The new mStuck module in mCitizen is a revolution for drivers – a collision? You'll do everything on the phone, no papers, no stress.
mBulk – a breakthrough for drivers
Since September 1, 2025, the mCitizen has shown a long-awaited function of mCutch. The module allows you to report traffic collisions directly from the smartphone level – without laborious data copying and printing. This is a response to the increasing number of small bumps on Polish roads – only in 2024 there were over 390 thousand of them.
How does mBump work in practice?
The whole process is divided into intuitive steps:
- Select the Service section in the application menu, then the Driver and vehicles, and click on the mStuck tile.
- Follow the instructions on the screen.
- Set up a common version of the incident with the second driver, both phones must have an active mBump module.
- Each participant chooses in the application whether he is injured or perpetrator.
- Add photos and necessary information – vehicle data and drivers automatically download from the registers, so you don't have to prescribe them manually.
- The application generates QR code – the second participant scans it with his phone to synchronize statements.
Safety and support at the collision site
If an accident/collision requires intervention by the service, the application simply reminds of the need to call 112 and ensure the safety of participants.
