Evidence of negative effects of speed cameras

Speed Cameras 'Obsession' Raises Drink-Drive Toll

Axing speed cameras has caused road deaths to FALL

Speed cameras have caused 28,000 accidents in a decade

Senior Sergeant Ian Jones said the driver of the car that hit the van had braked and lost control as he came over a hill. "The vehicle then slid sideways and collided with the rear of the police camera van," he told ABC radio.

The number of accidents has dropped since Bristol speed cameras switched off. The Avon and Somerset safety camera partnership, which ran the cameras, was disbanded last year and the fixed cameras were turned off in March.

The number of road deaths in Northamptonshire fell to an all-time low in 2011, police figures show. The figures, the lowest since records began in 1960, coincided with the year the county's road safety partnership was disbanded and fixed speed cameras were switched off.

Police remove ten speed cameras over safety fears. “We recognise that there is a potential safety hazard from sudden braking if you can’t see the camera”

Speed camera that rakes in £500,000-a-year blamed for doubling of motorway casualties

Dorset Road Safe was made aware of some negative effects in August last year:http://www.thisisdorset.net/news/tidnews/8316512.print/ It said at the time it had “no knowledge of this report” but it most certainly did after this time. “Thirty one per cent of motorists questioned in a poll of 1,532 drivers have witnessed an accident or a near-miss as a result of drivers’ erratic behaviour when faced with a camera with five per cent braking suddenly when a camera come into sight.” 

Motorcyclist killed in A316 speed camera crash

Letter from Transport-watch


One site which has seen accidents increase is the county’s ninth top earning site - the A625 Ecclesall Road South near Ringinglow Road which snapped 2,421 drivers and made £39,480 through fines.

Obstruction due to badly positioned "safety" vans


"Three speed cameras in Preston that pulled in £18,000-worth of fines in 2010 actually bore witness to an increase in the number of accidents since they were installed."

"Not only is it scandalous that cameras where casualties have increased have been kept in operation for many years, it is even more disturbing that the authorities have hidden this data and authorised continued operation whilst being in possession of this knowledge"


A DRIVER may have been killed because he braked suddenly after spotting a speed camera. Police say Graham Davies, 45, is unlikely to have even been speeding when he lost control of his car.

A driver who knocked down a 69-year-old woman could have been distracted by a speed camera, a coroner said.

AN experienced motorcyclist lost his life after braking too hard – almost certainly because he had just spotted a speed camera van at the side of the A338 Spur Road, a Bournemouth inquest has heard.

"A police spokesman said: ‘It appears that he suddenly saw the traffic control measure ahead and lost control as he tried to slow down."


Coroner Sheriff Payne said the evidence suggested that Mr Richardson ‘slowed down for the speed camera, dropped a gear then accelerated quite hard from the speed camera’. (Distraction)

Prof Richard Allsop and, by association, the RAC Foundation, admits that ... In common with many other safety interventions, speed cameras can have unintended consequences and have given rise to some collisions and casualties that would not have occurred if the cameras had not been deployed.

40 negative effects were listed here in 2007:http://www.safespeed.org.uk/sideeffects.pdf

"Speed cameras 'do not cut accidents'... they create them, study finds"
"The MP said he was aware of one camera at Queensway in Hemel Hempstead that had caused rather than prevented accidents."
"The number of collisions recorded at Braintree’s only speed camera have risen since it was put up."

"SOME speed cameras in Dorset have not cut accident rates – and casualties near some cameras could even have increased, according to statistics. Figures show that many cameras have done little or nothing to improve accident rates, but have proved highly effective in clocking up speeding fines. "
New statistics from the Department for Transport have today revealed what has been believed about speed cameras for quite some time. Namely, they regularly fail to cut accident rates and can even increase them.
"Accidents rise despite presence of speed cameras"
"Casualty rates at some speed camera sites have worsened since their installation, figures out today showed."


Prior to 1995 deaths per vehicle-mile were falling at 7% per year.  After that date, instead of accelerating under the impact of the cameras, that beneficial trend collapsed to 2.5%.  Had the previous trend continued there would have been 10,000 fewer deaths that actually occurred.  There is also a remarkable correlation between those extra deaths and the number of fines

(2002) http://news.bbc.co.uk/1/hi/england/2212479.stm
"Speed cameras can cause accidents rather than prevent them, according to research carried out in Leeds. Researchers found seeing a speed camera can distract drivers and cause them to slam on the brakes. Accident rates were studied on two of the main roads in and out of Leeds. In both cases, accidents have increased since cameras were installed."




About average speed cameras:

Prof Allsop's quote can be found in the Q&A download at
This is a bit lengthy, but shows that average speed cameras are little better than fixed or mobile when considering negative effects. 

Average speed cameras (ASC) have been hailed as revolutionary – avoiding the problems of distraction and sudden braking associated with fixed/mobile cameras.  But the Highways Agency's report “Safety Camera Technology at Roadworks – Final Report, March 2008”, concedes that several hazards are created by the deployment of ASCs:

·         Sudden braking

·         Distraction

·         Reduced headway (time between vehicles) - exacerbated by the sudden braking

·         Lane changing

The report also acknowledges that there are no proven safety benefits (collision/casualty reduction) and that driver education campaigns may become of increased importance to encourage “correct behaviour” in the presence of the cameras.

These conclusions are all the more surprising when you realise that the participants in this study were employees of the HA or the consultancy preparing the report (many subjective comments suggest that they are predisposed to the “potential benefits of speed cameras”).

The HA report can be downloaded from


Safety engineering is guided by a number of principles, one of the most important being the order of precedence for methods to address hazards, as follows:

  1. Eliminate the hazard.
  2. Reduce the risk associated with the hazard or accident by implementing engineered mitigation strategies (eg. safety interlocks, such as the safety catch on a gun).
  3. Reduce the risk associated with the hazard or accident by implementing mitigation strategies based on human factors (labelling, training or procedures).

In the case of ASCs, the source of the hazard is clear – it's the introduction of the cameras.  It is no more than wishful thinking that drivers can be educated to deal with that hazard - that is very poor, indeed culpable, safety engineering. 

As there is no safety argument for using the cameras, the first choice is to remove the cause of the hazard (i.e. take away the camera);  increased signage and driver education (as proposed by the report) to mitigate the hazard are covered by number 3 on the list and are therefore much less satisfactory and will never be as beneficial as eliminating the source of the hazard.

A “safety device” that actually reduces road safety until drivers adjust to it is totally alien to all safety thinking and culture.

The HA report was comparing ASCs with fixed cameras, concluding that ASCs had fewer drawbacks.  I have explained above that there is no safety argument for the deployment of ASCs, and it therefore follows that no speed camera should be allowed to be deployed on our roads as it is clearly decreasing road safety.  Mobile cameras are worse than fixed cameras in this respect.


DANGER to speed camera operators:










..And no positive effects?

"SPEED cameras have failed to cut accidents at almost half of all sites where they have been installed in South Yorkshire"

"SPEED cameras installed to stop accidents are not doing their job, according to national figures"

"SPEED cameras in South Bucks are failing to cause accident rates to drop despite successfully bringing average speeds down."

"In Midsomer Norton and Radstock, none of the areas where mobile camera vans operate has seen a significant fall in accidents since their introduction."

"Speed cameras have little or no effect on reducing road accident on roads in the West Midlands, statistics released today suggest."
