The form can be accessed on USPS-issued mobile devices through the Informed Mobility Safety Observation Tool (IMSOT).
PS 4584-T is specifically designed for tractor-trailer drivers, who have requirements different from operators of other postal vehicles.
Managers and supervisors can use a desktop computer to enter data from paper PS 4584-T forms into the lMSOT online dashboard. They can also go to the Blue home page, type IMSOT into the URL bar and be taken directly to the tool’s dashboard.
Alternatively, managers and supervisors can use the IMSOT icon on their mobile devices to access the application and enter the data.
For IMSOT technical assistance, call the USPS Help Desk at 800-877-7435 and say “IMSOT” when prompted.
