Speed Cameras on M1

[Dave-exfairy]

Yes they do have discretion - they discern easily between the maximum speed of a car on one piece of road and do not apply that to the heavy vehicles on the same piece. How many heavy vehicles regularly break the speed limit? When was the last time one was caught by a camera? (When was the last time a speeding heavy vehicle was ever stopped - ever?)

Precisely. It is simply the path of least resistence to let them go as fast as they want, under 60, and keep all the traffic moving freely - just as the path of easiest revenue is to take the man out of the linkage and apply a machine to the job.

It's inarguably right (and especially in built up areas), but please don't pretend it is not without another agenda......no-one is that stupid.

Cameras do not have disgression, you're either breaking the speed limit and get snapped, or you're below the spped limit and don't get snapped.
Many HGV's have limiters in them now, oh and the last time a sppeding HGV was stopped? Sometime last week doing 42 in a 30, so ram that one up yer hoop!
Don't have a go at me, I don't work on cameras!

Are the cameras used for flow control or average speed over distance in a network as promised by the last guberment?

Dave is correct in that ALL HGV's are now restricted to 100 kph or 56mph.
Most vehicle speedo's have an error limitation below what the speedo indicates. If the speedo shows 60mph you are probably only doing 57mph.
A HGV which is restricted to 56mph would probably only actually run at 54mph, therefore going through a 50mph speed camera it would be very difficult to get a conviction at 4mph over the speed limit.

If I remember right the cameras from J25 up to 31 (I think ) are gonna be used to enforce variable speed limits as per the M25. I can't wait! DT_Xtremez_34:

I was more referring to just about every HGV on this island which does 50 or even 60 Mph in a 40 limit (the national speed limit for HGVs on a normal single carriageway road).

How often have they ever been stopped? Would it be a good idea? Probably not, but one could similarly argue that a car transitting the same road at 10-20Mph over its speed limit should be afforded the same latitude, by the same logic applied to the HGVs transgression.

Seems to work on the M42 at peak times. Trouble is it's Relatively quiet on the M1 where the cameras are now it's 4 lanes. Leading up to the cameras is a nightmare on a Friday

Dave is correct in that ALL HGV's are now restricted to 100 kph or 56mph.

When they leave the factory, then that may be so - but just like the electronic speed limiters on cars, HGV speed limiters are fairly easy, and very common to defeat or disable. Anyone whos ever driven in Europe recently will have witnessed even nigh-on brand new trucks substancially exceeding 100kmh.

Most vehicle speedo's have an error limitation below what the speedo indicates. If the speedo shows 60mph you are probably only doing 57mph.

To quote the detail of the European Type Approval law, a speedometer must never under-read, but may over-read by upto 10% of the actual speed. So, in the worst case scenario, if your speedo is showing 60mph, you may actually only be doing 54mph - or you may indeed actually be doing 60mph. A GPS speedo is far more accurate than any car/truck speedo - and even more accurate than so-called Police 'calibrated speedometers' (within their accepted limitations).

A HGV which is restricted to 56mph would probably only actually run at 54mph, therefore going through a 50mph speed camera it would be very difficult to get a conviction at 4mph over the speed limit.

Fair comment for when trucks are in NSL zones - but its when they do 50-odd mph in 30 or 40 limits - and that is increadibly common. The reason that not many HGVs get caught (and similarly how taxis avoid it) is simple - CB radios.

The M1 cameras are now live.

I also heard the police have bought up the speed cameras in Oxfordshire and switched them back on again because they weren't making enough money from speed awareness courses

The M1 cameras are now live./QUOTE]

When did that happen? They weren't live this morning and some still haven't been fitted at least between 25 & 26.

 

[Max Reheat]

Well the camera not in use signs have been removed from a couple of weeks ago

 

[burglar]

Noticed the signs between 25 & 26 have gone from this morning and cameras are fitted to every other gantry. So I guess you're right Max the dreaded day is upon us! Tho it hasn't made any difference and no flashes either!
