I certainly can't speak for other states but I found some confusing info regarding NY in comparison to what is listed on this PDF...quoted as follows:
New York
For unloaded vehicle, no more than 30” of clearance between ground and front or rear bumper.
headlights:Maximum height 54” above the ground
tailights:Maximum height 72”.
Total vehicle height, loaded or unloaded, not to exceed 13’ 6”
first comment...I'd like to see a lifted truck hit 13'6" that is NOT a monster truck....
that being quoted..I'll move to the NY DMV's site...taken directly from them:
Equipment required for passenger vehicles (
http://www.nydmv.state.ny.us/forms/mv529.pdf
BUMPERS
On the front and rear, each must be securely fastened with some part of the bumper located between 16” and 20”
above the ground. The bumpers provide protection against damage affecting front or rear external lamps, body parts,
and vehicle occupants during low-speed impacts. This provision does not apply to a vehicle registered as an
historical vehicle.
and I'm not done:
Equipemnt required for commercial vehicles:
mv 529a
http://www.nydmv.state.ny.us/forms/mv529a.pdf
BUMPERS Required on 1990 or newer models, except tractors, or special purpose commercial vehicles registered in this state,
which are constructed so the body, or the chassis assembly without the body, has a clearance at the rear end of more
than thirty inches from the ground when the vehicle is empty, unless the rear end of the vehicle or combination of
vehicles is equipped with bumpers or devices serving similar purposes, that are constructed and located such that:
(1) some part of the bumpers or devices are at least sixteen, but not more than thirty inches, above the ground when
the vehicle is empty; (2) the maximum distance between the closest points between bumpers or devices, if more
than one is used, does not exceed twenty-four inches; (3) the maximum transverse distance from the widest part of
the vehicle at the rear to the bumper or device does not exceed eighteen inches; (4) the bumpers or devices are
located not more than twenty-four inches forward of the extreme rear of the vehicle; and (5) the bumpers or devices
are substantially constructed and firmly attached. Vehicles constructed and maintained so the body, chassis, or other
parts of the vehicle afford the rear end the protection contemplated, shall be considered to be in compliance.
Alright so let's cut through this...by the post's original link, the second section (529a) would seem to match up, and in fact if you read that carefully it would also seem to imply that something like my 89 Ranger would not even require bumpers....
Now before you jump me about it being commercial vehicles...
in NYS, a pickup is generally licensed with commercial plates, unless you apply for passenger plates which requires it be under a certain weight and not have any commercial/business ads on it, and it not used for a business etc etc..
This being said, when I had registered my truck in NYS, I got passenger plates, and therefore, in theory, I would have to abide by section 529 and not 529a, which would require I have bumpers and they not exceed 20" from the ground...
this in of itselft is almost amusing, because while I have 29's on the truck as opposed to stock 28's, the lowest part of the front bumper (not the valance) is 18" now.
To me, the implication here is: if you want to lift your truck in NYS and keep it street legal, make sure you pay the extra couple bucks for commercial plates.
This being said, the other note I have on bumpers is this...it doesn't surprise me someone could get their mechanic to pass the inspection but...I've seen at least one new Ranger (say late 90ish) running around here with a roll pan. By what I think I read in those regulations, they probably shouldn't be..so how is they don't get pulled over and ticketed?
I'm looking into PA's regulations next if I can ever get PennDOT's sites to work right..
