White lines separate traffic lanes traveling in the same direction. You may cross broken white lines to pass, as long as the passing lane is clear.

While it is always dangerous to drive too fast on slippery roads, this is especially true when driving in turns and curves. Be sure to approach them more slowly in slippery conditions than you would under normal circumstances.

Observe posted speed limits in school zones. There are increased penalties for violation of school zone speed limits.

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

When driving on wet roads, drivers should increase their following distance.

Consuming even a small amount of alcohol will impair your vision, judgment, concentration, and coordination.

If your wheels drop off the pavement and onto a low shoulder, you should reduce your speed without braking and very carefully turn back onto the pavement. Be aware of any nearby traffic when re-entering the road.

If you are entering traffic from a driveway or private road, you should yield to drivers already on the public road. Merge safely into traffic when you are able to do so.

You should always slow down when driving on narrow or winding roads, near intersections, near railroad crossings, on hills, in sharp or blind curves, where there are pedestrians or driving hazards, and when the roads are wet or slippery.

A stop sign means that you must come to a full stop and yield the right-of-way to vehicles and pedestrians in or heading toward the intersection. Go again when it is safe.

This sign indicates that there is a railroad crossing on the road ahead. You should always slow down when approaching a railroad crossing. Trains cannot yield to cars, so you must let them pass before crossing the tracks.

When you see any signs indicating a nearby railroad crossing, you should slow down, look for a train, and be ready to stop. If the red warning lights are flashing or the gate is down, you must stop 15 to 50 feet before the railroad tracks. Do not try to go around the gate.

One situation where it is appropriate to use your horn is if you lose control of your vehicle. In this case, sound your horn to alert other drivers.

It is prohibited to park on the shoulder of a freeway, except in an emergency.

A green steady arrow means you may pass through the intersection in the direction that the arrow is pointing. Oncoming traffic is required to stop for turning traffic.

This sign warns drivers that the divided highway ends ahead.

A steady red traffic light indicates that drivers must come to a complete stop. Driving through a red light is against the law and is extremely dangerous. Drivers may turn right on a steady red light if there is no sign prohibiting a turn on red.

When entering a roundabout, you must yield to pedestrians, bicyclists, and vehicles that are already in the roundabout.

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

When you are approached by an emergency vehicle that is using its lights, sirens, and/or other warning devices, you must immediately drive to the right side of the road and stop.

Warning signs prepare drivers for upcoming road conditions and hazards and are usually yellow with black markings. This sign warns drivers about an upcoming steep hill. They should adjust their speed accordingly to avoid brake damage or collision.

Double solid yellow lines are used to mark roadways where passing is prohibited from both directions. You may cross these lines only to make a left turn into or from an alley, private road, or driveway.

Chevron signs like this indicate that the road curves sharply in the direction indicated by the chevron (in this case, to the left). There may be several chevron signs placed throughout a curve.

A speed limit sign shows the maximum legal driving speed for the stretch of highway where it is posted. Driving safely may require you to travel more slowly than the posted limit. When conditions are less than ideal, drivers should slow down.

When you hear the siren or see the flashing lights of an emergency vehicle coming from behind your vehicle, you must create a clear path for the emergency vehicle and stop. Reduce your speed and safely pull over to the side of the road. If the emergency vehicle is directly behind your vehicle when you are in heavy traffic, keep moving slowly until you can get out of its way.

When turning left, drivers must yield the right-of-way to oncoming traffic. Drivers must also always yield the right-of-way to pedestrians, bicyclists, and other drivers who are already in the intersection.

This sign provides advance warning that bicycles may be present.

A sign with a red circle and slash over a symbol indicates that the action represented by the symbol (in this example, a right turn) is not allowed.

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

Your physical condition has an important bearing on your ability to drive safely. Drivers should be aware of their physical limitations and only drive if it is safe to do so.

Drugs (including illegal, prescription, and over-the-counter medications) can affect your brain function and impair your ability to drive safely. Combining alcohol with other drugs will increase the risk of a crash.

It is estimated that drivers make 200 decisions for every mile traveled, making it vital that drivers focus their full attention on the task of driving. Performing any additional task can create a dangerous distraction.

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

Railroad crossing warning signs are used to warn drivers of the possibility of a train. Drivers should obey all railroad crossing warning signs and never go around barriers or disregard the warning sign.

Your ability to stop is greatly affected by the condition of the road. You need to reduce your speed when road conditions are poor in order to maintain control of your vehicle. You will be at risk if you are driving too quickly on roads that are slippery and you need to stop.

Driving more slowly than the flow of traffic can be hazardous. If you are on a two-lane, two-way road and driving so slowly that traffic is backing up behind you, you are required to pull off the road and let the other vehicles pass. Only drive significantly under the speed limit when conditions require it.

You should slow down at the first sign of rain, snow, or sleet, all of which can create slippery road conditions. When conditions on the road are less than ideal, safety may require that you drive more slowly than the posted speed limit.

When there is more than one potential hazard on the road, you should ensure that you only have to deal with one of them at a time. For example, when there is a bicyclist on the right that you want to pass and an oncoming car to the left, you should not try to squeeze between both at the same time. Instead, let the oncoming car pass, and then pass the bicyclist.

If your vehicle begins to skid, remain calm. Steer in the direction that you want to go and try not to overcorrect.

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.
