Warning signs
Agricultural vehicles likely to be in road ahead
What it means
The "Farm traffic" plate under the tractor triangle: slow, wide agricultural vehicles use or cross this road, often pulling straight out of a field gateway. Expect mud on the road as well. Hang back instead of sitting on a tractor's tail, and only overtake when you can see far enough past it to be sure.
Highway Code Rule 154 — read it on GOV.UK
