Before changing lanes, you should look in your rearview and side mirrors to make sure no one is trying to pass you. You should also look over your shoulder to make sure that no one is in your blind spot.

This sign indicates that the road ahead changes direction at an extreme angle (in this case, to the right). Before you reach such an extreme curve, you should slow down as much as you would when making a turn at an intersection.

Any eight-sided sign is a stop sign. At an intersection with a stop sign, you must stop completely and check for pedestrians and cross traffic in the intersection. Wait for the intersection to clear before proceeding.

Drivers must yield to pedestrians when they are crossing at any intersection without a traffic light, whether or not there is a crosswalk.

When exiting a highway, you should get into the exit lane well in advance. Do not begin to slow down until after you have moved into the exit lane.

Because hydroplaning is caused by driving too quickly in wet conditions, the risk of it happening can be reduced by driving more slowly.

The only way to be sure you will have enough time to react to mistakes made by other drivers is to leave plenty of space between you and the vehicles around you.

This one-way sign indicates that traffic flows only in the direction of the arrow.

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.

A flashing red traffic signal has the same meaning as a stop sign. At an intersection with a flashing red light, you must come to a complete stop, look both ways, and proceed only after the intersection is clear.

When driving near heavy trucks, other drivers and highway users must make allowances for the increased stopping distance required by the large vehicles. Drivers of smaller vehicles should remain in locations where they can be seen by the driver of the large vehicle and where their view of traffic is not blocked by the vehicle.

Penalties for a first offense of driving under the influence include a fine of between $300 and $5,000, depending on your blood alcohol concentration level.

Crashes often happen when some drivers go faster or slower than other vehicles on the road. Always try to drive with the flow of traffic, within the posted speed limit.

If you are stopped by the police, keep your hands on the wheel and ask any passengers to keep their hands in view as well. You should remain in the vehicle unless the police officer asks you to get out. Wait until the officer asks you to retrieve your driver license, registration, and insurance cards.

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.

Solid white lines are used to separate lanes traveling in the same direction (as well as to mark the right edge of the road). Broken white lines separate lanes traveling in the same direction and may be crossed to pass. Yellow lines separate lanes of traffic moving in opposite directions.

Compared to signs and other roadside objects, pedestrians are hardest to see at night.

To complete a turn safely, you should signal three to four seconds before turning.
