500 vehicles, one system: How Müller Service GmbH digitally reorganized its driver’s license check with Carano

12.03.2026

Müller Service GmbH manages a fleet of around 500 vehicles and 420 drivers at several locations. As the size of the fleet grew, so did the organizational effort required for the legally prescribed driver’s license checks. In this case study, we show how the company digitized and structurally reorganized the process with liva from Carano.

500 vehicles, 420 drivers - and the obligation to regularly check driving licenses

Müller Service GmbH manages around 500 vehicles with 420 drivers at several locations. In such a structure, checking driving licenses is not an administrative side issue, but a central component of owner responsibility.

Companies are obliged to regularly check the validity of the driver’s license. This check must be documented in a legally secure manner and be verifiable at any time in the event of a claim.

As the fleet grew, it became clear that the previously manual driver’s license checks were causing increasing coordination costs, media disruptions in documentation and a lack of transparency in fleet management.

The question was therefore no longer whether to go digital, but how to reorganize the structure of driver’s license checks.

From manual inspection to system-supported inspection

The previous manual control meant:

Physical presentation of the driver’s license
Personal examination by superiors
Paper-based documentation
Decentralized storage
Individual memories

Regular checks had to be carried out on 420 drivers to ensure that they had a valid driver’s license. Each check had to be carried out and stored in a traceable manner.

Coordination was particularly difficult for drivers in the field. Inspection intervals were handled differently, reminders had to be sent manually and the documentation could not be accessed centrally.

This created an organizational risk for the fleet manager.

Driving license check app: the operational linchpin

With liva from Carano, the electronic driver’s license check has been fully integrated into a digital system logic. At the heart of the solution is the driver’s license check app.

After a one-off initialization of the driver’s licenses with RFID chips, the electronic driver’s license check is carried out via smartphone.

Drivers scan their driver’s license independently.
The check is carried out automatically.
The documentation is completely documented in the system.

This fundamentally changes the nature of control:

Physical presentation no longer required
No deadline logistics
No manual tracking
Automatic reminders for upcoming exams
Central overview of the fleet

The driver’s license check app ensures that every check is carried out regularly and is monitored by the system.

Automated processes instead of individual responsibility

A decisive difference to manual driver’s license checks lies in the automation.

liva defines test intervals digitally
Reminders are sent automatically
Overdue checks are immediately visible
The inspection is fully documented

For fleet managers, the introduction of electronic driving license checks means one thing above all: complete transparency. They receive a clear status overview of all drivers, can see at a glance which checks have been carried out and where action is required. At the same time, liability risks are noticeably reduced as every check is documented in a traceable manner.

As a result, driver’s license checks are no longer perceived as isolated individual checks, but as a standardized and firmly integrated component of professionally organized fleet management.

Legally compliant documentation as a safeguard

In the context of owner liability, it is necessary to carry out regular driver’s license checks. The decisive factor here is not only the check itself, but also the complete documentation.

With liva from Carano, every electronic driver’s license check is saved:

Date of the test
Validity status
Review carried out
History of all controls

In the event of a claim, it can be proven immediately that the driver’s license has been checked.

The driver’s license control app acts as an operational tool – liva as a documenting system platform.

Driver's license verification

Are all your employees in possession of a valid driver’s license? With Carano’s electronic driver’s license check, drivers conveniently scan their license on the go via smartphone app. All results are fully documented.

Integration into the entire fleet management system

The driver’s license check app is not an isolated tool at Müller Service GmbH, but is fully embedded in the fleet software Fleet+ from Carano. This means that the electronic driver’s license check is not an independent process alongside other tasks, but part of a centrally controlled fleet management structure.

In addition to driver’s license checks, Fleet+ is used to digitally manage all vehicles, systematically plan and monitor maintenance appointments, document damage processes in a structured manner and transparently analyse costs. All relevant data – from driver information and vehicle-related inspections to key business figures – converge on a common platform.

This means that the driver’s license is not checked separately, but in direct connection with all other processes in the fleet. This creates consistent processes, avoids media disruptions and ensures that information does not have to be maintained twice. Changes to drivers or vehicles automatically affect the respective inspection and documentation processes.

This central system architecture is particularly crucial for a fleet with 500 vehicles and 420 drivers. The larger and more complex the fleet, the more important it is to have an integrated solution that links all processes together and ensures end-to-end transparency. The fleet management software Fleet+ forms the organizational foundation on which the electronic driver’s license control is reliably and permanently anchored.

Scalability for growing structures

The electronic driver’s license check via app can be configured flexibly. Different driver groups can be stored with individual check intervals.

New locations or additional vehicles can be easily integrated.

In group structures in particular, driver’s license checks become a standardized, company-wide process.

Conclusion: The driver's license check app as a structural component of modern fleets

With liva from Carano, Müller Service GmbH has not only digitized its driver's license checks, but systematically reorganized them. Today, checks are carried out electronically, regularly, automatically and transparently.
The driver's license check app relieves drivers and fleet managers alike. At the same time, liva ensures that every check is documented and traceable.
With 500 vehicles in particular, it is clear that an electronic driver's license check is not an additional module, but a central control instrument in professional fleet management.
