Scamera Van on the Clive Sullivan Way in Hull parked on a grass verge on the west bound carriageway front facing east. This is a dual carriageway

Said van was shooting out the back, across the carriageway at traffic east bound.

In order to do this it was having to project accross the traffic heading west.

Firstly is this allowed

secondly is there any risk that traffic heading on the opposite direction will affect its signal?

Also I would like to question how the driver can safely park his vehicle in this position as in order to do so he must perform a U turn facing into traffic!

How do you know he wasn’t simply targeting westbound traffic?

So long as the operator and equipment has clear line of site of the target throughout the measurement period: yes.

Because they always film the front of the car to stop people using the don't know who was driving defence.

But with two lanes of traffic, a central crash barrier it's not really a clear line of sight is it?

is that for living in an empty flat for too long?

sites can be multi-directional and enforcement is permitted in any direction
within the site (with the exception of motorways and dual carriageways
without junctions in the site, where each direction is a separate site).
multiple housings or mobile enforcement points are allowed within the
approved site but a vehicle detected speeding by more than one camera at
a site is to be regarded as a single offence
where multiple housings are used, the number of housings must not exceed
the number approved in the operational case
at fixed camera sites, mobile enforcement may also take place within the site.

Acpo code of practice insist on the camera van being within 10 feet of the carriageway
The hand-held laser will only record the true speed if it is directed along the
path of the target vehicle. The vehicle may be either approaching or receding.
If the laser is positioned at an angle to the path of the target vehicle, the
displayed speed is less than its actual speed. This reduction in speed is
proportional to the cosine of the angle.
The angular effect or cosine error is always in favour of the target vehicle,
whether the device is operated in the horizontal or vertical plane.
When operating hand-held devices from the roadside the operator should be within 10 feet of the edge of the carriageway and beyond the minimum operating range (i.e. 50 feet).
When operating hand-held devices from an overbridge, the operator must
stand where possible over the centre of the carriageway being checked. In
respect of minimum range, the operator must carry out a height check from
the level of operation to the road surface directly below then multiply this by
a factor of ten. This figure becomes the minimum distance for operation.
Health and Safety. Never point a laser speedmeter at a civil or military
aircraft, vessel or armoured vehicle. Many military aircraft, vehicles or
vessels have target acquisition detectors, some of which can initiate
automatic counter measures.

Requirements for The day to day operation of enforcement devices have been laid down in the publication “Roads Policing Enforcement Technology Code of Practice(p67)” issued by ACPO. A copy is on their website: www.acpo.police.uk under policies.

(non day-to-day opperation is defined as sites ie:where street racing is ocuring and covert detection must be recorded in a log)
Section 14.4 of the code of practice requires the operator to act within 10 feet of the carriage way and at a range exceeding 50 feet. It says it is important that the beam is held steady on the target area to avoid any slip factor.

To clear up a bit of confusion: I interpret "the carriageway" to be "the carriageway" you are driving on. not the lane you are driving in.
A duel carriage way is "two carriageways" east bound carriageway and a west bound carriageway.

Compliance with these rules has no bearing on the enforcement of offences detected by the use of safety cameras. Non-compliance with these rules and guidelines by a partnership, or representative of a partnership, does not provide any mitigation of, or defence for, an alleged offence under current UK law committed by a driver or registered keeper.

No it doesn't. There is no text in any document stating that.

The DfT Handbook of Rules and Guidance is the only bible the SCPs need to adhere to 100%

Oh yes there is. pm me and I will e-mail it to you. acpo 2004 version 2.3

It was so good they have hidden it....

are we confusing the issue with hand held devices compared to mounted devices
