When the trucks stop it will take a mere 3 days on average for most store shelves to go empty and then no more than 30 days for all warehouses to be empty, and most likely no more than 7 days. During those 3 to 30 days most items will go out of stock too quickly to count on getting any. During that time unrest will happen. Panic will set in. No amount of face time on TV by government officials can possibly quell the unrest. Why the trucks stopped will determine what happens next. If there is a financial collapse then all Hell breaks loose.

"Warehouses" are history. They are now but "distribution" centers - with ONE DAYS supply of goods.
Ask any trucker.
Trucks bringing in supplies for distribution back up to the docks on one side of the building - goods are unloaded and loaded straight into outgoing trucks on the other side of the building.
There is only ONE place left in the country with more than 2-3 days of food on hand: In peoples homes - at least, the smart ones.
And if you're caught IN THE CITY WTHTF, you ain't getting out.
The prudent will have gotten outta Dodge BEFORE -
