Speed Limit Signs
Discussion
Afternoon all,
Question about speed limit signs (I guess the clue is in the title)....was driving out of Wisbech over the weekend, going on the A1101 I think between Wisbech and Gote (Tydd Gote maybe??), came across a sign warning of an approaching double bend with a maximum speed limit 40 sign on it. About 30 yards further on was a 50mph speed limit sign and on the bends that the first sign was warning about was also a 50mph sign - which one would you think would be the one that would be enforced? or do you thing the 40mph was just an advisory with 50 being the legal limit?
Don't know if this will work but it was here,

you can see the 50mph sign right behind the 40 on the other side of the road and if you go a bit further another 50 more or less on the bends..

The 40mph limit is advisory
"Advisory speed limits
Advisory speed limits are used on a stretch of road that is potentially hazardous. The location of an advisory maximum speed limit sign varies, but can often be seen on bends. As the advisory speed limit is not contained within a red ring, it is the motorists choice of whether they obey the advised speed limit or not, providing they do not exceed the maximum regulatory speed limit."

Warning sign with an advisory speed speed limit of 40mph due to sharp bends in the road.
I'm sure no-one sees them as a target to be beaten around the bends. Honest. Warning sign with an advisory speed speed limit of 40mph due to sharp bends in the road.

Just be careful if ignoring an advisory limit sign, if you have an incident and speed comes into the investigation, it could be an issue for you.
Have you ever heard of that actually happening?Ham_and_Jam said:

Agreed. Most of the advisories I have seen are on tight slip road bends exiting a motorway, usually an advisory 40; they make sense for an HGV.Warning sign with an advisory speed speed limit of 40mph due to sharp bends in the road.
Red ringed number equals mandatory, anything else, including black ringed numbers, is advisory.

Like these ones leaving the M74 to join the A75. 40 is ridiculously slow for this bend. I've heard it can be taken over double that. Red ringed number equals mandatory, anything else, including black ringed numbers, is advisory.

Follow on question, kind of related…..a fair few of my local roads are undergoing surface dressing which obviously results in 3 inches of loose gravel sitting on top of the roads and skid risk warning signs with a max speed 20mph. The roads are typically NSL roads but obviously wouldn’t be doing that sort of speed with the gravel there which leads on to the question….as well as the advisory 20mph signs (black border) the original speed limit signs have been covered/sprayed over - does that make the advisory 20mph now a legal limit? Probably not a great idea to go much over that while the dressing work is fresh but invariably the signs will probably remain for a week or two before being removed so what happens in the mean time…20 or 60?

Absent street lights they're still a NSL, so 60 carRathcon said:

No. But you know that from what has been said.Just note what the red ringed signs say (or what NSL applies). Remember the red rings/NSL are LIMITS only, drive to the conditions.

It’s just a question, I’m perfectly aware of driving to the limits…..Just note what the red ringed signs say (or what NSL applies). Remember the red rings/NSL are LIMITS only, drive to the conditions.
Which part are you replying No to? And if the speed limit signs have been covered/painted over does that mean they still apply?

That's a confusing one.
Temporary masking has the same legal meaning as removing the sign, or a missing sign - i.e. the limit is generally unenforceable at that location unless signs are not needed by dint of streetlighting (or otherwise) - so if lit, and in the absence of any other regulatory signing, then the road is default 30mph, if not lit the road is default NSL.
The max 20mph on yellow boards will ALWAYS be advisory - it will not have a traffic regulation order associated with it. If it DOES have a TRO (even a temporary), then it will be signed legally with a red circle to be enforcable.

Everyone knows this already, but speeding through surface-dressed areas is a dick move, mainly as it sprays everyone else's car and not just your own.

Thanks for the informed reply, as you say driving at speed through a freshly dressed section is just plain stupid. That's a confusing one.

It was just a question based on the masking of the permanent signs and the presence of only advisory signs, maybe the question took on a bit more of a serious nature when it was moved from GG to SPL.
