Drivewyze® PreClear is the trucker app that saves you time, money and hassles, by letting you bypass weigh stations using your iOS device across North America. For a complete and updated list of supported states and sites, visit http://drivewyze.com/coverage-map. The Drivewyze app automatically detects the location of weigh stations and alerts the driver when the vehicle is 2 miles from an inspection site. Next, the app sends a bypass request, and notifies the driver to either BYPASS or PULL-IN when the vehicle is one mile away. --- New users are automatically given a 30-day complementary trial upon account sign-up. When this trial expires it will NOT auto-renew. You will need to Subscribe to continue to receive bypasses. Payment will be charged to your iTunes Account upon confirmation of purchase. Subscription automatically renews every 30 days unless cancelled at least 24-hours before the end of the current period. Cancellations can be done through your iTunes Account or through Manage Subscriptions via the in-app-menu. Any unused portion of a free trial period, will be forfeited if the user purchases a subscription. EULA: https://drivewyze.com/about-us/policy-center/end-user-license-agreement-apple/
