I presume buses are exempt from smog checks? I've noticed that their exhaust fumes are disproportionately more obnoxious than that of smaller vehicles.

Another comment asks "I guess we hope these busses will last 35+ years?" so I guess the answer must be "yes" if 35+ year old buses were the norm

Vehicles over 10,000 lbs generally follow an entirely different set of rules, also sometimes qualify for different tax rules.

A smaller vehicle can only transport 4. A bus can transport 30+.

Say each car transports 2 people, it's 15 cars, where their combined emission is less than a single bus.

That doesn't matter for the 30+ people in the school bus inhaling the exhaust. I'm glad I'm no longer in that situation. In my subjective experience, it felt a lot worse than standing near 15 cars. That's what I meant by "disproportionately more obnoxious than that of smaller vehicles"

Genuinely curious if we’ll see any differences in student performance. From my recollection of riding the school bus, those fumes must’ve been knocking a few points off.

At my son's school the leaf blower guy consistently starts work right before student drop off time, ensuring a maximum number of kids (and parents) present to witness the fumes.
