When driving too quickly in wet conditions, your tires may lose all contact with the road surface. Loss of traction will cause the vehicle to ride on top of the water, which is called "hydroplaning." The best way to prevent this from happening is to drive more slowly in rainy or wet conditions than you would when driving during ideal weather conditions.

If a traffic signal is displaying a steady red arrow, traffic in the indicated lane may not proceed in the direction shown by the arrow. Drivers must come to a full stop and wait for a green signal to proceed.

When leaving an alley, driveway, or parking lot to enter a roadway, you must stop before driving onto a sidewalk or sidewalk area. Pedestrians and existing traffic have the right-of-way.

Alcohol slows your reflexes and reaction time, reduces your ability to see clearly, and makes you less alert. As the amount of alcohol in your body increases, your judgment worsens and your driving skills decrease. You will have trouble judging distances, speeds, and the movement of other vehicles.

Driving during the first half hour of rainfall is dangerous because roadways become extremely slippery when the water mixes with oil and other chemicals on the road surfaces that have not yet washed away. Use extra caution when driving on slippery roads.

Because large commercial vehicles have large blind spots on each side, you should avoid driving beside them for long periods of time.

This sign means drivers cannot make a left turn. It is unsafe and unlawful to make a left turn at an intersection where this sign is posted.

Before merging into interstate traffic, you should identify a gap, accelerate to the speed of traffic, and signal. Merge into the gap when it is safe to do so. Be alert to other traffic and do not expect other drivers to clear the lane.

At a four-way stop, the driver who reaches the intersection first should be given the right-of-way by other drivers. If more than one vehicle arrives to the intersection at the same time, the vehicle on the left should yield the right-of-way to the vehicle on the right.

If a tire blows out or suddenly goes flat while you are driving, grip the steering wheel firmly and keep the vehicle aiming straight. Take your foot off the accelerator and do not brake.

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.

Driving above the speed limit, driving too far below the speed limit, and driving too fast for conditions are all actions that commonly contribute to traffic accidents. Always drive with the general flow of traffic, within legal speed limits.
