Part of West Norfolk was a speeding hot-spot in a crackdown by police.
Community speedwatch teams were out across Norfolk and Suffolk to help educate drivers about keeping their speeds safe during a day-long campaign.
King’s Lynn came top of the figures with 145 offences recorded.
Each of the drivers caught speeding will have their registration number recorded and they will receive a warning letter telling them to keep their speed down.
Community Safety Sgt Sam Burton said: “This action day was a fantastic opportunity for all of the speed watch groups to work in unison at reducing speeding drivers in Norfolk and Suffolk.
“We are always looking for new volunteers to join community speed watch. Community speed watch relies on volunteers who are willing to give up their time and take part in organising and running speed watch activities in their local area.
