The survey shows that there is solid support for the cameras designed to catch drivers who try to avoid detection by fixed cameras.
Last month the Government announced plans to change the law making it illegal to use in-car devices that detect mobile speed cameras.
The plans could be announced as early as autumn 2004 when the Government will introduce a Road Safety Bill in the Queen's Speech.
Mary Williams OBE, chief executive of Brake, says: "Today's survey shows there is huge support for mobile speed cameras as an enforcement tool to catch dangerous drivers who are prepared to break the law and risk lives.
“Local communities live in fear of speeding drivers but cannot get a fixed speed camera until four people have been killed or seriously injured. Mobile cameras are an effective way of reducing speed before it is too late."
A report on the survey’s findings is being forwarded to the Government with recommendations for action by the Department for Transport and the Home Office to tackle speeding drivers.
The statistics in this report are based on a survey of nearly 1,000 drivers and motorbike riders, carried out by Brake's volunteers, from February to April 2004.
