When a school bus is stopped on the road ahead with its lights flashing and its stop arm extended, you must come to a complete stop and wait to proceed until the lights have stopped flashing and the stop arm is withdrawn.

You may drive more slowly than the posted speed limit, based on road conditions, but it is illegal to drive any faster than the posted speed limit. Some conditions which require reduced speed for safety include approaching curves or hills where visibility is limited, driving on slippery roads, and driving on roads where animals and pedestrians are present.

When passing, use your right turn signal after entering the left lane and before returning to the right lane. It is safe for you to return to the right lane when you can see the entire vehicle you have just passed in your rearview mirror.

Before changing lanes, it is very important to check behind you. You should look over your shoulder to ensure that you are not getting in the way of vehicles in the lane you want to enter. Before changing lanes, you should also ensure that no drivers are attempting to drive into the same spot from a different lane.

As driving speeds increase, the chance of a fatality in the case of a collision increases. If you are going faster than 80 miles per hour, you have almost no chance of living through a crash.

The speed limit in a school zone is 15 mph. Drive with extra caution when driving where children or other pedestrians may be present.

Drivers should check their rearview mirrors often to stay aware of the position of traffic behind them.

If you see a blind person attempting to cross a street within a crosswalk or at an intersection, take every precaution and extend every courtesy. Allow them to safely cross the intersection before you proceed.

Warning signs are usually yellow with black markings. This sign warns drivers that the roadway will be slippery when wet and they should reduce their speed accordingly.
