It's true. UPS mechanics have started putting in new sensors in the UPS trucks. There is a central unit which monitors whether a driver is using their seatbelt, shutting their bulkhead door, and using the parking break. The unit knows whether the truck is moving with a new GPS receiver in the truck. If your truck is moving and your seatbelt and bulkhead door are not on/shut, you may now be fired because of it. If your truck is not moving, and your parking break is not on, same deal. For all of you drivers that are taking shortcuts (not using the seatbelt, shutting bulkhead door, applying parking break) between stops, you'd better rethink how you run your route! These sensors will be put in your truck soon enough. You may as well get in the habbit of slowing down and using the correct methods now. Soon you won't have a choice! Link removed by Cheryl.
