What would staff from HM Revenue and Customs (HMRC) be looking for at a roadside check?

Explanation: HMRC can check the type of fuel you're using, and the type and legality of your load. Red diesel is dyed gas oil with a lower tax than regular diesel. It can only be used in agricultural and construction vehicles (such as tractors). Red diesel mustn't be used in freight transport.
