Sat Nav speeds?

Question

I was on the A14 this week.My sat nav gave the speed limit as 70 mph.But surely its 60 on all A roads.Am I mistaken or is it common for this kind of error?

Answer 1

Depends on whether the stretch of the A14 in question is a dual carriageway. Max speed for dual carriageways is 70mph unless otherwise indicated.

Answer 2

For a standard car without a trailer...

Built up area...30mph

National Speed Limit... 60mph/70mph:

The Nat Speed Limit on a Single carriageway 'A' road is 60mph, on a Motorway it is 70mph, but if the A road is a Dual Carriageway with a central reservation, the speed limit is 70!

Perhaps this section is Dual Carriageway? Otherwise the Sat Nav is wrong!!!

Answer 3

70 on dual carriageways

60 on single carriageways unless it says 50

Answer 4

If it's dual carriageway, the limit is 70 mph unless otherwise indicated.
