Bloke at work has just been done speeding in his older merc van. he was doing 50-odd in a 60 limit single carraigeway road. he didn't realise the limits are lower for vans. - here's the deal - if the van is car derived and less than 2000kg loaded then the car speed limits apply - if non car derived or over 2000kg laden - then lower limits apply for single and dual carraigeways.
So here's my point - lots of us run old pickups - where do these fall re speed limits?? My 58 GMC f'rinstance - non car derived - over 2000kg loaded - do I need to stick to 10mph below the national limit on single and dual carraigeways??
