Deputy Police and Crime Commissioner for Humberside Paul Robinson was stopped by police on the M180 in north Lincolnshire speeding at 90mph.
He was fined £100 and given three penalty points.
Earlier this year he made a public apology saying he had “made a mistake and had learned the lesson” after being spotted using his mobile phone while driving over the Humber Bridge.
Of the most recent offence he said: “On the afternoon of Thursday September 19, I was at work and driving on the M180 in north Lincolnshire when I was stopped by a Humberside Police traffic officer who had registered my speed at 90mph.
“I admitted the offence and he reported me for prosecution. I have now received a fixed penalty notice carrying a £100 fine and three penalty points. I have paid the fine and sent my otherwise clean licence for endorsement.
“This is the second occasion this year when I have committed a driving offence. It is clear to me I need to give greater attention to my driving and the fine and penalty points will serve as a reminder to me that I have broken the law and been punished for it”.
Police and Crime Commissioner Matthew Grove said: “Paul tells me he has admitted the offence and accepts the punishment he has been given. He has told me that he intends to drive with the utmost care in the future.”
Last November 29 Mr Robinson was seen talking on his phone as he approached a toll booth on the Humber Bridge.
The offence was not witnessed by police, but it was reported and he was later given “words of advice”.
At the time he said: “It was dealt with in the correct manner, I didn’t receive any special treatment.
“I basically got a lecture on the dangers of answering the phone. I wouldn’t normally have done it because I’ve got Bluetooth in my own vehicle.”
Mr Robinson’s appointment as deputy nearly a year ago was mired in controversy.
The police and crime panel set up to monitor the commissioner opposed his appointment by eight votes to one but was overruled by Mr Grove.
The appointment drew allegations of “cronyism” as both men had been Conservative councillors on East Riding Council together.
