Did you know that you can set up your iPhone send a caller an automatic text reply any time you get a call?
This enables you to let them know that you are driving and that you will call them back later. It does this without you needing to touch your phone!
Step by Step
First, go to settings and click on Do Not Disturb.

Scroll down to DO NOT DISTURB WHILE DRIVING

Tap the options next to Activate. I chose ‘Automatically’ so that when I am in a car, this option automatically turns on.

Next to Auto-Reply To, chose which calls will get this response.

Next to Auto-Reply, you can choose what your automatic text reply message will say.

What it Looks Like to the Caller
When someone calls you while you are driving, the caller will receive your personalized text message, and know that you will call when you are available.
