Different speed limits in different directions?

[seanh]

A situation I've been aware of for well over a year. There is a roundabout on a 50 mph limited single carriage way. A road of about a quarter mile length connects this roundabout to another roundabout on a dual carriageway also limited to 50 mph. Going one way (from the dual carriageway roundabout), there is a 30 mph sign as you come off the roundabout. Going the other way there are no speed signs between a repeater 50 mph sign on the single carriageway and the large 50 mph sign on entry to the roundabout of the dual carriageway. So, is it legal to travel at 50 mph going one way along the link road, but only 30 mph in the other direction? Could I be successfully prosecuted for traveling at 50 mph in the direction that doesn't have a 30 mph limit sign?

that's nothing!

where I live we had a road with THREE speed limits.
single carriageway, marked as 40 in one direction, 30 in the other, and as there was no signs indicating otherwise NSL as joined from a side road!

There is nothing wrong with having different limits in different directions on a road.

The OPs question hangs on what the TRO says for the road -
- if there was intended to be a 30 limit on that stretch, but it is improperly signed, then NSL prevails, provided it is not a restricted road.

- if there was intended to be a 50 and it is properly signed, then 50 it is.

- sounds like the 30 in the other direction is intended and properly signed.

There's one like that near here. NSL (70) one direction and 50mph the other.
Guess which side the talivan usually sits?

As far as I can see, there's no real difference between the 2 sides of the road - not that would warrant a 20mph difference in speed limit, anyway.

It's possible that one direction of a dual carriageway could be to a lower standard than the other, due to the difference in curvature or some localised obstruction to visibility.

But since when are speed limits set according to the standard of the road!

so if you're overtaking does the other side limit come into force??
