In which scenario is a driver not required to keep a daily log?

A driver is not required to keep a daily log when starting and ending at the same location because this situation typically does not involve extended travel or the use of a commercial vehicle over long distances. Daily logs are generally required for drivers operating under specific regulations, particularly when they are taking longer trips or driving commercial vehicles to ensure compliance with hours of service regulations. If the driver starts and ends their journey at the same location, it indicates a local trip that typically falls within everyday operational routines, which do not necessitate detailed documentation, like a daily log.

The other scenarios would usually require a log for different reasons: when driving less than 80 km, while often exempt for personal trips, specific regulations may still apply depending on the vehicle and its intended use; operating a personal vehicle doesn't automatically exempt one from all requirements of logging, especially if the vehicle is used for business purposes; and maintaining a vehicle maintenance record is separate from the logging requirements, as it pertains to the upkeep and safety checks of the vehicle rather than trip documentation.
