it wouldn't do much i guess it will lower carbon emissions
They don't ! Maximum speed on a dual carriageway is 60mph - Motorways is 70mph.
The national speed limit for motorways has not changed since 2007 and remains 70mph unless otherwise signed. The restrictions on HGVs changed in April 2115, it used to be 50mph but is now 60mph.
Unless signs say otherwise, there are three speed limits for cars without trailers or caravans;- 30mph where there are streetlights. 60mph on single carriageway roads without streetlights. 70mph on motorways and duel carriageways without streetlights .
It is a measurement of speed.
It depends what kind of road you're on and the vehicle you are driving. Any built-up area (anywhere that has street lighting) is 30mph. Dual carriageways are up to 60mph, while motorways are a maximum of 70mph.
