The nice ones that flash up your speed and say “slow down” when you go through them at 60 plus in a 30 limit, (only joking officer), and say a nice “thank you” when you go through at 28mph.
On the way to Willingham Woods last night I discovered a new one, which seems to be just for the biking fraternity.
It is sited on the A620 between Retford and Gainsborough. This is a road that has been inundated with lamp post messages in recent times, like the one with a three headlight bike, (which appears to be an early RSV), with the comment “To die for ???”, (Well some people do like their Aprilias quite a lot ??!!??)., and the classic "Bends Dead Ahead".
On the bit of the A620 between Clarborough and Beckingham at North Wheatley, there is a dual carriageway with a fast L/Hand bend at the end where it goes back to a single carriageway again, or the reverse coming the other way, which is at the end of a long straight and even faster.
It all used to be unrestricted, but like many roads in this area recently now has a blanket 50 limit, which is not that well respected by any road users.
As I went down the last bit of the dual carriageway approaching this fast left hander last night, at probably about 65 (ish), I noticed the new sign, didn’t get a right good look, but the display indicated a left hand bend, and an LED impression of a bike, the rider has it banked over with his left knee down and underneath in big letters it just says “TOO FAST”.
Quite pretty really, but can’t help wondering does this just trigger for bikes in some way, or does it sense and display something different for the fast white van man with the tail out on opposite lock, or the Rep in his repmobile late for his appointment and explaining the the customer on the phone, whilst taking bend at 90 and drinking a coffee at the same time.
Or alternatively, does whatever goes through it at speed always get a display of a biker getting his knee down?
Keep an eye out for them, you can bet they will be appearing on a fast A Road bend near you very soon!
The left hand bend at the end of wheatly bypass many moons ago, another biker took the bend too fast and hit a lorry head on has he went too wide. unfortunatly there are some that do not know the road and though i do admit it is an awsome stretch to open the bike up it has caught a few out. I do about 2000 miles a month in my van and i see a lot of stupidity with impatient car drivers and van drivers alike, and i travel to the colwick part of nottingham, i use the A 6097 and the a A 614 respectively and in the last few months they have also been turned into 50MPH limits. I travel between 50-60 and even though i am above the limit at times the best way to describe it is has a rat race with cars and vans breaking there neck to pass me, though i do usually catch them up has they get stuck behind lorrys further down
