average speed cameras

[flitty]

It was on tv recently that if your in those average speed areas if you change lanes a lot then it wont register you. Is that true.

[bednobs]

i can't see how - each lane is monitored

[chrissa1]

I thought there were cameras over every lane to cover this.

check if the lense is actually in the square bit as you drive past, very often it isn't

[wardlaw]

On a single carriageway trunk road you can drive on the wrong side of the road (assuming it's clear) to avoid detection but why not just stick to the speed limit instead?

[chrissa1]

And then crash into the hedge as you do dotty. :/

lol it's kinda obvious to spot but you have a point. lol

The following confirms that you can change lanes and will still be caught.
SPECS cameras operate as sets of two or more cameras installed along a fixed route that can be from 200 metres (660 feet) to 10 kilometres (6.2 mi) in length.[1] They work by using an automatic number plate recognition (ANPR) system to record a vehicle's front number plate at each fixed camera site. As the distance is known between these sites, the average speed can be calculated by dividing this by the time taken to travel between two points.[2] The cameras use infrared photography, allowing them to operate both day and night.

There is a popular misconception that the Home Office has approved the SPECS system for single-lane use only. According to this theory, a motorist can therefore switch lanes between cameras and claim non-approval to avoid prosecution for speeding.[3] However the marketing director of the manufacturer, Speedcheck Services Ltd, has stated that this theory is "categorically untrue":[4]
“ Until recently, the only HOTA available applied to cars maintaining their lanes. However a new test schedule was carried out last year, which means that average speed checking can be applied even where cars change lanes. ”

"Phew" ubasses.

I've been through them at 65 and 70/75 in other people's cars in a 50 limit. They've never had a ticket.

The cameras in the average speed area near me cover all 3 lanes with one camera so changing lanes will not make a difference.

Also bear in mind that the average speed cameras are usually miles apart and that in the distance between cameras you will probably change lanes many times during normal driving.

[EDDIE51]

These camera log your car when it enters the average speed area and again when it leaves so changing lanes will have no effect. It is just a simple calculation if you leave the area too early to have been sticking to the speed limit you get a ticket, simple.

Eddie51 is quite correct and having had some experience of this I confirm some of what has been said, your number plate is noted by the camera as you enter the zone and as you leave your average speed is automatically calculated, if your average speed is above the limit set by the authorities the registered owner of the vehicle will probably receive a fixed penalty notice. If this is ignored the Police will probably issue a summons requiring court appearance, if the driver disputes that an offence was committed they should request a court hearing.
