You're team-driving a load of Division 1.1 explosives with a co-driver who also holds a CDL with a hazmat endorsement. You want to go inside to eat while your co-driver stays with the truck. Is this acceptable under the attendance rule?

49 CFR 397.5(d)(2) (qualified representative — carrier designation, awareness of hazards, emergency instruction, and ability to move the vehicle)

Team driving is a practical way to keep explosives attended without forcing one driver to go without food or rest for an entire trip. Knowing that a properly designated and briefed co-driver can legally stand in for attendance purposes lets teams plan breaks safely and legally, instead of assuming the load must sit unattended or that only one specific person can ever watch it.
