A Suffolk motorist contacted an enforcement agency to help cure his "irrational fear" of speed cameras.
Colin Gant, 41, of Lowestoft, who drives more than 500 miles a week in his job, was forced to take detours to avoid the detection devices.
He then approached Norfolk Safety Camera Partnership for help.
Inspector Marcus Rowe said: "We were more than happy to help by talking him through the process and introducing him to the people who operate it."
Mr Gant's phobia grew despite never having been caught speeding, said Mr Rowe.
"Although there's a lot of information on the internet about speed enforcement, it really helped him to have a personal touch to just explain a bit about the process."
Mr Rowe added: "It's recognised that if you drive past a fixed site camera the average person will probably check their speed to make sure they are doing the appropriate speed.
"Colin's reaction went beyond that and he felt anxiety and stress."
