UPS Truck Abandoned And Unlocked In Natomas - CBS Sacramento While UPS trucks are known for making deliveries, one box truck with the signature logo was parked overnight on Sierra Point Drive in a Natomas business park fully loaded and unlocked. A local business owner assumed it was abandoned and made calls at 7 in the morning. Plenty of people who work in the area were confused, including long-haul truck driver Harry Singh. “I don’t know it certainly got my head scratching too. I don’t really understand what UPS is doing,” said Singh who added the truck should have been locked with a seal on the rear cargo door.
