Identifying Speed limits and understanding they are not a target speed if in a red ring 

A good rule of thumb is NSL. No street lights, national speed limit...unless you're told differently. But as you say, a safe speed can vary tremendously, depending on conditions.

They are a Maximum Permitted Speed. You drive to the road conditions otherwise.

In my 1962 Morris Minor 1000 a speed limit is a challenge.

Another trick is when driving along a faster road ro look jnto a side roads to see what speed limit applies there. Then you are usually in a higher speed limit, otherwise there would be no sign 😅.

There's a 20mph zone near me which has signs when you enter it, but none within the zone.

Can I just double check what is started at 3:15 please? "If there's a crash barrier OR there's grass in the middle...". My understanding is that a dual carriageway's speed limit is 70mph ONLY when there's a solid physical barrier in the middle. If only grass separates the two sides - with no actual crash barrier - then the road is technically not a dual carridgeway, and speed limit is 60mph. This is something I was told during a Speed Awareness Course I attended a little over a year ago.

I love your explanation of the national speed limit sign, the white is a lamppost and the black line going through it means no lampposts, that’s so clever! 🙃 It’s also written in the name, how I like to remember it is like this..national speed limit..nsl..no street lights! 😀 I love how you’ve explained everything in the video, I’d just like to talk about a tip and a trick that I learnt from a driving instructor called Shannon on driving school tv’s channel, it’s called the 6 poles hack, I’ll leave a link to the video if you’re interested in watching it, basically you can use 6 poles to work out the speed limit if you’ve accidentally missed the sign, here is the link to the video:- m.ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-4hxYfi2JiWE.html&pp=ygUMNiBwb2xlcyBoYXhr Remember, most of the time it’s unsafe to be driving at the maximum speed limit, that’s all it is, it’s just the maximum that we can drive if it’s safe to do so, most of the time it’s not safe to drive at the maximum speed limit, you have to drive at what I like to call the safe speed limit, so basically you drive to the conditions of the road, so, for example, slowing down in the rain, slowing down when approaching a corner because you can’t see around the corner and there might be someone walking in the road, and then speeding up on the straight when you can see nice and far into the distance. I’d just like to talk about non-motorway special roads, one of the unusual characteristics of all non-motorway special roads is that they must have their speed limits defined within their statutory instruments and signposted explicitly as the national speed limit only applies to all-purpose roads and motorways.

They apply to cyclists. Obeying signs with a red ring is a MUST, not a maybe

This seems like a lot of words to state the obvious. Furthermore, I don't think this is the main reason why people sometimes drive faster than is safe. In my opinion that has more to do with people's underestimation of how dangerous their behaviour in traffic is.

Thats todays problmen: peopel lookin at t SCREENS , not road. I notice drivers looking at screen by their driving ( positing, reaction to hazards, late braking, late turning), now we even see regualr sat nav drivers DRIVING jnto WRONG SIDE OF DUAL CARRIAGEWAY from a junction.. 😅

So instead of keeping eyes on the road, we should look for small signs that government put to make everyone safer. Got it. I'll see if I have any spare time left between looking at 21" screen in my car, talking to someone and looking for small signs on the road. Let's just hope no pedestrians show up expecting me to notice them in time.
