As record-high temperatures continue across the nation, there's a new concern for UPS delivery drivers.
In Arizona, a UPS driver struggled to make it onto the front porch of a house. He then collapses and lies down for a moment to recover.
The UPS worker slowly gets back up and reaches for the doorbell before stumbling back to his non air-conditioned truck. UPS says the driver is fine, adding "our package delivery vehicles make frequent stops, making air conditioning ineffective."
