Well i have to expect that i have probably been caught speeding today.
M20, a really long steep hill and 3/4 of the way down there was a camera van on a bridge. I guess i was doing about 80mph which is silly yes i know but safe in the circumstances.
There were cars passing me 20 seconds earlier doing at least 100 and i was following the general flow of about 80.
So, this will be my first offence and i have to assume that i got my picture taken.
Iv'e had my license for probably over 10 years now so what can i expect?
A letter in a few weeks?
3 points and a fine?
or will i have to go to court?
I'm going to try and not worry about it too much but i feel so stupid now.
Anyway, if nothing happens then this hyperthetical:D incident will have taught me a lesson.
How long do points stay on your license?
Bu&&er!!!!!!!!!:(

80 in a 70 with plenty of traffic? Don't panic yet!!

1st of all your car will most likely have been going slower then the indicated speed. If there was other traffic he may have been busy zapping, or may have been looking at the other carriageway.

I thought I was a dead cert a couple of months ago doing 50+ in a 40 on a quiet single carriageway, and no NIP...

Don't Panic

Seconded. The scam vans limits are "generally" much higher than you think, (I know for a FACT that in some areas in Hertfordshire the limit is generally 41 in a 30, and similar in the higher red ringed zones as well)

Thanks for the positive responses
I am a worryer.
We shall have to wait and see i suppose.
Saying that, there was a merc in front of me doing a similar speed who was just about to pull into the emergency services lane. I had allready seen the van and by that time would have been well into his direct line of sight for the lazer.
The Merc on the other hand had clearly not seen the van untill mid overtake at which time he swerved violently back into lane with brake lights comming on strong!.
It looked like a dangerous manouver and had me wondering at how many accidents are caused in this way.

If your speedo was indicating 80 then the chances are that you were doing 78'ish as generally they run faster that the actual speed.

Conditional offer (3 points/60 notes on a Licence with less than 9 points)kicks in at 79 and above.

From 0001 hours tomorrow (16th) mark forward on your calender 14 days and if you have had no paperwork i.e. NOIP/s 172 form - providing you are the Reg Keeper - then take that frown off the brow. If not the Reg keeper then do the same check with them.

what car were you driving?
Not sure if it varies much in the same manufacture but my 16v Chavalier reports 80MPH Indicated (GPS 71MPH) and my Saab 9000 80MPH Indicated (GPS 78MPH).

GPS and speedos determine velocity in different ways.

A speedo will measure the pulse rate from a sensor on the transmission. The indicated speed from a speedo will usually be precise/repeatable (especially when at a set speed), though not accurate because long term factors will come into play, such as tyre pressure or wear.

GPS systems deduce an accurate velocity by determining a change of actual distance in a given time. However, GPS receivers have a displacement (distance) error of up to 15 meters (so I hear), which is more than significant when deducing speed over short distances. The way around that problem is to set up the GPS to measure the distance of a long run at a constant speed (as indicated by the speedo), say for several miles on a motorway; the displacement error will pale into insignificance if the test is run for 5000 meters. Any device can measure time very accurately, certainly well within 0.1%. The relatively small time and distance errors will result with an accurately determined velocity.

In this way, the speedo error (at that speed, at that time) can also be determined.

Even cheap consumer grade GPS units are very accurate at speed measurements, the majority are better than +-0.5mph.

I think that one may have got me as well yesterday.

I saw it when I was quite far away and braked, but I have no idea how far up the road he was aiming it.

A few moments before that, a TVR went past me doing about a ton I reckon.

Bro and I checked his GPS against the measured miles near our local HQ. GPS was cock on, speedo same as mine about 2% fast.

No idea of GPS make but knowing my elder bruv it will not have been expensive.
