What is STGO – Special Types General Order?
STGO provides a legal framework for moving qualifying abnormal vehicles and indivisible loads beyond normal construction-and-use limits in Great Britain.
Road haulage in Great Britain is governed by operator licensing, roadworthiness, drivers' hours and safe-loading rules. Operators must translate these requirements into documented systems for maintenance, planning, driver control and record keeping.
| Aspect | What to know |
|---|---|
| Core meaning | Great Britain abnormal-load framework |
| Operational use | Categories 1 to 3 |
| Control point | Special speed and weight rules |
| Key caution | Advance notification required |
How does it work in practice?
The operator selects the correct category, displays required markings and gives the prescribed notice to police, highway and bridge authorities.
Before dispatch, the operator checks the vehicle, licence scope, driver entitlement, route, working time and any documents that must travel with the load. Exceptions are recorded and resolved before the vehicle leaves.
Decisions, exceptions and reference numbers should be recorded in the transport order or relevant system. This creates a clear audit trail of the information available and the actions taken by each party.

- Categories 1 to 3
- Special speed and weight rules
- Advance notification required
Always check current contract terms and official guidance as the correct application may vary by vehicle, goods, route, port, customer role or selected customs procedure.
Why does it matter for urgent transport?
Urgency does not override operator licensing, roadworthiness or drivers' hours. Reliable express transport therefore starts with verified capacity, a legal driving plan and a route that the selected vehicle may use.
Good preparation prevents a fast vehicle movement from being delayed by missing documents, unsuitable equipment, incorrect classification or denied access at the collection, border or delivery point.
