PSV / Bus & Coach Speed Limits UK: The Full Breakdown
For a bus, coach or minibus (PSV):
Up to 12 metres: 50 mph single carriageway, 60 mph dual carriageway, 70 mph motorway.
Over 12 metres: 50 mph single carriageway, 60 mph dual carriageway, 60 mph motorway.
Only the motorway limit changes with length — single and dual carriageway limits are the same either way. PSVs with more than 8 passenger seats must also have a legally mandated speed limiter capping actual speed at 62 mph. Speed Angel's PSV mode applies the correct limit automatically based on vehicle length.
Bus, coach and minibus speed limits are frequently confused with HGV limits — understandably, since the numbers happen to coincide in England and Wales. But PSV (Public Service Vehicle) is a distinct legal category with its own rules, and the one place it genuinely diverges from HGV is the one drivers are least likely to expect: north of the border in Scotland.
The PSV speed limits in full
These limits apply to buses, coaches and minibuses classified as PSVs, as set out in the Highway Code speed limits table. The only variable is the vehicle's overall length.
| Road type | Up to 12m | Over 12m |
|---|---|---|
| Built-up area (30 mph zone) | 30 mph | 30 mph |
| Single carriageway (NSL) | 50 mph | 50 mph |
| Dual carriageway (NSL) | 60 mph | 60 mph |
| Motorway | 70 mph | 60 mph |
Most single-deck and double-deck buses and coaches fall under 12 metres. Articulated (bendy) buses and some longer specialist coaches exceed 12 metres and lose 10 mph on the motorway as a result — the only road type where length makes a difference.
PSV is not the same as HGV — even where the numbers match
In England and Wales, a PSV under 12 metres (50/60/70 mph) shares its single and dual carriageway numbers with a goods vehicle over 7.5 tonnes, and a PSV over 12 metres (50/60/60 mph) matches the England/Wales HGV table exactly. It is easy to conclude the two categories are simply "the same rules by another name."
⚠️ They are not. HGV and PSV are separate legal categories that happen to produce the same numbers in England and Wales today. In Scotland, HGV limits over 7.5 tonnes are lower on single and dual carriageways (40/50 mph) — but nothing in PSV regulation reduces bus and coach limits the same way. A coach and an HGV crossing into Scotland side by side do not necessarily share a limit any more, even though they did in England moments earlier.
The 62 mph speed limiter law
Separately from the posted road limit, any vehicle adapted to carry more than 8 passengers (9 or more seats) — which covers the overwhelming majority of buses, coaches and full-size minibuses — must by law have a speed limiter fitted, capping actual speed at 62 mph (100 km/h). This has been a legal requirement since 2005 and applies regardless of the posted limit.
This is a different figure from the 56 mph limiter that applies to goods vehicles over 3.5 tonnes — another reason not to treat PSV and HGV rules as interchangeable. A PSV under 12 metres has a legal motorway limit of 70 mph but a physical limiter cap of 62 mph — the vehicle cannot actually reach the posted limit under its own power.
Practical implications for drivers and operators
- Know your vehicle's length, not just its class. The 12-metre threshold is the only variable in the whole table — everything else is fixed regardless of length.
- Don't assume HGV and PSV limits move together across the border. They coincide in England and Wales today, but Scotland's HGV-specific reduction does not carry across to PSV — check both separately if you operate mixed fleets crossing the border.
- The limiter isn't the legal limit. 62 mph is what the vehicle can physically do, not necessarily what the road allows — on a single or dual carriageway, the legal limit (50 or 60 mph) is well below the limiter cap regardless.
Frequently asked questions
-
70 mph if 12 metres or under in length. Over 12 metres, the motorway limit drops to 60 mph. Single carriageway (50 mph) and dual carriageway (60 mph) limits are the same regardless of length.
-
The numbers currently coincide in England and Wales, but they are different legal categories. In Scotland, HGV limits over 7.5 tonnes are lower on single and dual carriageways, while PSV limits are not reduced the same way — so the two can diverge by location.
-
Yes — vehicles with more than 8 passenger seats must by law have a speed limiter capping actual speed at 62 mph, a legal requirement since 2005, regardless of the posted road limit.
-
The vehicle's overall length, end to end. Most standard single-deck and double-deck buses and coaches are under 12 metres. Articulated/bendy buses and some longer specialist coaches exceed it.
-
Generally yes — the same PSV table (50/60/70 mph) typically applies, though exact classification can depend on seating capacity and use. Where the 9-passenger-seat threshold is met, the 62 mph limiter law also applies.
