Farmers exception fertilizer placard class 5 trick testing apps checks
Many fertilizers, such as ammonium nitrate, are oxidizers, Division 5.1, which uses a yellow placard with a flame over a circle. Certain agricultural operations have limited exceptions from some hazmat rules when farmers move ag products locally, but the material is still hazardous. Confirm the exact exception in the regulations.
Fertilizer is often a Class 5.1 oxidizer
Ammonium nitrate and several other fertilizers are oxidizers: they do not burn on their own but they feed and intensify fire, which is why they are Division 5.1. The placard is yellow with a flame-over-a-circle symbol and a 5.1. That oxidizing behavior is also why fertilizer storage and transport are taken seriously.
The agricultural exception, in plain terms
There are limited exceptions in the rules for certain farm operations, for example a farmer moving ag products a short distance, that can reduce some hazmat requirements. These exceptions are narrow, depend on distance, quantity, and who is driving, and they do not make the material non-hazardous.

Do not guess the exception
Whether an exception applies depends on the specific material, the quantity, the distance, and the operation, and getting it wrong carries real risk. This site is an independent study tool and does not give regulatory advice, so confirm the exact rule with the current regulations, your state, and any agricultural guidance that applies.
