@ ... It's just untaxed and dyed red to distinguish it for off-road use only, such as for tractors or industrial purposes. ...

Yup.

And now it can be purchased and used by on-road vehicles.

imo, a good [temporary] step towards the relief of the diesel-based truckers in the Country. And I hope this helps them to stay afloat.

But a much better step might be for Pres Trump to end his failed war of choice against Iran.

@#2 ... Why not just take the tax off of all of it? ...

That's what he just did, in effect.

But to your question, because the money from the tax is supposedly used for road and infrastructure improvement.

Similar to the gas taxes.

@#4 ... Only about a third of it is dyed now. Are they going to dye all of it? ...

Only a third now because that was the current demand.

But with this new exemption, how might that demand increase?

@#5 ... Diesel has been dropping for the last two weeks in the Phoenix area. ...

How much has it been dropping?

Please be specific.

thx.

@#8 ... The cognitive disconnect of some is disconcerting. ...

The cognitive disconnect between what Pres Trump is doing, and what he has criticized prior Presidents for doing is not insignificant.

@#9 ... How might the price? ...

Good question.

With the now larger demand for the same level of supply, how might the price be affected?
