Speed limit dual carriageway question?

[cable tie]

I got done in a van last year and it was a expensive learning curve after many years driving vans i was blind too about this however I had to sell the van merc vito sport because it was a pain in the ar5e driving at 50 single carriageways and 60 on dual carriageways, motorway speed stays the same 70, I was on the A64 near York 9:30am sat morn when they did me, some forces police it and some don't so really depends where you are I was going to contest it as the officer that stopped me did not no a great deal when I asked Q all he did was preach the highway code and show me the vosa sheet.

So this is what I learnt:
If your vehicle panel van has a Leiden weight shown in the v5 more than 2000kg than your restricted.

If the vehicle you have is a van with side window and bench seat factory fit ie vw transporter kombi than its not restricted unless the laiden weight is over 3500kg

Also vosa informed me if the vehicle is based on a car derived van stated in the v5 and/or the laiden as shown in the v5 is less than 2000 kg than its not limited so what I did is buy myself a Astra sportive van laiden weight is 1990 kg and states in the v5 car derived can.

Google it thousands get done by this law there's a web site devoted to it !!
