Correct me if I am wrong but in this country we have different speed limits for vans and trucks, as opposed to ordinary cars, so on a single carriageway ( two way road ) the limit is 50 MPH, on a dual carriageway two lanes each way it is 60 MPH, and then on a motorway it is 70 MPH. So, to what vehicles do the above limits apply, I am referring to the morphing of cars in to car derived vans ect, also do MPV's and 4x4's come into this, and what is the reasoning behind these limits.
Argue away !!!!
