    Last October following heavy rain a small stretch of the M6 southbound between J28 and J27 was flooded for part of the day. Sure enough, the RTTI identified it and sought to divert me around it. All useful, all good, as it should be.

    But then, the next day, with the flood gone, it still showed that the flood was there (it wasn't) and once again advised me I need to divert around it. Over 3 months later and the RTTI still thinks there’s a flood there and wants to divert me. I travel that stretch most days and to my knowledge the last time it was flooded there was October. So why’s it not worked this out? I had understood the “RT” in RTTI stood for “real time”, which evidently this is not.

    I updated the maps wondering if this might encourage the RTTI to reset itself but it didn’t.

    Then, earlier this week, a lorry shed its load on the M6 southbound between J27 and J26. Sure enough, RTTI told me of this and put up a message in the instrument cluster saying “hazardous traffic situation” or similar. The next day, and indeed, every day since, RTTI still believes the lorry is there and its load is still strewn over the southbound carriageway.

    So now, every day, I get the flood warning from J28 – 27 and the shed load warning J27 – 26. All the other RTTI info, like delays, minutes added to journey, the colouring of the roads according to traffic density, etc. update as they should.

    Anyone else experienced this? And if so, have you been able to fix it? TIA!

    Isn't this the fault of whatever agency transmits details of road hazards, generally Traffic Message Channel (TMC). run by Trafficmaster? RTTI downloads these hazard warnings and if they aren't deleted by the source then they will continue to be shown by RTTI.

    I have had similar experiences unfortunately and this included an extra 1hr on a journey around a hazard that wasn't there anymore! Begining to think that RTTI is worth the money anymore, I get better updates on the tom tom app with live traffic on my iphone + its a lot cheaper and includes speed camera's

    My older system has a simile issue, the grey arrows indicating traffic have been on the map at the bottom of my road for two weeks. No traffic at all there since the road works moved.
    Think mine works off the old RDS system.
