Driver Controls (DRC)
Improve driver safety through vehicle awareness
For many professional vehicles, safety depends not only on how the vehicle is driven, but also on what happens inside the cab.
The Driver Controls Parameter Group provides real-time information about driver actions, vehicle controls and cabin status. It enables fleet operators to monitor operational procedures, improve driver safety and verify compliance with company policies.
This Parameter Group is particularly valuable for emergency services, hazardous goods transport, waste collection, cash transport and other specialist vehicles where operational procedures directly affect safety.

Business Value
The Driver Controls Parameter Group helps organizations verify that operational safety procedures are followed.
Examples include:
Confirming that emergency vehicles only exceed normal traffic rules when emergency equipment is activated.
Monitoring whether drivers wear seat belts during operation.
Detecting unsafe driving situations with open doors or tailgates.
Verifying safety procedures for hazardous goods transport and other high-risk operations.
Supporting incident investigations with objective operational data.
The result is improved safety, reduced operational risk and better compliance with internal procedures.
Why Squarell?
Most telematics systems provide only basic vehicle information, typically through the standard FMS interface.
Squarell goes beyond FMS by accessing additional OEM vehicle networks, making a much wider range of cabin and driver-related information available.
This includes driver actions, lighting status, seat belts, doors, wipers and other operational signals that are often essential for specialist fleet applications but are rarely available through standard telematics solutions.
