No Trucks Sign: Meaning and What to Do
The white square with a red circle and slash over a truck silhouette prohibits trucks from the road ahead. It is posted where a road cannot carry heavy vehicles, where a residential street is protected from through freight, or where a low bridge or tight turn makes trucks unsafe.
No Trucks Sign
The red circle with a diagonal slash is the standard prohibition symbol on American signs. Whatever sits inside the circle is what is forbidden, so the same design says No Bicycles, No Pedestrians, or No Trucks depending on the symbol.
What to do when you see the no trucks sign
If you are driving a truck, do not enter; find the posted truck route or another road. If you are in a car, the sign does not restrict you, but expect that trucks approaching it will need to turn around or divert. A plaque under the sign may name an exception, such as local deliveries.
The signs it is confused with
Tests pair it with the Truck Route sign, which directs trucks onto the road rather than away from it, and with the yellow Truck Crossing warning diamond, which warns car drivers that trucks enter the road ahead. Red circle and slash always means prohibited.

What does the no trucks sign mean?
Trucks may not use the road ahead. The red circle and slash over the truck symbol is a prohibition, not a warning.
Does the sign apply to pickup trucks?
Each state defines what counts as a truck for this sign, often by weight or number of axles. Where a limit applies, a plaque or the state's law states it; the sign itself carries the national symbol only.
What does a red circle with a slash mean on any sign?
The thing inside the circle is prohibited. The symbol is used across the whole regulatory family, from No Left Turn to No Bicycles.
Why are trucks banned from some roads?
Bridges with weight limits, low overpasses, sharp turns trucks cannot make, and neighborhoods that route through freight around homes. The sign protects both the road and the truck.
How does the no trucks sign appear on the written test?
As a symbol-recognition question, and as a contrast with the Truck Route sign. Knowing that the slash means prohibited answers both.
