70Mph Camera Flashed Me Going 77Mph, Will I Get A Speeding Ticket?

[Noobie2024]

A 70mph camera flashed me going 77mph, will I get a speeding ticket? I was traveling down the motorway and a camera double flashed me as I went past. I looked at my GPS (Google Maps) and it said I was doing 77mph at the time. I had not realised I was going that fast and slowed down. It was on the M6, near Coventry, which I believe falls under Warwickshire. Warwickshire Police state that they follow the NPCC guidelines on speeding and allow 10% +2mph. Thus meaning the lower threshold for activation of the camera and receiving a notice should be 79mph. Is this the case? Will I be receiving a notice, even if I was within their own limit threshold?

It depends what the camera (not your GPS) registered.

[Noobie2024]

I understand, but my GPS has always shown the same speed as the speed indicators that state your speed, which you usually see as you enter 30 mph zones. This makes me feel like that is an accurate (as accurate as an app can get) measurement of my actual true speed. If the camera registered that my speed was higher than it actually was and thus at or above the 79 mph NPCC guideline limit, would I have a case against the speeding ticket if I were to receive one?

unlikely, since  the speed limit was 70, everyone's calibrations would have to be seriously out of whack if that was how slow you were really going. Best pin your hopes on the cops going by their own rules and not bothering with you at all.

They have to issue you with a ticket within 3 weeks of the camera flashing, otherwise it gets thrown out. 

 

It will be a nail biting 3 weeks as the fact it flashed is it means its registered a vehicle exceeding the speed limit. 

 

Fingers crossed nothing comes of it.

They have to issue you with a NIP ( notice of intention to prosecute) within 14 days.

If the ticket was issued – written up, created – outside of 14 days after the speeding incident, then there may be a possibility the ticket could be time barred (cancelled). However, there's no guarantee, and by contesting the ticket, you could end up with a bigger fine and more points.

I've had cameras flash me on a motorway when I was blatantly under the limit, yet despite the period of concern afterwards nothing arrived or came of it. Since you are aware you were a bit over, no one can tell you for sure. "Maybe" is likely the best answer. You'll just have to wait and see; try not to think about it, as it's out of your hands anyway.

“If the camera registered that my speed was higher than it actually was and thus at or above the 79 mph NPCC guideline limit, would I have a case against the speeding ticket if I were to receive one?”

The police would produce evidence to show that your speed was measured by an approved device. You would have to cast sufficient doubt on that evidence so that it cannot be relied upon.

“They have to issue you with a ticket within 3 weeks of the camera flashing, otherwise it gets thrown out.”

"They have to issue you with a NIP ( notice of intention to prosecute) within 14 days."

Bearing in mind they do not know who was driving, they have to serve the Registered Keeper (RK) with a “Notice of Intended Prosecution” (NIP) within 14 days of the date of the offence. If they don’t, it doesn’t  get thrown out but the driver can challenge the charge in court (where it will fall to him to prove that no such notice was served in time). No other NIP to anybody else is required by law, though they are normally sent as a courtesy to any people subsequently named by the RK

Although in general GPS vehicle speed indications are quite accurate, better than the vehicle speedometer which must read high by law – there is an inherent error in the way they determine speed, based on the distance travelled across the surface of the globe.

 

When travelling up or down hill, GPS speed readings will be in error in that the speed is based on the assumption that the surface of the earth is flat (no hills).

 

As an extreme example, a vehicle travelling at 100mph down a 45 degree slope will be registered by GPS as 71mph.

[Hymie]

You can observe the above effect for yourself if when motorway driving you set the cruise control to 70mph, where a GPS device will be displaying circa 66mph (a more accurate actual speed).

When the vehicle encounters an incline/decline, the vehicle cruise control will continue to maintain an indicated road speed of 70mph, whereas the indicated GPS speed will decrease by 2-3mph (depending on the steepness of the hill) for the above reason.

[CrapatCryptics2]

If you have a problem holding the correct speed use the cruise control, most modern cars have one.

[ToraToraTora]

I'd say you are probably in the clear, the camera will be set at 79 and if your speedo is working correctly it should over read anyway so I'd say you were probably doing about 73mph so you'll be fine. Let us know if you get an NIP.

[THECORBYLOON]

If the speed camera is set to trigger at 79mphand it flashed, why would the car have been going at 73mph?

[ToraToraTora]

noobie, are you sure it was a 70 limit? I just realised from your OP that it flashed. There are areas on the M6 that are not 70 especially if there are road works or variable limits etc.
