<p>There’s a well-known movie trope in which a hacker takes control of the traffic lights in a city, causing general mayhem or creating a clear getaway path. Unlike many Hollywood representations of hacking, this is actually possible in principle; many cities install Emergency Vehicle Preemption (EVP) systems in their traffic signals to turn them green when an emergency vehicle is approaching. To see what it would actually take to control one of these, [xssfox] <a href="https://sprocketfox.io/xssfox/2026/03/04/strobecom-ii-reverse-engineering_-can-a-flipper-ze/" target="_blank">reverse-engineered a Strobecom II</a> EVP system.</p>
<p>Most EVP systems, particularly older ones, use a strobing infrared light to alert a traffic signal to an approaching emergency vehicle. To avoid misuse, vehicles often encode a vehicle ID in the infrared signal. There have been some claims that a Flipper Zero can trigger these systems, but none that were well-verified, and probably with good reason; anyone actually trying this against a live system is courting serious legal trouble. To see whether this was actually possible [xssfox] obtained real hardwar

This is one of my favourite public light art works, straightforwardly named Traffic Light Tree by Pierre Vivant, in the middle of a roundabout in London. It's a fun but also a tad uncanny combination of flickering city life and, err... nature? And yes, it has confused some people, who thought it was an actual traffic light.

A red traffic light shines behind a glass noise barrier. The glass panels are set in steel posts. The glass is heavily covered with condensation. Images of birds are stuck on the glass. The sky is dark blue - half an hour before sunrise.

The image shows a close-up view of a traffic light against a gray sky. The traffic light is mounted on a vertical pole and consists of three round lights arranged vertically. From top to bottom, the lights are red, yellow, and blue-green. The lights are all illuminated. The traffic light housing is black, with a slightly reflective surface that adds a subtle sheen. The angle of the photograph is slightly upward, capturing the traffic light from below.

This afternoon I was rearended by an inexperienced driver in a hurry; we both survived uninjured, albeit shaken. I saw a few lessons; I welcome additional observations.
The light turned yellow as my Savana approached a major intersection. I stopped and put it in Park. Boomp! I was pushed into the intersection; boomp! pushed further. I was in Park! How come I was rolling? Fortunately, my brakes stopped me. I went back to the Corolla that had hit me. I asked, “Did your brakes go?” She apologized profusely, and said she’d assumed I would roll through the yellow.
I was flabbergasted that my van kept rolling into the intersection. I don’t know whether that’s the nature of automatic transmissions’ Park setting, that once the vehicle is nudged, being in Park doesn’t make it stop—likely--or rather that her car was still pushing my van right in the intersection.
At first I was disturbed that she hit me Boomp; Boomp; then I realized that maybe she rammed me once, and then the air bag affected her control.
I still don’t have her name and insurance info, but when the police report eventually is posted, it should be there, so I can pass it on to my agent.
I applaud her for owning up to the police. I am grateful that her air bag protected her. I’m grateful that I wasn’t driving my wife’s little hybrid. And I learned that yes, a sedan can not only bang up a ¾ ton van but shove it a few car lengths.
