Bad news for drivers in Norfolk, UK: if you use a laser jamming device to evade hand-held speed guns you may receive a thirty day driving ban.
In a landmark court decision, a 21yo man had his driver's license suspended after he admitted to willfully obstructing a police officer by fitting laser jamming equipment to his Vauxhall Astra. The man was also fined £100 (US$157) and had the offending equipment confiscated by Norfolk Police.
