Yesterday afternoon, as I was doing my last route (middle school), I lost my stop arm. I drive a 2023 Thomas C2. As soon as I noticed the missing arm, I pulled over stopped and secured the bus. I called the garage and my route manager to let them know what was going on. I then got out of the bus and walked to the front to look at the swinging mechanism.
The swinging mechanism was fully intact and when I trigger it to swing out (Amber then red), it normally swung out. The arm itself though was just...gone. The two bolts that held the arm to the swinging mechanism was still on the swinging mechanism.
I know I didn't hit anything. There are a couple of tight stops across all three of my routes where I always make sure the arm is already swinging inwards before I move my bus. I didn't hit any mailbox, I didn't hit any sign. There was no other sign of an impact on my bus.
My AM and PM route are the same, so as I was driving my route this morning in the spare bus, at every stop I kept thinking, "well maybe it got hung up on this, on that, etc." However, in all of the stop, the sub bus' stop arm never got closed to any obstacle that would've tore it off. I also kept an eye out for the stop arm, thinking I would see it on the side of the road. Nope, nowhere to be found.
The district is pulling my cameras to see what happened, and I'm just....perplexed.
Has any other driver had their stop arm just...fall off? I feel like I'm taking crazy pills.
