Ambulances To Jam Car Radios In Sweden
Ambulances in Stockholm are testing a system that interrupts in-car audio systems to warn drivers that they need to get through.
The solution was developed by students at the KTH Royal Institute of Technology in the city.
It broadcasts a voice warning, while a text message also appears in the radio display.
It uses an FM radio signal to jam drivers' speakers and stop music playing.
