This story about someone using a hairdrier as a fake speed camera made me think.
- It's illegal to damage a speed camera.
- It's illegal to put up an unofficial sign warning about speed cameras, or flash your lights to warn others of cameras.
- Is it illegal to set up a pretend speed camera?
Suppose she'd got a bona fide sign or a plausible looking box, and set it up on her own property. Is that allowed?
