Beginning in November 2016, all new motorcoaches and some other large buses must be equipped by manufacturers with three-point lap-shoulder belts, the National Highway Traffic Safety Administration said.
Ahh, but there is an exemption
The rule doesn’t apply to school buses or city transit buses.
What do these two exempted categories have in common: They mostly belong to governments (public schools or public transit agencies). So the government comes up with an expensive new regulation, but exempts itself from it, applying it to only private operators (who own a minority of buses in the country).
