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.

Warning signs are usually yellow with black markings. This sign warns that the divided highway ends ahead. Prepare to change lanes or shift lane position.

You must have evidence of financial responsibility, such as proof of insurance, with you whenever you drive. You must always show proof of insurance and your license to an officer upon request after a traffic stop or collision.

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.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign indicates that there is a steep hill ahead. Slow down and be ready to shift to a lower gear to control your speed and protect your brakes from damage.

You need a longer distance to stop your vehicle on a slippery road than you do on a dry road. Maintain an increased following distance when driving on slippery roads.

It is important that you are able to see clearly through all of your vehicle's windows, including the windshield. Remove all snow, ice, and frost from your vehicle's windows and mirrors before you start to drive.

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

Blue signs on the roadway are service signs. They are used to provide information about motorist services, such as upcoming rest areas, food options, or nearby hospitals.

Driving defensively means anticipating potential errors made by others and preparing to compensate for their mistakes.

Passing on the right is permissible only if it is possible to do so without driving off the roadway. Never pass another vehicle on the shoulder because the other driver will not expect you to be there and may pull off the road.

A driver’s ability to safely operate a vehicle may be impaired at any BAC level, even a level lower than the legal limit. Any amount of alcohol can affect one’s judgment and physical coordination. Driving under the influence of even a small amount of alcohol can lead to criminal charges.

When you are turning left from a two-way street, begin in the lane closest to the centerline and start your turn just before the front of your car reaches the center of the intersection. Do not cut the corner. Steering hand-over-hand, turn into the first available legal lane.

Regulatory signs regulate the movement of traffic. They are usually white with black markings and must be obeyed by motorists.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. This sign warns drivers that another road crosses the highway ahead.

Use low beam headlights when driving in rain, snow, sleet, or fog. High beam headlights in adverse weather conditions lower visibility by reflecting off the precipitation and back into the driver's eyes.

All temporary signs in work zones have orange backgrounds with black writing and/or symbols.

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.

This sign indicates that the road may be slippery when wet. Exercise caution when driving on a slippery road.

This sign alerts you to the possibility of traffic merging into the main stream of travel. After checking to your side and rear, you should move into another lane, if possible, to allow merging motorists a clear path.

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.

You may never drive off the paved or main-traveled portion of the road and onto the shoulder to pass another vehicle.

When a vehicle makes a turn, the rear wheels follow a shorter path than the front wheels. The longer the vehicle, the bigger the difference between the paths of the front and rear wheels. Therefore, long trucks often have to swing wide to complete a right turn.

At a railroad crossing marked with this sign, a driver should look both ways, listen for any trains, and be prepared to stop if any trains are nearby. Never try to outdrive an oncoming train.

The only way to remove the effects of alcohol from the body is to let time pass. Eating, drinking coffee, or taking a shower will not speed up this process.

Hydroplaning is caused by driving too fast on a wet road. Slow down when driving on wet pavement to prevent hydroplaning.

If you are being followed too closely by another driver, merge into a different lane. If there is no lane available for merging, wait until the road ahead is clear and slowly reduce your speed. This will encourage the tailgater to drive around you.

A flashing red light at an intersection means drivers are required to come to a complete stop, yield to traffic and pedestrians, and proceed when the way is clear. The same is true at a stop sign.

When driving on an interstate highway, be aware of upcoming on-ramps. When traffic permits, move out of the right-hand lane to allow vehicles to enter from the on-ramps to your right.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. If you are making a left turn from a one-way street, this means that you would make the turn from the lane nearest to the left curb.

When stopping your vehicle on the roadway, first check your mirrors for traffic. Be aware of surrounding drivers as you release the accelerator and allow your vehicle to slow. Move your foot to the brake pedal and press with steady pressure for a smooth stop.

A truck's blind spots are much larger than a smaller car’s blind spots. The driver cannot see your car behind their vehicle and you can't see what’s happening in traffic ahead if you're driving too closely behind the truck. Whether you are driving behind or to the side of the truck, if you can’t see the driver’s face in their side view mirror, then they can’t see you.

The flashing overhead lights and stop arm on a school bus will be activated when the bus is stopped to load or unload students. If approaching a bus using these signals, you may not proceed until the red lights have stopped flashing and the stop arm has been retracted. Never pass a school bus that is dropping off or picking up students.

While driving, you should remain aware of the actions of surrounding drivers. If you notice an aggressive driver nearby making erratic or improper lane changes, you should not challenge them. The safest way to handle an aggressive driver is to get out of their way.

Alcohol and other drugs can negatively effect a number of skills needed for safe driving, including a driver's reaction time, coordination, alertness, and ability to concentrate.

All roads are slippery and dangerous when wet. This sign warns of conditions that can cause a driver to lose control of a car. A driver should slow down when coming upon wet pavement because it takes longer to stop.

A broken yellow line alongside a solid yellow line means that traffic in the lane next to the broken line may cross the line to pass, while traffic in the lane next to the solid line may not.

It can be hard to judge the speed of oncoming vehicles. They do not always seem to be coming as fast as they really are. Always be sure you can safely change lanes when passing on a two-lane street. If you are not sure of an oncoming vehicle's speed, wait to pass until the oncoming vehicle has passed and you are sure there is enough space for you to change lanes safely.

Only use your horn when it is necessary to avoid collisions. Do not use your horn if a driver or bicyclist is moving slowly and you want him or her to drive faster or get out of your way.
