I found an article from Ireland about a safety feature that locks emergency doors when the bus hits a certain speed, then unlocks them when the bus goes below that speed. They implemented this in response to several students who fell or jumped from moving buses, which is a widespread problem in the States too. Have you guys heard of American buses (or any buses) that have a feature like this?

I know FMVSS 217 requires an interlock system, but since it only requires that the bus not START while the doors are locked, I think a feature like this would still comply. I'm just curious if anybody has more information on doors like this, I'd be very interested to see what's out there.

Here's the article for reference:

My guess is that it wouldn’t fly, since the lock could theoretically jam while the bus is moving, preventing exit when it counts.

Plus, I’m sure a lot of other people are like me and see features like that as “just another thing to fix when it breaks.”

Before I started working here, I drank, smoked, and used foul language for no reason at all. But, thanks to my job, I now have a reason.

From NHTSA:

"'Nothing in Standard No. 217 prohibits the installation of locking doors [on a school bus] as long as the vehicle cannot be started with the [emergency] door in the locked position.' In other words, the prohibition in S5.2.3.2 focuses exclusively on whether the vehicle can be started when any emergency exit is locked. If the school bus cannot be started when an emergency exit is locked, the bus complies with S5.2.3.2, even if an emergency exit can be locked once the bus is started."

So it definitely would "fly," I'm just wondering if anyone knows of any bus manufacturers who have actually implemented this feature.

Learned something new. Before this, though, I’ve never heard of such a thing.
