I try to register and it tells me invalid number, had other people try it incase of operator error, not working for them either. Hope they fix it ### 5/5 — Saved me £65 *2023-01-13, version 2.3* Great App. It saved me from going down a penalty restricted road. ### 5/5 — Great utility app for your day to day travel *2022-07-25, version 2.2* Excellent a must download ### 5/5 — Really helpful! *2021-08-19, version 1.0* Great app to have on in the background whilst commuting. Managed to save time avoiding traffic hold ups. Loved the “traffic warden” feature too, not seen that on any other traffic app- nifty way to avoid the fines! Would recommend. ### 5/5 — Genius! *2021-08-19, version 1.0* No more parking tickets! Amazing concept to help keep the warden away! ## Frequently asked questions about 4Warning ### What is 4Warning? 4Warning is a location-based app that alerts users within a half-mile radius of live hazards or traffic disruptions.
