Ballypete has it, but presented it more politely than I might have done.

I've mentioned before I think about the complete inability to know the speed limit that some (many) drivers demonstrate: the classic case is at a series of three speed cameras on the A505. I can guarantee that at least two days a week, someone will shoot past me at eighty or ninety approaching the first, and then, as I move out to overtake someone doing sixty in the left lane, will see the camera, jam the anchors on, and trickle past the camera at fifty...

"Oh, yeah, a camera. Dunno what the limit is but fifty is probably ok..."

It is a great road for 70mph
Heading away from baldock just after the first speed camera is now known as the roller coaster, although of late I have slowed to 60mph for its as my wife says she feels travel sick at 70mph, were often not even in the Coupe either

That stretch of the A505 between Royston and Baldock (or the A1) seems to confuse everyone. I would love to see figures for the number of drivers caught by each camera...

In seven years' commuting past them on a daily basis, I have *never* seen one of those lights flash...

I love that down-up-down at the first light, but that little hidden right hand bend at the summit is, um, interesting if the road's slippery!

I prefer the Baldock to Buntingford road.

Give me the A939 early on a summer Sunday morning

The same road that I hit 59mph on a bicycle (with some shimmy, just to make it exciting...)

I’m finding 20 zones a pain!
I have a tracker on my company van so am actively trying to adhere to the speed limit but find quite a few newly created 20 zone signage to be very poor!
Some of the signs are right on tee junctions so if you are concentrating manouvrring they are easy to miss as there are no signs until you reach the end!
I also find it wrong that a village with no school can have a 20 zone but a village with a school is still a 30

On the knowing what speed limit you are in without signs, I was in Milton Keynes dual carriageway centre reservation only saw s couple of national speed limit signs but cannot believe it’s a 70 zone I imagine it was 60 but really don’t know
I think signage definitely needs improving

In relation to 'restricted roads' ie 30mph limit, it is the presence of street lighting that is the key. Working street lights up to 200 yards apart usually denotes a 30 limit in a built up area, in the absence of a sign advising of a lower or higher limit. You wont find too many signs at regular intervals because oddly enough it is against the law to have too many repeater limit signs on a road...

The local traffic authority decides on the reduction to 20mph zone after receiving 'permission' from the secretary of state and based on a number of factors rather than a single hazard 'ie a school'. This local arrangement is where the inconsistency probably kicks in so I have some sympathy there.

PS I didn't make the laws, just know a bit about them and common sense doesn't necessarily come into it...

I know a little road that appears almost deliberately confusing...

Start with a downhill single carriageway, with a speed safety camera at the bottom: signed 50mph, with a repeater just before the camera.

A hundred yards past the camera, there's a two hundred yard stretch of dual carriageway (central divider, two lanes each way) with no repeater; ergo, 70mph limit.

At the end of the DC, again no sign as it returns to single carriage; ergo, 60mph limit.

A thousand yards or so later, there's a 50mph repeater - fifty yards before a derestricted sign at a roundabout.

I bet the *intention* is that that road is 50mph all the way... but I'd love to see (somebody else) in court to argue it.

The UK is amazingly inconsistent in its speed limit signage, in spite of all the rules and regulations.
