Doctor of Philosophy, Mr Faulkner, 64, was incensed when stopped by police in Leeds who accused him of speeding.
His Vauxhall Vectra was clocked by a laser gun at 43mph in what police claimed was a 30 zone close to the village of Scarcroft.
Convinced that stretch of the A58 Wetherby Road should carry a 50mph limit, he set about a campaign which has forced West Yorkshire Police into a climbdown.
The grandfather used simple logic to show that the three-mile stretch of highway not only baffles road users as to what the speed limit is, but is littered with confusing information which creates unsafe distractions.
The six month battle ended in victory after West Yorkshire Police declined to offer any evidence against him when he appeared before magistrates in Leeds.
Appalled
Mr Faulkner, from Cheshire, was also awarded court costs for his inconvenience.
The retired computer engineer told the YEP: "There is no way they could have made their case stand up in court. I am absolutely appalled that I have been put through this. The speed limit is not 30mph at the place where the police made their laser check. I do not dispute the speed recorded on the police apparatus, but simply state that it is not relevant.
"The day before this incident, I was awarded a degree of Doctor of Philosophy by the University of Huddersfield. My driving philosophy is to drive carefully and try to obey speed limits."
Mr Faulkner took a series of pictures along the road revealing constant changes of speed limit as well as ambiguous signs.
Mr Faulkner also said several signs had no legal force because they had a yellow background.
"Page 73 of the Highway Code shows various traffic signs, with the maximum speed sign illustrates for 40mph. This clearly shows black numbers inside a red circle. The 30 and 50 signs in my photographs are not legal signs."
Mr Faulkner, who was on his way to York when he was stopped, said: "Because I saw one of the police officers grinning when I passed their car, I assume that they regarded the exercise as a game or as a joke, rather than as evidence of a serious offence.
"One of the officers said that they never catch local drivers, who are aware of the speed trap. This behaviour appears to me to come close to entrapment."
The retired computer engineer has now written to West Yorkshire Chief Constable Colin Cramphorn demanding an apology.
He added: "It is clear today that when driving on A-roads in Britain today, the motorist is confused by the proliferation of speed signs, by the absence of repeater signs, and by the frequent change in speed limit."
A spokesman for West Yorkshire Police said: "After the ticket was contested officers investigated further. This revealed that the sign did not meet the requirements of an enforceable speed limit and therefore no further action was taken.
"However, police do have a duty to uphold speed limits and reduce casualties. The action in this instance was therefore considered both proportionate and necessary."
