No, you don’t need the Uproad app open to pay tolls with Uproad. In fact, you don’t even need your phone with you. 

Once your vehicle is activated, the toll agency uses your license plate to confirm your tolling activity. The tolling agency will send a toll bill to your Uproad account for payment. It usually takes 3-30 days for an agency to post their toll bill to your account.

If you'd like to immediately see estimated toll costs as you drive, turn on Toll Alert.  This will track your expected toll bills based on your location. Make sure the Location and Motion & Fitness permissions are enabled in your phone settings as they are required for Toll Alert to work.
