50mph Speed Limit

Try St. Vincent in the Carribbean. You thought the rides at Alton Towers were scary!! 23 people in a 17 seat minibus and squealing the rear wheels around haipin bends on a dirt surface (at night). Don't mention the drop off the edge or the oncoming traffic.

Single carriagway 40MPH

Dual Carriagway 50MPH

Motorway 60MPH

E.U. Regs, Trucks are not allowed to be powered beyond 89KPH(56MPH)

Correct me if I'm wrong (and someone will), but my understanding is that the above is the case where the national speed limit applies, ie after you have passed the white circle with diagonal black line.
If the there is a specific marked limit, eg 50mph, then trucks etc are limited to 50, not 40. So changing an A road from the national speed limit to a 50mph limit may (and note I'm saying MAY, not ALWAYS) actually speed up traffic.

Unless a lower speed limit is posted, these are the maximum speeds allowed for a vehicle in excess on 7.5 tonnes GVW. So even if the speed limit on a single carriageway is 50 MPH, then the truck is limited to 40 MPH.

Fair enough, I stand corrected. Don't know where I got it from.

im an hgv driver for morrisons supermarkets and we must stick to the posted speed limits[we have trackers and they know if we,re speeding] in fact they want us to keep to 52mph on motorways and the new trucks that have just come are limited to 52mph!!!!!

When we started getting new Fire Appliances built to the Euro regs, they had to be limited to around 62 mph because if they were driven over this, the computer would register a fault - progress?
Unlimited they would do 90. Thats why you can overtake a newer one on the motorway (post 2003/4 if I recall) when it's going to a shout. Unsurprisingly, the drivers quite like getting an older spare appliance to drive when the new ones are off for a service (Tayside has one of the most modern fleets in the country).
