It's completely insane that the way it was registered, rather than the vehicle itself, determined its legality. Though it is typical of the government to miss the forest, because the trees were in the way.
Funny that windows determine passenger viability, rather than seats?
From '07 to '14, I drove an HHR Panel. It had neither windows, nor seats, behind the driver's seat. It was always registered as a passenger car though, because it was based on the Cobalt platform (very much a car)
I've never seen anywhere that pickup trucks were specifically excluded, just weight restrictions for old bridges.
Most of my life has been driving a pickup truck
On Long Island, the parkway system, was designed by Robert Moses in the early 1920s, when Long Island was a vacation Mecca for the rich in NY City. He deliberately designed the highways to be hostile to buses. His intention was the highways were for cars only (reported as an effort to keep lower income individuals riding in buses out of that Mecca. Robert Moses has been historically held in high esteem on Long Island.)
To accomplish that end, he made entrance and exit ramps with tight radii, and his coup de grace was the low overpasses that allowed cross roads to pass over the highways.
Ignoring that caveat could have disastrous consequences.
[Note: They are referring to the overpass as a “Bridge”. I always heard “overpass” possibly to distinguish them from full-access bridges.]
Off the top of my head, the affected roads:
Northern State Parkway (East/West)
Southern State Parkway (East/West)
Meadowbrook Parkway (North/South)
Wantaugh State Parkway (North/South)
Sagticos Parkway (North/South)
None of these roads were ever updated to allow bus travel. As a result, bus service to Jones Beach (and other beaches) requires that the bus travel on traffic signal controlled roads until Merrick Road ramp on either Meadowbrook or Wantagh State Parkways.
I lived on Long Island for 51 years and the entire roadway system favors cars. There are a few exceptions: Long Island Expressway (East/West); Seaford-Oyster Bay Expressway (North/South). There are also heavily travelled, traffic signal controlled multi-lane roads both East/West and North/South.
There might be others, but I cannot think of them now. I have not been back to Long Island for 27 years.
