left at a red light only if you are traveling on a one-way street and turning onto another one-way street. Only make the turn if there are no posted signs prohibiting such a turn.

Backing up is always dangerous because it is hard to see behind your vehicle. Use extra caution when backing up.

A flashing red light at an intersection means drivers are required to come to a complete stop, yield to traffic and pedestrians, and proceed when the way is clear. The same is true at a stop sign.

When turning, you should look to the rear and both sides of your vehicle to ensure it is safe to proceed before making the turn. Adjust your speed to safely complete the turn.

The flashing overhead lights and stop arm on a school bus will be activated when the bus is stopped to load or unload students. If approaching a bus using these signals, you may not proceed until the red lights have stopped flashing and the stop arm has been retracted. Never pass a school bus that is dropping off or picking up students.

This sign warns that two lanes of traffic going the same direction will soon merge into one lane.
