Legislation is needed to prevent car park operators "ripping off" motorists, Labour MP has Nick Smith has said.
On 18 September 2012, Mr Smith called on MPs to back his
ten minute rule bill
aiming to regulate signage and ticketing technology for parking charges in public car parks.
MP for Blaenau Gwent said he was worried some operators were benefiting from making car park systems as confusing as possible.
He explained: "It should be simple to get the signs and the pay machines right."
As well as confusing payment systems and signs, Mr Smith said he was "worried about a developing business model" in the industry.
He said: "What can happen is that the land-owner receives the hourly charge from the motorist but the car park operator receives the income from the extra charges.
"So for the car park operator the more confusing it is, the better. When it is confusing for the motorist, the car park operator makes more money.
"That can't be right."
His Regulation of Signage and Ticketing Technology (Publicly-available Car Parks) Bill was given an unopposed first reading, but stands little chance of making further progress without government support.
