What if they don't make enough to pay for it? Never mind, that's a rhetorical question, we all know the answer.
The only way I see even the fleets paying this outlandish level of toll is if they could get certain loads across Texas faster.
Are they looking at higher speed limits on this road? Most probably not.
So there's the answer right there: increased costs for not much increase in time savings means truckers won't use it unless the alternative roads are absolutely clogged.
Truckers will use an alternate route that costs them money if it does one of two things:
1. Allows them more miles per logbook hour.
2. Avoid scales or inspection points, which also costs them time (and hassle).
Unlike folks just motoring along in their cars, truckers have limits on how many hours per day they can be driving, how many hours they have to spend off the road, etc. Their job is to move the load the maximum number of miles in those 10 hours they can drive per day.
