Turn your phone off (or at least on silent/do not disturb) and put it either in the back seat or the seatback pocket before getting behind wheel. Get a Garmin offline GPS for navigation. If you want entertainment like music, audiobooks, or podcasts you can get a cheap, basic MP3 player and load it up before car trips and plug it into the aux input. Though, honestly, this might not be necessary as long as the phone is out of reach and alerts are off/on silent; so a phone with notifications disabled bluetooth streaming podcasts from the back seat should be fine. The important thing is its entirely out of your reach and you don't hear the notifications.
