No Dangerous Goods Sign
Vehicles carrying dangerous goods are prohibited on the signed route.

What to Do
Use a route permitted for the load being carried.
A Detail to Remember
The diamond identifies dangerous goods. It is unrelated to the white diamond used to mark reserved traffic lanes.
Understanding Prohibitory & Parking Signs
The symbol tells you which activity is restricted. A time plate, arrow or additional message can limit when or where the restriction applies, so read the complete assembly rather than only the red marking.
