How do I avoid toll routes and highways on Google Maps for iOS?

Your iPhone’s Google Maps app will select the shortest route for you by default, whether there are tolls, highways or ferries along the way or not. You can have it route you around these features though, if you want. To avoid tolls, highways or ferries, type in your destination and tap on the car symbol to get directions, then tap on the button to the right of your start point.
