When parking either uphill or downhill on a road that has no curb, you should turn your wheels so that the vehicle will roll away from the center of the road if the brakes fail.

Signs with a red circle and diagonal line over a black symbol indicate that the action represented by the symbol is prohibited. In this case, the sign indicates that left turns are prohibited.

Warning signs are usually yellow with black markings. This sign warns the driver that there is an upcoming winding road. Speed should be adjusted appropriately.

Check your mirrors for quickly approaching vehicles when you are driving down hills or mountains. Vehicles often build up speed while traveling down a steep grade. Be alert to large trucks and buses that may be going too fast.

Yellow lines mark the center of a road used for two-way traffic. A solid yellow centerline indicates that drivers may not cross the line to pass. A broken yellow centerline indicates that drivers may cross the line to pass, but only if passing would not interfere with traffic.

Continuous hard braking on snow and ice can result in the locking of the front brake, causing a loss of steering. To avoid the need for excessive braking, make sure to maintain an appropriate speed for conditions.

You should always signal when turning, changing lanes, slowing down, or stopping so that other drivers, motorcyclists, bicyclists, and pedestrians will know your intentions.

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.

It is not advisable to drive after drinking any amount of alcohol. Even a single drink will affect your ability to drive safely.

Drivers must obey special signs or instructions given by flaggers. They are in place to keep drivers and workers safe.

This sign indicates that there is a pedestrian crosswalk.

Alcohol reduces all of the important abilities you need to drive safely. Alcohol goes from your stomach to your blood, then from your blood to all other parts of your body. Alcohol affects the areas of your brain that control judgment and skill.

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.

A pennant-shaped sign marks the beginning of a no passing zone.

A double yellow centerline means that it is prohibited for traffic from either direction to cross the centerline to pass.

Yellow lines separating lanes of traffic indicate that traffic is moving in opposite directions. Double solid lines indicate that passing is not permitted from either direction.

The acceleration pedal should be pressed slowly and smoothly. Depressing the gas pedal too quickly can cause your wheels to overspin, making it difficult to control your vehicle.

Make room for vehicles that are entering a freeway. If possible, merge into the next lane to create a gap for the incoming vehicles. If you cannot merge, adjust your speed to allow for the vehicles to enter traffic as smoothly and safely as possible.

A five-sided sign is used to alert drivers to a school zone. Some pentagonal signs specifically indicate crosswalks within school zones where children or other pedestrians may be present.

Any time you come to a place where people may cross or enter your path, or where one line of traffic meets another, you should look to the left and right sides of your vehicle to make sure no one is coming.

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.

Because large trucks require more time to accelerate than smaller vehicles, trucks can lose speed driving up long or steep hills. Be cautious when driving behind a large truck and be sure to give the vehicle additional space, especially when driving on an incline.

This sign indicates that a divided highway begins ahead.

Motorcycles can stop quickly and following them too closely endangers your life and that of the motorcyclist. If the motorcyclist makes a mistake, you need to have enough time and space to avoid a crash.
