Speed limit signs
Maximum speed limit of 40 miles per hour
What it means
Forty is the legal maximum here and you MUST NOT exceed it. You will usually meet a 40 on a busier road leaving a town, or on a ring road that still has junctions, side turnings and people crossing. Build up to it smoothly, and drop below it if the road narrows or your view closes in.
Highway Code Rule 124 — read it on GOV.UK
