Maximum speed 105 Km/H on old used trucks? (pg. 2)

another stupid law. Many truck companies enforce 55 mph limits on their trucks to save fuel and mileage costs. However they enforce this by GPS, not governers. Why? Because they still allow for the trucker to speed up when necissary to avoid a hazardous situation.
105 km/h limiters are actually a detriment to safety. Lets hope this stupid law does NOT pass. Perhaps they should put more MTO officers out on the highway to enforce the speed limit if they really want to.
First trucks, then cars...if the government can get away with this, they will try to expand it... trust me on this. |

Actually, most trucking companies use governers... normally set to 65 mph. GPS is used to track the movements of the fleet but it is no good for controling speed as it would require constant requests for locations... more requests equals more cost. Like I said earlier, most US jurisdictions already mandate goveners and most Ontario firms already use them as they are required to operate in those US jurisdictions that mandate them. |

huh?
the gps system at my work is completely automatic and every vehichle shows where it is/what speed and logs everything automatically.
extremley cost effective and specific........ you can even type in .....steeles ave + 85 km/h and it will show u the five buses that hit that speed in the last month. (were governed at 109) which sucks sometimes when you get jammed and could use the extra power to get out of a situation. i agree that the governer does create a safety issue. But probley eliminates a lot more safety issue than it creates. |

Really? You Go people have the best stuff. Most of the trucking companies I deal with need to make specific requests on each unit they are tracking when they want to determine location/speed. Perhaps, the trucking firms just cheap out or the larger required coverage area necessitates a different system. |

unless it has changed then it was always the GPS that tracked where they were, how fast they were going, idling etc.
When i was travelling with my uncle 10 years ago this is how it was with schneider. They had a limit of 55 mph governed by the GPS system. |

| hahah we barely drive over 40 sometimes in our work trucks only cuz we like to take our time to get places.. |

I totally forgot about that. With the size of the front of a truck, that would be alot of drag.
But, do frictional forces increase in the same way, and would the play a large factor here? If the truck face was frictionless, would it still create drag? |

Drag = friction. It is impossible to create a truck or should I say any object that moves through a medium with zero friction. Theoretically the only way you can move an object with zero friction is if you move it in a vacuum (the closet approximation being outer space). |

int he 70s the US used the same arguements of fuel economy as justification to lower all interstate speed limits to 55 mph (88km/h). And Canada (ontario)followed suit lowering the speed limits from 75 MPH (122 km or so) on the 401 to the current 60 mph (100 Km/h). I use MPH because back then Canada used imperial measure like the US.
The US has sinced raised their speed limits back up and we have not. |

regardless thou i see your point, but personally i think enough people get killed or injured every year to justify us going even faster. Alot of our highways are just in too bad of shape or not designed properly for a truck to be doing much over 110 km/h |

I am guessing they did so because cars are more efficient today, BUT the average car now gets worse gas milage because the average car engine is so large today (SUVs). They should have left a lower limit, but then they would make the oil/car companies unhappy.
Keep them low, people in NA don't know how to handle fast cars or high speeds anyways. |

I started with heavy commercial 6 years ago so I can't comment on 10 years back. Schneider is in fact the largest trucking fleet in the world, I'd expect they'd have amongst the best tracking system.
I know that the speed, locations, when the ignition is in what position, time idling, etc is all available but it normally must be requested and downloaded from the service provider (as most trucking companies outsource their tracking.... that could be a major difference there, Schneider would do the bulk of theirs in house).
Regardless, I can assure you, most fleets that operate internationally now use goveners. As Schneider is self insured I've never had opportunity to deal with them but most of the big fleets are governed. |
