When parking uphill on a road that does not have a curb, your front wheels should be turned to the right (toward the edge of the road). This will ensure that the vehicle will roll off of the road if the brakes fail.

Low beam headlights should be used in fog, rain, and snow. The light from high beams will reflect back to the driver under these weather conditions, causing a glare that will make it difficult to see ahead.

Warning signs are usually yellow with black markings. They alert you to conditions that are immediately ahead. There may be an upcoming change in traffic direction, a steep downgrade, or another potentially hazardous situation that requires action on the part of the driver.

Blood alcohol concentration (BAC) is a measure of the percentage of alcohol in a person's blood. The higher the BAC, the more impaired a person is.

Warning signs are usually yellow with black markings. Warning signs may alert drivers to areas where animals, people, and vehicles are likely to cross traffic.

You should enter a freeway at or near the speed of traffic, unless the speed of traffic exceeds the legal speed limit.

Because your tires will not grip the road under wet, snowy, or icy conditions as well as they will under dry conditions, you should slow down if the roadway is wet or icy.

A broken yellow centerline means that a driver may cross the centerline to pass another vehicle on the left as long as there is no oncoming traffic. Drivers should never cross a solid yellow centerline in order to pass.

When approaching a railroad crossing, you must look, listen, slow down, and prepare to stop. Let any trains pass before you proceed.

This sign prohibits right turns. It is illegal to turn right at an intersection where this sign is posted.

Children on bicycles are sometimes unpredictable. Young bicyclists are especially likely to make surprising changes in direction. Remember that children and bicycles are both small in stature and may become difficult to see.

You may turn left onto a one-way street that moves to the left if there is no sign prohibiting the turn. You may not turn left onto a one-way street where traffic moves to the right.

Warning signs are usually yellow with black markings. This sign indicates the presence of a crosswalk, regardless of if it is marked on the pavement or not. Upon seeing this sign, you should be alert and allow any pedestrians to cross the road safely.

Remember that all medications, prescription or over-the-counter, are potentially dangerous and could impair your driving. Over-the-counter medicines that you take for colds and allergies can make you drowsy and affect your driving ability. It is your responsibility to know how your medication affects your ability to drive.

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.

Rumble strips create noise and vibrations to warn drowsy or inattentive drivers that they are straying off of the road or are approaching a stop sign or signal.

If possible, try to only deal with one roadway hazard at a time. If you want to pass a pedestrian but an oncoming vehicle is approaching, slow down and let the vehicle pass. You may then pass the pedestrian if it is safe to do so.

Alcohol is a depressant that dulls your judgment and makes your reflexes unreliable.

If your vehicle breaks down on a highway, make sure other drivers can see it. Get your vehicle off the road and away from traffic if at all possible and turn on your emergency flashers to show that you are having trouble.

This sign indicates that turns in the direction of the arrow (in this case, to the right) are prohibited.

This sign warns of of an approaching traffic signal.

An eight-sided red sign means "stop."

A diamond-shaped yellow sign warns of possible danger ahead. Orange signs, which are mostly diamond-shaped, are used to warn of possible dangers in or near work areas.

When parallel parking, your wheels should be parallel to and within two feet of the curb. Only park where you will not be disruptive to traffic and where drivers can clearly see your vehicle from both directions.

If a vehicle merges in front of you too closely, take your foot off of the accelerator. This will create space between you and the vehicle ahead without requiring you to slam on your brakes or swerve into another lane.
