    Default Dual carriageway speed limit

    On a de-restricted dual carriageway, I take the speed limit to be 70 mph, unless indicated otherwise. Does this only apply where there is a physical separation of the two lanes, or does it apply to all 4-lane roads?

    I know that it's a bit of a retentive question, but I've got a beer-bet on with my mate!

    Highway code definition pasted from
    http://www.direct.gov.uk/en/TravelAn...code/DG_070308

    Dual carriageways
    A dual carriageway is a road which has a central reservation to separate the carriageways.

    Therefore national speed limits is 60mph on multiple lanes with no physical central reservation and 70 mph with a physical one.

    Which is what I thought (that a dual carriageway has a physical separation) - thanks for the link - I couldn't find it in my bleary-eyed state last night!

    Not positive about this, but I think there has to be a sign saying Dual Carriageway for it to count.

    My reason for this is stretch of the A48 near Bridgend that's got the central divider, but is a 60 limit (despite GLF signs). I found out it was a 60 limit when a mate was nicked for doing 75 on it, charged with 75 in a 60, not 75 in a 70.

    Dual carriageway is also a play on words, there doesn't have to be two lanes or more in your direction

    Misunderstanding...

    The dual bit refers to the fact there are two carriageways - ie seperate pieces of tarmac with a central divide carrying traffic. Not the number of LANES in each carriageway.

    Each carriageway may or may not be divided into lanes.

    So a dual carriageway with single lanes marked as a National Speed Limit would have a limit of 70mph?

    Cheers

    As I understand it, if it has the "tuning fork" 'dual carriageway ahead' sign with it. An elongated island wouldn't count.

    Yes - there's one near me with 60mph limit signs (circular with red border - not nsl signs) as you enter it.

    I would have appealed - but as he was doing more than 70 anyway......

    Correct, I learnt that when I did my CPC a few years back. If the speed is posted like the next comment was then it is the speed in the sign ie 60mph if posted as that. There should be a physical barrier.

    He tried it, used the chap who had got me off a couple of NIPs, sadly he'd admitted to riding the bike by the time he got in touch and the rest was just a case of the "limit is 60, you were exceeding it"

    When he first started to argue it he hadn't even read the NIP properly and reckoned he'd been nicked for 75 in a 70, started off with the 10% plus 2 argument, before talking to me and taking legal advice, it went south from there really....

    Some people just seem to attract problems, he's one of them.

    Wow, didn't know that what looks like a dual carriageway might not be one, and that you need to look for the 'tuning fork' or whatever.
