Remaining Driving Time (RDT)

Plan every journey with confidence

Every transport company faces the same challenge: keeping vehicles moving while remaining fully compliant with European driving and rest time legislation.

The Remaining Driving Time Parameter Group provides real-time insight into the driver’s remaining legal driving time, required breaks and mandatory rest periods.

By making this information available to planners, dispatchers and fleet management systems, transport companies can optimize planning, avoid unnecessary delays and reduce the risk of costly fines.

Simplifying Remaining Driving Time for Smarter Planning

Driving and rest time regulations are among the most complex rules in road transport.

Daily limits, weekly limits, mandatory breaks, compensation periods and reduced rest periods all influence whether a driver may continue driving.

The Remaining Driving Time Parameter Group continuously interprets this information directly from the tachograph and presents it in a simple, harmonised format that can immediately be used by planning and fleet management applications.
