Why Is Red Diesel Illegal
Red diesel is also known as gas oil. It is a type of oil that is dyed at production to make it easily distinguishable from regular diesel. The regulations around red diesel are mostly around tax issues. However, it can be used in industries like agriculture and construction. It is priced lower than regular diesel and finds good use in off road vehicles.
Regular diesel and red diesel are primarily different in the taxing. Regular diesel is taxed higher and those sold higher. The revenue from taxes is used to invest in the roads and other infrastructure projects. While red diesels are taxed lower and thus sold for less as a means to incentive industries whose processes rely heavily on diesel as a fuel source.
In the UK using red diesel in vehicles that it isn’t prescribed for is considered fuel tax evasion. It also contributes to the degradation of the environment through emission. This is why in April 2022, the UK passed more strict laws aimed at reducing the use of red diesel. Their main concerns being tax fairness and environmental protection. They sought to encourage industries that have traditionally relied on red diesel to consider cleaner fuel sources.
Is Red Diesel Illegal To Use On Public Roads?
Yes! Using red diesel in regular road vehicles is legal.
The main reasons for the UK government’s ban on red diesel’s road usage are; environmental concerns and prevention of unfair tax advantages in their market.
The government of the UK uses several methods to make sure that red diesel doesn’t find its way into UK streets such as;
- Limiting usage to off road
- Roadside inspections such as fuel sampling to detect fuel types being used
- Government agencies such as His Majesty’s Revenue and Customs sometimes conduct random checks to figure out what vehicles are using
The goal of this strategy is to reduce emission levels, especially in towns and make sure no one is evading taxes on fuel by using red diesel on regular roads.

The rules around red diesel can be confusing—but getting it wrong could cost you thousands. Our free compliance guide walks you through who can use it, where, and when—so you never risk fines or vehicle seizure.
What Happens If You Use Red Diesel For Driving On The Road?
If one uses red diesel on regular roads, they’re liable to fines that go from hundreds of pounds to thousands. Roadside authorities carry out fuel samples to determine if red diesel is used on regular roads. Those who get caught using red diesel can have their cars immediately seized or have fines from hundreds of pounds to thousands of pounds.
First time offenders found using red diesel on regular roads get less stringent penalties than those who are repeat offenders. Repeat offenders can also face criminal charges for using red diesel if there’s prove it was intentional
Who Can Legally Use Red Diesel
There are some industries that are permitted to use red diesel such as;
- Agriculture: In agriculture, tractors and other machinery used in the farms are allowed to use red diesel. These machines are only allowed to operate on the farmland.
- Construction: Equipment that are crucial for carrying out construction work are also allowed to use red diesel, but they can only do so on construction sites. Some of these machines are diggers, excavators, and forklifts.
For a vehicle to be eligible to use red diesel, it has to be necessary for a specific function and it doesn’t have to be used on public roads. For example, tractors that are used for farming activities and used solely on farmland can use red diesel.

Worried About Penalties for Misusing Red Diesel?
Even first-time mistakes can lead to serious consequences like on-the-spot fines or car confiscation. Learn how to protect your business by understanding exactly what HMRC looks for and how inspections work.
When Can Red Diesel Be Used?
Two parameters affect the legal use of red diesel. First, job-specific tasks. Red diesel can be used to operate machines that accomplish job-specific tasks, such as forklifts for heavy lifting in construction.
Also, during some seasons, red diesel is more likely to be used in some industries, like in the agriculture industry during the harvesting season, most machines would use red diesel. However, it’s important for businesses that use red diesel to always remain conscious of the fact that when they switch to some kind of task that involves transporting anything along public roads, they have to use taxed fuel and not red diesel.
Where Can You Use Red Diesel Without Breaking The Law?
Legal use of red diesel is restricted to some specific locations, including;
- Private Land: This includes farms, private construction sites where the fuel is necessary for the operations.
- Farms: In the agricultural industry, red diesel can be used to operate several machines
- Construction sites for machines that perform specific tasks like heavy lifting
It’s important to understand the legal boundaries existing around the use of red diesel. For example, even though red diesel can be used in machines for agricultural purposes, if that same machine were to travel along public roads, using red diesel in it to travel across a public road would be illegal.
Why Was Red Diesel Use Banned For Some Industries And Not Others?
In 2022, the regulation around red diesel changed, leaving only some very crucial industries with the ability to use red diesel. For example, in agriculture, the red diesel was still permitted to be used because of how crucial agriculture is for the population.
Red diesel was also allowed in construction because of how expensive it would be to use taxed fuels in construction. But overall, the goal of the government is to achieve tax fairness, promote sustainable practices, and reduce the overall carbon footprint associated with diesel usage. It’s part of the drive to push a transition towards greener fuel sources.
Why Is Red Diesel Dyed?
The red dye in red diesel is very crucial in aiding law enforcement to identify misused fuel. The dye is not just a marker but it’s made part of the chemical makeup of the fuel and remains in the fuel for an extended period of time, several weeks.
This helps officials to easily identify if there has been use of red diesel on public roads. For example, the presence of dye in a vehicle’s fuel system would be clear proof that red diesel has been used by that car.
Can Anyone Purchase Red Diesel?
Given the regulation around red diesel, not just anyone can get it in order to prevent misuse. In the case of buying Red Diesel, buyers have to declare the intended use and they have to have proof such as documentation showing that they are involved in an activity that permits them to use red diesel.
A license or proof of usage is usually required at points of sale to ensure that only eligible users buy red diesel.
Reselling red diesel is illegal and may expose the reseller to fines and potential criminal charges.

How Do Authorities Detect Red Diesel Misuse?

- Fuel Dip Testing: This method involves taking samples from fuel tanks to identify the presence of red dye.
- Roadside inspection: Law enforcement can collect fuel samples from roads and analyze them to know what is used on the road.
