Got really wound up on the M42 last week, I thought I understood how a 'variable speed limit' was supposed to work: different times of day lead to different traffic conditions so to manage jams they can drop the limit from 70, to 60 or even 50 or 40mph.

What I was not expecting was the seemingly random increases and decreases on a drive along a single 5 mile stretch of road. I had to be bloody careful because despite setting my cruise to the prevailing limit per GPS I felt like I was going to get caught out with the constant increases and decreases and make the appropriate adjustments.

Anyone know if that's how it's supposed to work?

Cheers,

As someone who drove it for the first time (business trip to Birmingham Airport) its bloody dangerous. I spent more time looking at the speedo and the overhead signs than I did watching the road. Terrible idea IMHO.

I don't know if there are any guidelines about the number of limit changes in a given distance, but perhaps there should be.

I drove to Minehead a while back down a A road which suffered a similar problem 30,40,60,40,50,60,40,30 etc etc - like a yo-yo. It doees require concentration that would be better spent watching the road.

Either sit at 10mph below the lowest limit or accidentally snap half your number plate off and sit at 140mph smile

It is stupid, but IME those cameras take some coaxing wink.

I use it quite regularly, so I'm used to it now I suppose. The most puzzling 'advice' I see displayed is "Queue ahead" at 11pm when there's hardly anything about, and of course - not the slightest hint of a queue anywhere. confused

I think I may have got done by these on the M6 the other week.

The normal 40, 60, 40, 50, 60, 40. Was pootling along at 55mph in lane 1 with little traffic for at least 300 yards when I went through a 40. Now I didnt see no flash but it was a bright day, do you think I would have seen it?

I realised my speed just as I went under so I was looking for it. Unfortunately for my conscious I didnt notice if there was actually a camera on the gantry. If there was, then Mr Mk2 FRS that was passing me will also be picking up 3 points.

About as useful as the "Spray Possible" signs... Can't wait for the "No meteorite strikes recorded on this stretch of motorway - yet" sign along with the instant smash hit "You never know, you might cop off with your really sexy neighbour"

Could the road signs be any less helpful these days? Some of them are verging on surreal and trying to wade through some of the forests of signage takes 99% of your concentration...

Previous poster is right though, those variable speed cameras are quite generous. How much are Polish licence plates anyway? biggrin

I wouldn't worry too much tbh. I've seen the ones on the M42 flash a couple of times (on the opposite carriageway ) but I think you've really got to be going a fair bit over the posted limit to provoke them. My colleagues and myself are always up and down that section of the M6 and I've never heard anyone have a bad experience yet (and we like to get where we're going).

Thats comforting, thanks. Though I'd say 15mph over is quite a bit. The thing is its fair game if it was 55mph in 40 by Gatso, but slowing to 40mph on what is a very clear motorway on a lovely spring afternoon just felt so alien, dangerously slow like.

When they were putting the new ones up on the M3 n/b one had the signage (on the matrix) "Sign not in Use"

Huh.

I travel these (M42 and M6) on a regular basis and hate them.

As a purveyor of 6 points myself, I dont take any risks and travel with them even if they are against the flow of traffic. I tend to stick in the inside lane to achieve it even though lorries are up my chuff asking me to speed up while going through a 40, then up to 50, then down to 40.

The ones heading on to teh M6 Toll are the worst as all lanes are subject to the speed limit change but only the 2 inside lanes get snarled up (heading off onto the M42) yet the lanes dedicated for the toll road are clear, yet still require you to go at 40.

BTW only 1 in 3 or so of the gantrys actually have cameras on them, so to the chap who went through a bit over, you should be ok.

Very dangerous IMO

I've said it before, I hate the m42 for these cameras and their constantly changing limits. The only ticket I have had driving in the last 11 years in the uk was 57 when the camera was showing a 50 limit... And the motorway was almost empty rage

What happens here...
The last limit you passed in your lane read 60. What speed limit will it now be based on this?

The above photo is a bit rubbish, but the lane sign is not lit. The three other lanes are 40, 40, and closed (x).


Similar to these photos:
