Crash probably a couple seconds later, wouldn't rely on the video for the exact timing.
So it seems that ATC made an error by allowing the truck to cross, and then the order to stop wasn't communicated clearly enough. I wouldn't place much blame on the truck.
Edit: Looking at some other videos with that audio, I'm also not sure if the video I linked represents the time between communications correctly, transmission at 3:15 may have been right after the one at 3:02. Anyway, the best thing is to wait for the investigation.
It was the “truck and company” that was cleared to cross. That’s probably 5+ vehicles you can see following the lead truck that were all approved. All while the jet was on short final. That controller lost situational awareness due to task saturation as a result of emergency aircraft on taxiway parallel to runway 13.
He said "Frontier 4195 stop there please". Then "stop stop stop stop truckon" By the time he clearly tells "truck 1" to stop, they're already entering the runway. Sounds like a bit of confusion.
There is no "the" issue in airline accidents. There are always multiple factors, and all of them had to happen in order for the accident to occur.
Understaffing is absolutely a factor. Had tower and ground not been combined, the erroneous clearance probably wouldn't have been issued.
The ARFF truck not complying with the stop instruction is absolutely a factor. Had they heard and complied, the accident wouldn't have happened.
And there are likely additional factors that will come out in the investigation.
I recommend reading some final aviation accident reports from the NTSB to learn more about how these investigations proceed and what kinds of conclusions and recommendations they include.
Other trucks slow down, but truck 1 does not even try to slow down. I'd also argue that driving so quickly that you cannot maintain control is its own problem. Getting to an emergency 20 seconds later almost never matters as much as arriving safely.
Maybe they were talking about the truck going 24mph, but the plane is clearly going WAY faster than that.
I'm not completely sure but it seems like the runway entry lights are red which very clearly indicates the runway is in use. They should have known better.
Overwork is an issue in general, but I don't know that it was the actual issue here.

It sounds to me like either the Cop or the Firefighter (whichever was driving) wasn't listening to ATC and this whole incident was probably completely avoidable.
EDIT: a video of the crash seems to have warning lights that the emergency vehicle ignored.

One controller working tower duties, ground movement duties, coordinating with other ATC functions off the radio, an active emergency request, and giving clearance amendments all within 2 minutes. It's insane understaffing. On top of it, there was nobody there to take over after the crash. He worked the whole cleanup for the next 30 minutes.
This is an Olympian level elite Air Traffic Controller who was setup to fail.
I've visited towers, center facilities, and have flying (and some instructing) in the San Francisco airspace for 10 years. That kind of failure is systemic way above an individual.
The audio I heard seems to show the firetruck asking if the runway is clear to cross, the controller responding in the affirmative, the firetruck confirming the affirmative, and then 7 seconds later, the controller saying STOP STOP STOP.
I think the gaps between transmissions have been trimmed, too; this isn't matching other versions of the ATC audio, such as [VASAviation's][1].
> The runway entrance lights look red to me which is also a huge warning flag.
IANA-ATC, but presumably in an emergency, you're permitted to obtain clearance from ATC to enter an active runaway, to get to the emergency. (Which they did, and got, but which ATC later effectively revokes with the command to stop, prior to the accident. Whether ATC should have granted the clearance, well, I'll wait for the NTSB report there.)
The syntax of languages like Lisp and Forth are so fundamentally different that they don't need an explicit statement separator. You don't have to think about many other things either, or I should say you don't have to think about them in the same way. Consider how much simpler the order of operations is in those languages.
SIMD workloads on CPU tend to be bursty. If your workload is all SIMD with few other instructions or branches, it's almost certainly going to be faster on a GPU or SME co-processor.
If there's space between the SIMD instructions, then double-pumping or even quad-pumping isn't very expensive (and with 6 SIMD ports, it might even be basically free).
This core was released in the MediaTek 9400 in October 2024 some 16 months ago.
The successor of x925 is C1 Ultra and even that was released 6 months ago in September 2025 with the MediaTek 9500 and GeekerWan even has a phone review they did with that chip last year.
Chips and Cheese covers Apple products in a LOT of their posts.
The real reason is probably because they are supported by patrons and can only get new equipment to review when people donate (either money or sometimes the hardware itself).
If you like what they do (as pretty much the last in-depth hardware reviewers), consider supporting them.
Truck declared it was crossing. ATC told it to stop. Truck didn't stop.
This wasn't a communication issue.
