About Traffic Lights: Do they all have secret hidden cameras?

Joe Marler's Things People Do · 2025-05-01

There are some big questions asked in this episode. Do traffic lights actually turn green if you flash at them? Are they all secretly harbouring hidden cameras? And is there one giant control room that turns all the lights red? Today we're joined by Sam, who is a traffic light engineer, and is here to confirm or deny all the myths about them. We all experience traffic lights on a day to day basis... but how often are we actually sat on red? You're about to find out.

Joe Marler's Things People Do

Joe Marler used to hate people, but then he met Tom Fordyce, and a load of ordinary people doing extraordinary things, and a podcast was born that changed his mind forever. It might just change your life too.

Because everyone is interesting if you ask the right questions. And this is a show about all the weird and wonderful things people do.

Together, Joe and Tom meet astronauts, teachers, marine biologists, cheesemakers, prison guards and everyone in between. Along the way, they’ve learned things that have blown their minds, heard stories that have made them laugh until it hurts, and – well, felt a whole lot better about the world around them and the people that fill it.
