To prevent drowsiness on long trips, you should schedule regular stops. Give yourself time to rest and stretch, even if you are not feeling tired.

Be very cautious any time you encounter an animal on the roadway. Pass the animal slowly to avoid startling or frightening it.

If you are being tailgated by another driver and there is a right lane, move over to the right. If there is no right lane, wait until the road ahead is clear and then reduce your speed slowly. This will encourage the tailgater to drive around you. Never slow down abruptly as this will only increase the risk of your vehicle being hit from behind.

"Reduced speed" signs inform drivers that they must reduce their speeds. If a new speed limit is posted on one of these signs, the new speed limit begins at the sign.

When approaching a flashing red signal, you must stop and yield to all traffic that does not have to stop.

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.

Yellow lines separate traffic moving in opposite directions. A single dashed yellow line in the center of a road indicates that vehicles traveling in both directions are permitted to pass. Drivers may only begin a pass if they will not interfere with any oncoming traffic.

This sign warns that especially slippery conditions exist when the road is wet.

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

When driving near a blind pedestrian who is carrying a white cane or walking with a guide dog, you must slow down, yield the right-of-way, and then proceed with caution. Be prepared to stop your vehicle in order to prevent injury or danger to the pedestrian.

Motorcycles are entitled to the width of a full lane. Be sure your vehicle is entirely in the left lane before attempting to pass a motorcycle on the left.

Tractor-trailers take longer distances to stop than smaller cars traveling at the same speed. A fully loaded tractor-trailer may take almost 400 feet to come to a complete stop when driving at 55 mph.

You must not drive at a speed that is faster than is reasonable and prudent. You must drive at a speed that is appropriate for the area where you are driving, the type and condition of surrounding traffic, the presence of pedestrians, the weather, the quality of the road, and light conditions. You must drive within legal speed limits.

This sign means that you are approaching an upcoming intersection. Watch carefully for cross traffic.

Because it is dark, drivers cannot see as well at night as they can during the day. From one half hour after sunset until one half hour before sunrise, or at any other time when persons or vehicles are not visible for 500 feet, drivers must use their headlights.

A solid yellow line next to your lane means that passing is not permitted from your direction.

This sign indicates a merge ahead. It warns that two lanes of traffic moving in the same direction are about to become one.

When exiting a highway, you should get into the exit lane well in advance. Do not begin to slow down until after you have moved into the exit lane.

Warning signs, which tell you about conditions on or near the road ahead, are usually diamond-shaped with black symbols or words on a yellow background.

You may not be able to drive well if you are worried, excited, crying, angry, or depressed. Emotions can distract you from your driving because your mind is focused on something else. Take time to calm down and get focused before driving.

As a general rule, broken traffic lines may be crossed but solid lines may not. Solid yellow lines may be crossed only when the driver is making a turn.

Drowsiness can make people drive so poorly that they appear to be drunk. Opening a window, turning on the radio, or drinking coffee is not enough to make a drowsy driver alert to roadway hazards.

You must always stop before crossing railroad tracks if flashing red lights are activated, a crossing gate is lowered, a stop sign is posted, a flagger signals you to stop, or a train is visible or so close to the crossing that it would be hazardous to continue driving. If you are unsure if a train is too close for you to safely cross the tracks, stop. Never race a train.

Alcohol is a depressant drug that slows the activity of the brain and reduces the skills that you need for safe driving. Drinking alcohol results in slowed reaction time and impaired judgment.

A flashing yellow traffic light indicates that you should drive with caution.

You may cross a single broken line to pass or change lanes as long as you can do so safely and without interfering with traffic.

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.

To turn left from multilane streets and highways, start from the left lane.

If you stop along the road at night, turn on your emergency flashers and leave your low beam headlights turned on. Be sure that other road users will be able to clearly see your vehicle.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This regulation sign means that right turns are prohibited.

You must yield to a stopped transit bus when the bus driver signals to re-enter a traffic lane and there is a flashing "Yield" sign on the back of the bus. Move over or slow down to allow the bus to safely merge back into moving traffic.

When preparing to drive, you should first adjust your seat to ensure that you are in a comfortable position and can see the road clearly. Adjust your mirrors and steering wheel to be effective when your seat is fully adjusted.

This sign indicates that there is a flagger ahead controlling traffic in a construction area.

If you experience a tire blowout, take your foot off the gas pedal and do not immediately apply the brakes. Gradually slow down before gently applying the brakes and pulling off the side of the road.

This sign indicates that the road ahead changes direction at an extreme angle (in this case, to the right). Before you reach such an extreme curve, you should slow down as much as you would when making a turn at an intersection.
