No-through roads BECOMING NSL

[ajuk]

does not mean 60 is either a safe or target speed. It just means no one has ever bothered to set a lower legal speed limit. I suspect No through Road with a NSL are not that rare.

A No through Road will mean the traffic volume is low, and correspondingly the number of crashes are also low.

I've often wondered if there should be a different symbol for rural roads that means the same thing.

My favourite example. You'd be hard pressed to get over 30 from here without divebombing into the sea!

Ireland has one. It's used instead of posting fixed speed limits on borreens and other narrow lanes. Kind of blows the argument for scrapping the NSL sign out of the water because their research showed fixed speed limit signs increased speeds on roads where they didn't want speeds to increase but didn't feel the need for a lower speed limit (e.g. rural lanes signed at 80 km/h).

Given it looks like the European "end of restrictions" sign it suggests our NSL sign remains the correct and appropriate sign for roads not subject to localised speed limits.

Wasn’t there an instance about 10 years ago, possibly longer, where a driver headed at high speed through a fence onto the East Coast main line, it was a relatively short no through road signed at NSL leading to a closed level crossing. Somewhere near York, I think?

That sounds like this accident, though I can't see the NSL signs on StreetView so they've perhaps been removed?

Yes that’s the one I was thinking of, thanks for looking it up. Seems they couldn’t be sure of the reasons (in the absence of the main witness), but it looks like there’s been a few changes to signs since, and an earth berm at the side of the track.

I asked about this before, if it had improved safety, I don't think I got an answer.

The simple answer is it hasn't existed long enough to tell either way!

It’s certainly helped the sign manufacturing industry!

Cynical bit over… at worst it will have had a neutral effect, but in all probability it will have had a positive effect because it can not be misinterpreted as a “safe speed” sign. The statutory limit is still 80km/h on those roads.
