Speed Warning Device

Or if you happen to live in Bristol or Brighton, some urban roads will be 20 mph. Although if Bristol is anything to go by, (a) there will be a multiplicity of hard-to-ignore signs and road markings making you aware of this fact, and (b) you do what everyone else does, and take no notice and carry on as before.

The A720 Edinburgh bypass is a 70mph Dual Carriageway, for most of its length.

IIRC, it has 70 terminal signs and repeaters, presumably because it has street lighting (and would otherwise be 30mph limit).

So lack of signs would be 30, not "no speed limit", and simple NSL (/) repeaters would be all that'd be needed, not 70.

I'm not entirely sure that he has grasped the principle of national speed limits.

There are lots of places where you just have to know speed limits. For example, you wake up in your hotel in Central London. How long will it be before you pass a speed limit sign? You wake up in your B&B farmhouse in the nether regions of Wales - how long till you see a speed limit sign?

Delimiters are about the courts being able to show there is a clear demarcation of limits so it is a fair prosecution. If a terminal sign is missing, say damaged in an accident and not yet replaced, if there are repeaters, or street lights without repeaters, there is a finite amount of road you can drive along before the courts will determine you have ignored the limit - so pass a couple of repeaters or drive 800 metres through street lights they will deem that the limit by then is established regardless of missing signs.

There is an interesting thing happening on motorway roadworks, where if there are average speed cameras the compliance is almost 100% but there is a stretch near Bristol on the M5 where there are two sets of bridge works and a mile or so between them where they have not released the speed limit for safety. As there are no average speed cameras, there are a lot of people who deliberately drive at 75-80mph, assuming that there is no enforcement, so those of us who abide by the limit are exposed to danger. The speeders would argue that as it is motorway standard without works they are not causing any danger - aside from they are because they have created a significant speed differential with other traffic.

Oddly enough, these speeding drivers are often so paranoid about the ASCs that overall you end up in the same place on the road (they will come screaming in up to the first yellow pole then do 45mph through the roadworks, whereas I arrive at the 50mph limit on 50, stay at 50, passing them through the roadworks, then get left ready for them to come screaming past at the end of the road works.

So often in a later jam you will see the same cars and get that smug satisfied feeling of knowing that you've stuck to the limits and got to the same place at the same time as someone who has risked their licence.

I understand, although don't quote me, but I believe an auto electrician can connect a device to the speed limiter on your car, that way the limiter is set say at 33 in a 30 ? and the other end of the device is connected by a crocodile clip to your left testicle !

Don't ask me for the full diagram, but this is somehow connected to a regulator and when activated, administers a warning which grabs your attention, you can use it at all speeds not just in 30's

I am looking at taking this forward to Dragons Den once I have the Patent, and then rolling it out to all the speed awareness challenged individuals such as the OP

As a piece of market research, do you think this would sell ! or would the magistrates be able to make motorists buy, fit and use this device after their second speeding offence, I think I may have stumbled on a gold mine here ?

Not sure it is the A720, now I've had a quick look on Google. It has 70 terminals, rather than NSL ones, but no repeaters AFAICT.

My Garmin Satnav can give an audible warning if you exceed the speed limit.

Luckily it can be switched off

Was just about to suggest a Garmin.

Like yours mine gives you the speed (presumably a more accurate speed than a speedo) and an alert if you're over the speed limit.

Another thing the O/P might find useful is a car with cruise control. Any time ive had it i set it to 30mph in a 30, 40 in a 40, etc (where conditions permit). Often such systems have speed limiters too that you can set.

Primarily though its about watching your speed via the big dial in front of you, and getting in to the habit of sitting at 30 in a 30, etc - even if that means dropping a gear or two so the car can do so comfortably

It's a great idea but I'm sure there are perverts about that would deliberately speed

I really feel your reply totally misses the point.
Driving is a very complex process and any aids that make it safer should not be discounted.

Continually glancing at the speedo and mentally computing the current speed limit uses up limited mental resources which would be far better used concentrating on everything that is happening on the road around you.

Additionally I do not think it is immoral to drive over the limit but within the prosecution speeds eg 33 in a 30 limit. But would you know the prosecution limit for every speed limit in every police area. I would hope a competent speed warning device would know the difference and could be set to actual limit or prosecution limits.

I would suggest the reason that most people are prosecuted for speeding is because of error and not because they deliberately intended to speed. It's all very well saying people should not make errors, but they do and why not use a device to help us prevent errors.

!!!!!!, you have 6 points on your licence already due to speeding offences, and you still think it's perfectly acceptable to drive at a speed in excess of the speed limit! I hope you lose your licence soon - you are a menace on the roads.

Thanks for all the constructive comments, have started to look on EBay for Garman, also cheap smart phone another option.
With reference to the more critical comments, I have to just take them on the nose, my 6 points are entirely my fault.
Coincidently this morning I was driving in town (at 30 I hope) when a lady driver turned right, straight across my path, I braked hard and stopped a few inches away from her. She was upset and mortified at what she had done. So my observational skills are not completely hopeless and if I had been glancing down at the speedo at that precise moment, we would have made contact.

Also try sitting in a lower gear in 30 limits, it means you have to make a more conscious movement to chance your speed.

This is what I do and if you suddenly spot a speed camera, the engine braking is more likely to reduce your speed faster in a lower gear
