Drive a car, not a cell phone
If the keys are in the ignition, the phone should be powered off. If you're driving with children, keep in mind that kids don't normally disappear into thin air --- so it's okay if you stop looking at them and concentrate on the road instead. No matter what it is, avoid distraction and focus on the task in hand --- driving.

Share the road
The Golden Rule applies to driving -- in fact, it should be a law. When you share the road, you put everyone in a good mood, avoid accidents and arrive at your destination in a friendly frame of mind. Try it: the next time someone is attempting a last minute lane change, be courteous and let them into the lane. Not only have you avoided a fender-bender, but you've also done a good deed. Bravo!
