Police across Thames Valley and Hampshire made 800 arrests during a month-long Christmas drink and drug-driving crackdown, officers have said.
The arrests were made as part of Operation Limit, an annual campaign run by Thames Valley Police and Hampshire Constabulary’s Joint Operations Unit to target motorists driving under the influence of alcohol or drugs.
Between 1 December and 31 December 2025, officers carried out intelligence-led patrols focusing on known hotspots and repeat offenders. Police said improved roadside testing for both alcohol and drugs played a key role in enforcement.
Of the total arrests, 469 were made in the Thames Valley area, with 209 linked to drink-driving and 260 to drug-driving. In Hampshire and the Isle of Wight, officers made 331 arrests, including 146 for drink-driving and 185 for drug-driving.
Police have warned that penalties for driving under the influence can be severe, including driving bans, fines, criminal convictions and, in some cases, imprisonment. Officers said the consequences can extend beyond the driver, affecting families, employment and future prospects.
Detective Chief Inspector Justin Thomas, from the Joint Operations Roads Policing Unit, said it was “disappointing” that some drivers continued to take risks during the festive period.
“We see too often the devastating consequences that can result from this behaviour,” he said. “I am pleased that we have managed to make so many arrests and prevent the potential harm that can be caused by drink and drug drivers.”
He added that police would continue to prioritise road safety and urged members of the public to challenge anyone they believed was about to drive after drinking alcohol or taking drugs.
“Even the smallest amount of alcohol or drugs can impact on your driving,” he said. “It’s not worth the risk.”
