Hundreds of thousands of motor racing fans are descending on Northamptonshire for the F1 Grand Prix weekend at Silverstone.
Practices get underway today – with qualification tomorrow and the race itself on Sunday.
The event’s the biggest annual policing operation for the county’s force.
Automatic Number Plate Recognition technology will be used once again this year.
Last year’s event saw ANPR lead to disruption of potential criminal offences.
Also officers say if you’re in any doubt over safety or suspicious behaviour – speak to them.
Police will also once again be patrolling the circuit with guns – but they’re reassuring people it’s just a precaution.
