You should always signal when moving your vehicle to the right or left. On an interstate, you should stay in the right lane if you are moving more slowly than the surrounding traffic. It is illegal to back up or make a U-turn on interstate highways, so if you miss your exit, you should proceed to the next exit.

Even when you signal, you should not assume that the space you want to occupy is free or that other drivers will give you the right-of-way.

By definition, blind spots are areas that cannot be seen using your mirrors. To check your blind spots, you should look over your shoulders.

A double solid yellow line down the center of a road indicates that traffic is moving in opposite directions and that passing is not allowed from either direction.

While it can create special problems for large vehicles, strong wind can cause problems for all drivers. Wind can lower visibility by blowing dirt and dust into the roadway, but it can sometimes also physically move a vehicle.

Pedestrian crosswalks are often shown by white, solid lines to emphasize pedestrian crossing points. Crosswalks may have additional lines between the white, solid lines or in place of the parallel lines. However, crosswalks may also be unmarked.

Expect a train on any track, at any time, traveling in either direction. If you need to stop after crossing the tracks, wait until you can completely cross the tracks before proceeding. Make sure your vehicle clears the tracks before you stop.

If a road has four or more lanes with two-way traffic, drive in the right lanes unless you are passing or turning left. If you are on an interstate highway and are driving below the speed of the flow of traffic, use the right lane.

This sign warns of two-way traffic.

When passing is permitted, look for both headlights of the passed vehicle in your rearview mirror. Only then may you safely return to your original lane.

Make room for vehicles that are entering a freeway. If possible, merge into the next lane to create a gap for the incoming vehicles. If you cannot merge, adjust your speed to allow for the vehicles to enter traffic as smoothly and safely as possible.

When broken yellow lines separate the lanes of traffic on a two-lane roadway, any driver may pass when there is no oncoming traffic.

The only way to remove the impairing effects of alcohol is to give the body time to remove it from the body. Drinking coffee, physical activity, or taking a cold shower will not speed up this process. It takes about one hour to cancel the effects of one drink.

Always be aware of pedestrians near your vehicle. You must do everything you can to prevent striking a pedestrian, regardless of the circumstances.

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

While waiting to turn left, keep your wheels pointed straight ahead until it is safe to start your turn. If a vehicle hits you from behind, this will prevent you from veering into oncoming traffic. When parked facing either uphill or downhill, turn the wheels so the vehicle will not roll into traffic if the brakes fail.

Legal medications, both prescription and over-the-counter, can impair your ability to drive. They can be particularly dangerous when used in combination with alcohol.

Before beginning a right turn, use the appropriate signal to give surrounding drivers adequate notice of your intentions. Slow down and approach the intersection from the right lane, staying as close as is practical to the right curb or edge of the roadway.

Even if a vehicle is properly equipped with rearview and outside mirrors, it still has blind spots that cannot be seen in the mirrors. Large trucks have much larger blind spots than most passenger vehicles.

Excessive speed is one of the most common contributing factors to vehicle crashes. Excessive speed does not save time and often leads to high-risk decision-making.

If your vehicle begins to skid, do not use the brakes. Braking could make the skid worse.

Pennant-shaped yellow signs like this are used to indicate a no passing zone.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. These signs may be accompanied by speed advisory plaques that indicate the speed with which you should proceed.

You must come to a complete stop at a steady or flashing red traffic light. You must always obey instructions given by officers directing traffic, regardless of any posted signs or traffic signals.

All temporary signs in work zones have an orange background with black letters or symbols. These signs are found on the right side of the road, or on both the left and right sides if the roadway is a divided highway.
