Once nitro is exposed to Ultraviolet light and heat for extended periods of time it can become sensitive. Once it is diluted into a 2 stroke mix its pretty safe. Nitro by nature will explode under pressure regardless of wether its become sensitive or not. if you get some nitro on the floor and hit it with a hammer it will explode, if you do it once its mixed it is less likely to explode as readily..BUT ! i strongly advise not to do this under any circumstances, it may result in injury .
Anyway wether the Nitro has an indicatior or not in it its a hazard to transport in its natural state.
Ultraviolet light may degrade nitro, but it does not make it contact sensitive, except if exposed to an alkali, which could be a metal. Nitro will not explode under pressure. In drag racing all nitro is required to contain a yellow indicator that turns purple when the nitro is contact sensitive. Even then it will not explode with a hammer on the bare liquid. I think you are getting this mixed up with nitro glycerin. Do not confuse being a monopropellent with being contact sensitive, they are not the same thing. Nitro is safer to transport than gasoline or methanol, due to its lower vapor pressure.
