trucks are restricted to 56 mph,why are buses aloud to travel faster even when they are carring 50+pepole?

Answer 1

The trucks are owned by private fleets, the ECM can be programmed to regulate the speed anywhere the company requests. There is, however, a government mandate in process to require all trucks to be regulated at 68mph. The larger companies (John Christner Trucking, Arrow Trucking, etc.) already regulate theirs around 65 anyway. With the new emission regulations that will go into effect in December 2007, trucks will perform entierely differently than the do now, but we'll have to wait and see.

Answer 2

Trucks pull one, sometimes two, and in some states, three trailers. The speeds are restricted as there is always the fear of a trailer getting loose and taking off on it's own.

Can't happen with a bus.

Answer 3

Trucks, in general, carry a heavier over-all base. This makes them easier to turn over, (they're light in the tail end if nothing is hauled) especially if they're hauling cargo. A bus is long and, despite a possible 50+ passenger carriage, isn't as likely to turn over--hence, the slightly different rules.

Answer 4

trucks are regulated by the company itself for alot of reasons nobody on here knows. How do you know that the buses arent regulated at 60 or maybe 70 for interstate travel?

Answer 5

hmmm... I'm lookiing out my office window at a highway.. .and those trucks are sure going faster than that! They might have restrictions, but they sure don't follow them. Although, I have to admit, I see more and more pulling off for their mandatory rest - I think they're supposed to do that after 10 hours of driving.

Answer 6

Because even a full bus weighs far less than a fully loaded tractor trailer and can still stop in a relatively safe manner in an emergency.

Answer 7

Got a schedule to keep.

Answer 8

Odd, ain't it?
