Bus routes

It's after school. Do you know where your kid is? With Dallas ISD's new bus route app, finding out where your young scholar is located is easy. The school district rolled out the free MyStop app Monday. It can tell parents the location of their kid's assigned bus and (within a 10-minute window) the estimated time of arrival for bus stop pickup time.

The app is secure, and will not work without a DISD username and password. To download it, type in "Versatrans My Stop" in your app store. It's available on both Apple and Android phones.
