Believe it or not, human beings survived and progressed for thousands of years before the creation of the cell phone. What that means is that there is never anything so dire that it can't wait until you're pulled off the road to make a phone call or text about it. 

When your vehicle's stopped, you can lol and ttyl to your heart's content.

If you use your phone while driving, you run the risk of seriously disappointing your Fairy ShmoopMother. And, you know, crashing and dying. If someone calls you, don't answer it. They have this brand new thing called a "voicemail," that's sweeping the nation. Don't be the last one to hop on the "voicemail" bandwagon.

You definitely shouldn't use a cell phone when driving through construction zones or dealing with any other sort of poor road conditions. Don't talk on the phone if it means that your focus on the road will be sacrificed or compromised. So, if you can't pat your head and rub your tummy at the same time, you're not the type of person who should phone and drive.

At no time should you text message while driving. Doesn't matter if you're the National Texting Champ and can compose a transcription of the Gettysburg Address with your eyes closed. Still shouldn't do it. And besides, you shouldn't be driving with your eyes closed anyway.

Also, if you're going to use a headset or ear buds, don't have them covering both of your ears. You need one ear free in case an Adele song comes on the radio.
