Red Dye Diesel
In short
Red dye diesel is a type of fuel that does not include road tax, traditionally reserved for off-road machinery like tractors. On 5 October 2026, President Trump signed an executive order allowing truckers to use this tax-exempt fuel on highways to lower costs.
In plain words
It is diesel fuel with a red tint so authorities can tell it is tax-free. Usually, you can only use it for farm equipment or construction machines. New rules now allow certain commercial truckers to use it on main roads.
A simple example
A farmer uses red dye diesel in a tractor to avoid paying road tax. Under the new order, a long-haul trucker can also use it to save over £100 per refill.
Why it matters
This move aims to slash fuel expenses for transport businesses and combat rising living costs. It changes long-standing rules about how tax-exempt fuel is used in the country.
Easy to mix up
Do not confuse it with standard clear diesel, which includes taxes to pay for road repairs.
