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.

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.

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.
