Traffic Master clock on ebay

[Maxxed_Ross]

you know those sensors that you see hanging from motorway bridges? And sometimes on blue poles at the sides of the road? They send traffic info from the surrounding area to the clock each time you pass one. If there is a hold up ahead it warns you of how far away and *I think* how bad it is on the display

Very low-tech, but quite handy I think

i have got one & it works really well
lets you know about traffic jam way ahead of you
