If you're caught speeding, you'll be notified through a Notice of Intended Prosecution (NIP) sent to the vehicle's registered keeper within 14 days of the offence. The recipient must confirm the driver's identity, after which a Fixed Penalty Notice (FPN) may be issued, entailing a fine and penalty points on the driver's license. In the UK, drivers have the option to either accept the FPN, contest it in court, or, in some cases, attend a speed awareness course to avoid points. You'll typically know you've been caught if you receive an NIP through the post. Similarly, some speed cameras may flash when capturing an offence, however, immediate indications are not always present, especially with average speed check cameras.
