Why do busses, trucks have a nearly horizontal steering wheel compared to regular cars?
In: 673
because the steering gearbox is underneath the driver almost vs below from in front of the driver. This is done on larger vehicles to shave inches off the overall length of the vehicle for maneuverability, and on old trucks and busses,overall length was restricted by law,which gave rise to cab over trucks,because making the cab shorter was more profitable than making the trailer shorter and hauling less. Now there is only a restriction on trailer length,but still inches may make the difference in getting in and or out of a place,so inches are still shaved in many ways.
