Speed Limiter Removal — Legal Position & Use Cases

Why van and HGV limiters exist, where removal is legal, and how it's done in the ECU.

Speed limiter removal is one of the most-requested van and HGV services — but the legal position is more nuanced than the internet suggests.

Where it's legal

Off-road, export, motorsport, agricultural and private-land vehicles. Removal on those is straightforward.

Where it's NOT legal

Most UK road-registered vans over 3.5t and all HGVs over 7.5t must run a tachograph-tied speed limiter by law. Removing it is a serious DVSA offence.

Sub-3.5t vans don't have a legally-required limiter — manufacturer limits can be raised within insurance constraints, but always declare to your insurer.

How it's done

Modern limiters are software-only in the ECU — no hardware change, fully reversible flash. Older mechanical governors don't apply to anything you'd remap.
