Norfolk police's clamp-down on drivers leads to more than 100 arrests in July
In total, 119 people were arrested for drink or drug use
Police have made more than 100 arrests in July targeting drivers in Norfolk who were breaking the law.
The month-long initiative involved officers carrying out roadside checks in Norfolk to catch people using their mobile phones, speeding, not wearing their seatbelts or drink or drug driving.
In total: 119 people were arrested for drink or drug use; 86 drivers were caught using their mobile phones; and 39 were not wearing their seat belt.
Norfolk Police said the number of people killed and seriously injured on the county's roads was usually 20% more in July than the average across the year.
The force added this was largely due to people making longer journeys and travelling from outside the area for their holidays.
It said the better weather attracted vulnerable road users running, walking and cycling.
Insp Will Drummond said the campaign "aimed to target all fatal four offences".
"We placed a specific focus on driving whilst under the influence of drink or drugs due to the Euros tournament," he said.
More than 6,200 drivers were caught speeding, three of whom were prosecuted. 193 people attended speed awareness courses and 88 paid fixed penalty notices.
The initiative was run as part of a UK-wide operation organised by the National Police Chiefs' Council.
