Your vehicle's brake lights indicate to other drivers that you are slowing down or stopping. Your brake lights should always be in working order when you are driving on any roadway.

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

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.

Keep right when another driver begins to pass you on the left. Check for oncoming traffic and adjust your speed to let the passing vehicle move back into the right lane as easily as possible.

White lines are used to separate traffic moving in the same direction. Dashed lines indicate that drivers directly next to the line are permitted to pass when it is safe to do so.

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.

After stopping for a school bus that has its stop arm extended and its lights flashing, watch for children walking along the side of the road. You should always drive with caution when driving near children.

Circular traffic signs indicate upcoming railroad crossings. This sign tells drivers that they are approaching a railroad crossing and should be looking for signs of an oncoming train.

Alcohol is a depressant that negatively affects judgment, vision, concentration, understanding of reality, and reaction time. It is never safe to consume alcohol in any amount before getting behind the wheel of a car.

Keeping a safe following distance will enable you to react to an upcoming problem without the need for a emergency stop, which could cause a driver behind you to crash into the back of your vehicle.

This sign indicates that there is a Y intersection ahead. You must bear either to the right or to the left.

A truck or bus has blind spots on each side, in the rear, and in the front. An automobile cannot be seen in these blind spots. These blind spots are referred to as the “No zone.”

This sign indicates that left turns are prohibited.

When two vehicles arrive to an uncontrolled intersection at the same time, the vehicle on the right has the right-of-way. Once the vehicle on the right has safely passed through the intersection, the other driver may proceed.

Your horn should be used as a warning in situations where you think another driver or a pedestrian does not see you. For example, if a child begins to run into the street in front of your vehicle, you should sound your horn.

This sign warns that the overpass ahead has a low clearance. Do not proceed if your vehicle is taller than the height indicated (in this case, 13 feet, 6 inches).

Driving too fast for conditions is a major cause of motor vehicle crashes. Being inattentive to surroundings can cause a driver to collide with other vehicles. Most rear-end collisions are caused by drivers following other vehicles too closely.

Drivers must be aware that large vehicles often travel at a speed slower than the posted speed limit, especially when driving on an incline, and should use caution when approaching a large vehicle from the rear. When on a hill with limited visibility, it is unlawful to pass another vehicle.

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.

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.

Some travel lanes are designed to carry traffic in one direction at certain times then in the opposite direction at other times. These lanes are separated by a barrier or marked by double broken yellow lines.

In cold or wet weather, you should take special care on sections of road that are shaded by trees or buildings. These areas freeze more quickly than the rest of the road and are the last parts of the road to dry.
