Do they detect red lights and stop signs

In many cases, yes. Tesla’s owner materials say its traffic light and stop sign control is designed to recognize and respond to traffic lights and stop signs, using forward-facing cameras and GPS data, and its supervised system is described as slowing down and stopping at traffic lights and stop signs as necessary. 

Waymo has also described how its driver handles dark traffic signals as four-way stops, though it may sometimes seek confirmation checks in unusual conditions. That is a good reminder that even sophisticated systems are designed around caution and edge cases, not perfection. 

So the simple answer is yes, many advanced systems can detect and respond to traffic controls. The more honest answer is that performance depends on the system, the operating conditions, visibility, mapping, and whether the vehicle is being used inside the environment it was designed for. 

Do they detect emergency vehicles

This is one of the most important questions, and the answer is that some advanced systems are specifically designed to do so. Waymo says its vehicles identify emergency vehicles and first responders by detecting features such as sirens and emergency lights, and the company has described using an in-house audio detection system along with cameras, radar, and LiDAR. 

Mercedes-Benz DRIVE PILOT can be deactivated when first responders or law enforcement activate emergency lights and sirens nearby, triggering a takeover request after the system detects the flashing lights and sirens with cameras and interior microphones. Mercedes microphones are included specifically for detecting blue lights and other signals from emergency vehicles. 

I would still be careful about turning that into a blanket statement for every brand or every feature package. Some systems are expressly built for this. Others are more limited.  Consumer vehicles on sale today still require a fully attentive human driver. 

For our stretch of the coast, I think 2026 is more about learning to use advanced driver-assistance wisely than expecting personally owned cars to fully handle every drive from Orange Beach to Pensacola or from Ono Island to Mobile without supervision. That is especially true in areas with sudden congestion, beach traffic, storms, roadwork, and unpredictable local driving patterns. My view there is an inference based on the current deployment limits and supervision rules, not a claim that the Gulf Coast has unique restrictions. 

I do believe we are moving toward a future where cars become better at seeing lane lines, recognizing red lights, responding to traffic, and identifying emergency vehicles. I just also believe that in 2026, the smartest approach is to respect the technology without overestimating it.

Final thoughts from Meredith Folger Amon

If you ask me whether self-driving cars in 2026 use cameras, the answer is yes. If you ask me whether they can detect red lights, in many cases yes. If you ask me whether they can detect emergency vehicles, some of the more advanced systems are specifically designed to do that. The part I would underline, though, is that capability is not the same thing as independence.

Along the Gulf Coast, I think the winning mindset is to welcome innovation, stay informed, and keep a hand on reality. The future is arriving, but in most personally owned vehicles, it still wants you watching the road.
