mtbcDriving in England, I often see
Driving the moving van, I became more aware of those defaults because the limits for such vans are different. It was but a modestly sized van but still limited to 60mph on dual carriageways. I got to thinking of the larger lorries that even on motorways are limited to 60mph and wondered about signing I had seen on Scottish sections of motorway that bear a 70mph sign instead of a national speed limit sign.
What on Earth do those mean? Are there any 70mph signs in England too? Can a large articulated lorry really travel at 70mph on these roads? If not, where is the section of the Highway Code that tells me that?
national speed limitsigns which implicitly specify a speed limit that depends on the road one's on and the vehicle one's driving on it. There are also speed limit signs stating a specific number, often 30 or 40, which I believe limit all vehicles identically, at least the Highway Code doesn't seem to add any obvious caveats suggesting otherwise. These signs seem agreeably easy to interpret: one is ordered to apply either the defaults or the given number.
