No one wants new pipelines.  No one wants tanker trucks on the roads.  No one wants environmental damage.  No one wants ....  But 'government' wants more regulations.  Government has to reduce road maintenance because of past fiscal irresponsibility.  However Politicians do 'not' have to be fiscally responsible and sensible.
No one plans to have a traffic accident, especially someone driving a 100,000# vehicle.  However just like the drivers of cars, truck drivers have accidents.  Because of inattention, over driving, weather conditions, poor road maintenance and the interaction with other vehicles on the roads.  Namely cars and 4x4 pickup jockeys.  Those who pull out in front because they don't want to wait, those who pass unsafely and cut back in too close, those who refuse to either drive the speed limit or get over.  

However this article glosses over the actual cause of the increase.   A Government full of career politicians with no fiscal intelligence, only political graft.
