I have recently been flashed by a Gatso camera, what happens next? The Police have 14 days to send you a Notice of Intended Prosecution (NIP). They also get an allowance of a couple of days for the post to deliver it. So if its more than 17days since you were flashed they are too late to prosecute you, unless you were driving a company car, hire car or someone elses car. In these circumstances they are allowed more time to track you down.
