Grandfathers in trucking

Regulators often are legally constricted to making regulations only astir early vehicles aliases infrastructure. Existing vehicles and infrastructure often get “grandfathered,” meaning they are permitted to run nether nan caller rules moreover though they do not needfully comply pinch them. There are a fewer instances wherever rules tin beryllium retroactively applied, but regulators often are conscionable happy pinch taking nan early wins alternatively than arguing complete a decreasing organization of older vehicles and infrastructure.

To put that successful societal terms, Baby Boomers are permitted to reminisce astir nan 1950s and '60s successful beforehand of their Gen X, Gen Y and Gen Z offspring, because Baby Boomers were calved earlier societal mores made reminiscing passe.

Vehicle size and weight regulations person a batch of grandfathered clauses. A sane individual mightiness reasonably reason that immoderate motortruck and trailer driving connected nan roadworthy tin legally spell anyplace successful nan country, but, alas, that is not nan case. When national interstate web size and weight regulations were adopted, regulators had to admit that each authorities had antecedently evolved its ain unsocial rules, and alternatively than conflict that conflict nan feds constricted caller rules to what they had authorization over: nan national interstate road system.

Trucking groups and conveyance shaper manufacture groups often kick to nan national authorities astir really regulations are not azygous crossed nan country, and yet, it’s not really nan fed’s fault. Those divers rules were created astatine nan authorities level, and nan joys of our strategy of authorities is that what happens successful nan state, mostly stays successful nan state, to get a Vegas phrase.

The Federal Highway Administration (FHWA) keeps tabs connected these authorities exemptions. You tin find them connected their Compilation of Existing State Truck Size and Weight Limit Laws website. You would deliberation nan various authorities trucking groups would beryllium each for reducing complexity and truthful would standardize rules. In politics, however, logic and logic do not ever prevail. Vested interests abound to power authorities norm making. There besides are beingness conditions that whitethorn differ. For example, infrastructure successful Massachusetts whitethorn person been built to different standards than successful Idaho, conscionable because of nan differing ages of nan roads and bridges.

I’ve driven connected authorities roads successful Arkansas, beautiful scenic routes wherever I would ne'er effort to thrust a semi pinch a loaded trailer. While successful Nevada, I’ve seen triples moving connected godforsaken roads. Nevada has an exemption to “allow vehicles to run up to 129,000 lbs. GVW connected parts of nan Interstate System.” In Washington state, I’ve seen semis connected authorities roads pulling containers pinch gross conveyance weights of 105,000 lbs., and connected immoderate routes moreover more.

States besides tin supply individual exemptions done overweight permitting. There are moreover “heavy haul business corridors” successful Washington authorities wherever “special overweight permits for this way whitethorn beryllium issued up to a GVW of 139,994 lbs.”

My cynical position connected overweight permitting is that if you salary capable for it, nan authorities will fto you do it. I ever wonderment really nan civilian engineers consciousness astir that aft they cautiously designed nan bridges and roads for different weight limits. I’m judge location is immoderate statistical rationalization that nan “occasional” overweight conveyance does not correspond a important risk.

I besides person issues successful that regulations look to person been focused connected managing individual vehicles. Concepts for illustration platooning, whether quality aliases autonomously controlled, coming perchance caller challenges to regulators if 2 aliases much vehicles tin inhabit little abstraction than expected crossing a bridge. I expect it is reasonably challenging legally to modulate aggregate vehicles operating successful performance successful nan existent world. There could beryllium aggregate tractor OEMs, aggregate trailer OEMs, aggregate fleets and aggregate drivers involved. Who would return work for nan full group?

Interestingly enough, size and weight regulations look immutably linked to emissions systems. FHWA identifies 40 states pinch emanation simplification instrumentality exemptions. Many of these exemptions let for added GVWR arsenic an offset for requiring little emanation technologies specified arsenic idle simplification systems aliases replacement fuels. For example, nan authorities of Alabama allows an further 400 lbs. for idle simplification devices “which applies to axle weight, gross conveyance weight, aliases span look weight, up to 400 lbs. aliases nan certifiable weight of nan unit, whichever is less.”

Farmers, ranchers, discarded haulers and loggers look to person a batch of exemptions. Every commodity has defense groups exerting power connected governmental determination making. Some groups are much successful than others astatine carving retired regulatory exemptions.

When I was a teen and contemplated a profession successful engineering, it really didn’t dawn connected maine that successful clip I would request to understand nan ineligible system, nan governmental system, trading and sales, on pinch nan evident knowing of engineering. Everyday fleets and OEMs look a complex, illogical world of local, authorities and national regulations.

We each person participated successful making nan freight world what it is, done voting, aliases not voting, influencing aliases not influencing, done tribunal actions and paying taxes, and vicariously done each our grandfathers.

Wouldn’t it beryllium absorbing if we could commencement pinch a blank expanse of paper; 1 wherever local, authorities and national rules were each nan aforesaid and nary exemptions were required?

But then, wherever would we beryllium without our grandfathers?
