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

If it feels like your tires have lost contact with the surface of the road, you should ease your foot off the gas pedal and stay off the brakes. Do not try to stop or turn until your tires are gripping the road again.

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.

If you become tired while driving, it is best to stop to rest or change drivers. Being tired dulls your mind and slows down your reactions, making driving hazardous.

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.

A red arrow means "stop." You must remain stopped until a green light or green arrow appears. Do not turn against a red arrow.

Instructions given by police officers directing traffic always override posted traffic signals and signs. Follow the officer's instructions.

Allow for extra space when driving behind a motorcycle. Motorcycles can stop more quickly than other vehicles can and you must have adequate room to stop if the motorcyclist brakes or falls off. Also, remember that motorcycles are difficult to see at night because they only have one tail light.

Any amount of alcohol acts as a depressant, slowing the function of the nervous system. It will reduce a person's alertness and ability to concentrate, increase their reaction time, and drastically reduce their coordination.

It is necessary to follow farther behind a large truck than you would if following a passenger vehicle because trucks have larger blind spots.

When driving behind another vehicle, allow at least one car length of space in front of your vehicle for every ten miles per hour of your driving speed. As your driving speed increases, your stopping distance also increases. Allowing space in front of your vehicle will help you to safely stop or maneuver if you encounter an unexpected hazard.

Blind or partially blind pedestrians may carry a white cane or use the assistance of a guide dog. You must yield the right-of-way to a pedestrian with a guide dog or a white cane.

Avoid "rubbernecking," or slowing down to look at collisions or anything else out-of-the-ordinary. This helps to relieve traffic congestion.

It is not always easy to maintain a safe distance behind your vehicle. However, you can help keep the driver behind you a safe distance away from your vehicle by maintaining a steady speed and signaling turns, lane changes, and deceleration in advance.

If a tire suddenly goes flat while you are driving, hold the steering wheel tightly and keep the vehicle moving straight. Slow down gradually by taking your foot off the gas pedal and using the brakes lightly.

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.

A round yellow sign indicates that there is a railroad crossing ahead.

You should always slow down before entering a curve. You may not be able to see hazards ahead and braking in a curve may cause your vehicle to skid.

Use your low beam headlights when driving in fog, rain, or snow. High beam lights can reflect off the weather conditions, lowering visibility even more.

Not getting enough sleep is a cause of poor driving behavior. Just like drugs and alcohol, sleepiness slows reaction time, decreases awareness, and impairs judgment.

When making any turn, turn from the lane closest to the direction you wish to travel into the first available legal lane. On a turn from a two-way to a one-way street, this means you should turn into the first lane.

This sign marks the presence of a crosswalk. Be alert to any pedestrians that may be crossing the roadway.

It is important to remember that driving is a privilege and that all drivers play a role in ensuring that everyone remains safe on the roadways. If you prove to be abusive of that privilege, the privilege may be revoked.

This sign indicates that there is a pedestrian crosswalk.

When the center of the road is marked by a solid yellow line beside a broken yellow line, passing is permitted from the side next to the broken line and prohibited from the side next to the solid line.

"No zones" are areas around trucks or buses in which cars disappear into the larger vehicle's blind spots. "No zones" can also be defined as areas in which cars are so close to the larger vehicle that they restrict the truck or bus driver’s ability to stop and maneuver safely. A car being in a "No zone" greatly increases the potential for a crash.

This sign warns that a steep downgrade is ahead on the road. Drivers should check their brakes.

To prevent skidding on slippery surfaces, you should shift to a low gear before going down a steep hill. You should also follow farther behind the vehicle in front of you than you normally would. Quick stops should be avoided. Unless you have antilock brakes, pump the brakes to slow or stop.

When driving in a work zone, keep a safe distance between your vehicle and traffic barriers, trucks, construction equipment, workers, and other vehicles. Increase your following distance and do not tailgate.

Drivers are responsible for making sure their vehicles do not become hazards after they have been parked. Wherever you park, make sure your car is visible to drivers approaching from any direction.
