Anybody know what the laws are for transporting extra fuel (specifically diesel) in Gas cans. 20L, Yellow I believe is that standard, But I was wondering if there is a limit on the amount. I have only been able to find new york state law. Which states 4 5 gallon cans is the maximum, but this is gasoline and not diesel. Looking for info on Canada as well as washington state, oregon, california and mexico. It won't be in the vehicle, i'm not going for any darwin awards.
Just thought this infinite pool of wisdom might be able to help with another facet of my trip planning.
