If you are stopped at a railroad crossing with more than one track, do not start moving as soon as a train passes. Wait until you have a clear view down all tracks before you start across. Even where there is only one track, do not start across immediately after a train passes; check again for another train that may be approaching.

Yield the right-of-way to snowplows engaged in work on the roads. Use extra caution in approaching, overtaking, or passing maintenance vehicles and snowplows. Because of their traveling speed and size, snowplows tend to create large clouds of blowing snow that conceal the plow, making it invisible.

When on a roadway with two or more lanes, you should make room for entering vehicles. If there is no one driving next to you, move over one lane.

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.

Warning signs are normally diamond-shaped and yellow, although orange warning signs are used in work areas. Such signs warn that you are approaching a hazardous location or an area where special rules apply.

Do not exceed the school zone speed limit during indicated times. The end of a reduced speed school zone will be indicated by an "End school zone" regulatory sign.

This sign indicates that a divided highway begins ahead. The road splits into two one-way roadways separated by a median or divider. You must keep to the right.

Regulation signs regulate traffic speed and movement, displaying rules which drivers must obey. This sign tells drivers the direction in which they must drive when turning onto a one-way street.

A large truck has large blind spots to the front, sides, and rear of the vehicle. Avoid lingering in these areas. Because of their larger size and weight, trucks require more room to maneuver and stop than passenger vehicles.

You should look and listen for trains before crossing any railroad tracks. If an approaching train is near enough or going fast enough to be a danger, you cannot go across the tracks. This is true even if they have no signals or the signals are not working.

Traffic signs with three sides of equal length warn drivers to slow down when approaching an intersection and to be prepared to come to a complete stop to yield to other drivers or pedestrians. Drivers may proceed when it is safe to do so.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign tells drivers that they may encounter traffic coming from the opposite direction.

A steady yellow light on a traffic signal indicates that a steady red light will soon appear.

If a driver's left arm and hand are extended upward, they are indicating that they intend to turn right. Adjust your driving accordingly if following a driver who is using this hand signal.

Flashing red lights, lowered crossing gates, and/or bells at a railroad crossing mean that you must come to a complete stop. You must not go across the tracks until the lights and bells have stopped and the crossing gates are completely up. Do not drive around or under a gate that is moving up or down.

"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.

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.

Traffic lanes moving in the same direction are separated by broken white lines. You may cross over dashed lines to pass, if it is safe to do so.

When you drive, make sure each person in your vehicle wears a seat belt. In the event of a crash, a person without a seat belt becomes a flying object and a danger to each person in the vehicle.

If you arrive to an open intersection at the same time as a vehicle to your right, you should yield the right-of-way to that vehicle. You may then proceed when it is safe to do so.

When you back up a vehicle, look through your back window for pedestrians and other obstacles. Do not rely only on your mirrors, especially when children are near. Before you back into or out of a driveway, get out of the vehicle and check behind your vehicle.

Before changing lanes, check your side and rearview mirrors for traffic approaching you from behind. Just before you begin moving into the other lane, quickly glance over your shoulder and check for any vehicles that may be in your blind spot.

You must approach all railroad crossings with extreme caution and cross only when you know that no train is coming from either direction. If there is a flagger at a crossing, you must obey all of their instructions.

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

One strategy to avoid driving while impaired or intoxicated is to arrange for a ride home with a friend who does not drink. Drinking coffee or taking a cold shower cannot reduce your blood alcohol content or reduce the effects of alcohol. On average, it takes about an hour for the body to eliminate the alcohol from a single drink.
