Having had a drive about in an unfamiiar area at the weekend, I played a very boring game of 'see what speed limits aren't signed properly'. Sad, I know!

I started to wonder how far limits extend in these situations,
......an example..........

30 MPH area - buildings and street lighting which then gives way to basically open countryside, ie no street lights, no buildings, just the odd hedge. However no NSL signs and no 30MPH repeaters.

Saw the same the other way. Open countryside into a built up area with street lights, but with no 30's, and no NSL repeaters.

when te signs are there it's very defined, ie the speed limit starts at the signs. But what when they aren't?

Ignore Funky Teapot, I think the dormouse is stuck in the spout. There is a body of opinion on here that improperly signed speed limits are no limits at all.

Having said that, after some (indeterminate at this time, dvd or someone will undoubtedly supply accurate data) distance into a 'built-up area' a 30 mph restriction will apply.

they are unenforceable

thing is, a built up area with streetlights is a 30 zone, so is enforceable. OR, does a 30 zone need to be completely surrounded with 30MPH signs on every access road?

Presumably down the 'unenforceable' route having just 1 of the signs missing makes the entire area unenforceable, as you may have entered it by this route.

Thing is, if you drive to the shops for instance, you probably won't pass ANY 30MPH signs as there isn't a change in speed limit.

DVD, Von, what's the answer chaps?

Had a nosey around. It seems that a 30MPH limit will exist if there are 2 or more lights that if between 13-20 feet high are less than 50 yards apart, or if above 20 feet high are less than 200 yards apart.

So, you need 2 lampposts at least, no more than 200 yards apart and its a 30 zone, regardless of signing, as long as the street lamps are obvious to the driver.

Presumably the 30MPH zone extends to 200 years either side, until there clearly is'n't a lamppost.

I always wondered that, when you see a lone lamppost on an NSL, if that constituted a 30, but obviously not.

What about when the 30 signs are staggered (i.e. on the left side it is about 100 meters further down the road then on the right side)?

that's OK. But illegal if there are lampposts above 20 feet high and more than 200 yards apart.

Quite what illegal means in this context, I have no idea.
