FARMERS can use red diesel in their tractors to help grit and clear snow from public roads during extreme weather, the government has confirmed.

Under normal rules any vehicle used to clear snow from public roads using a snow plough or similar device is entitled to use red diesel.

But only vehicles that are constructed or adapted and used solely for spreading material on roads to deal with frost, ice and snow can undertake gritting work while using red diesel.

HM Revenue and Customs said it recognised the "vital role" played by farmers in helping to keep rural roads and public highways clear.

HMRC officials have recently consulted on a proposed change to the legislation to allow red diesel to be used in tractors while gritting.

A summary of consultation responses will be published shortly.

During periods of extreme weather, HMRC will adopt a pragmatic approach to the rules, it said.

This means tractors clearing snow or gritting to provide access to schools, hospitals, remote dwellings, or communities cut off by ice and snow can continue to use red diesel.

The National Farmers Union said it made "complete sense" to use red diesel cleared for gritting public roads in bad weather.

NFU regulatory affairs adviser Ben Ellis said: "The recognition of the vital work that farmers undertake for local communities in cold weather is a positive step.

"We are pleased that HMRC have taken a sensible approach on this matter.

"Some areas are already receiving the first snowfall this winter while other areas are preparing for what looks to be a cold few weeks ahead."
