Your
Car Passed… But That Doesn’t Necessarily Mean It’s Safe To Drive

Ive got
a friend who owns a car repair shop. Hes an officially authorized
state safety inspector. The guy who goes over your vehicle and gives
you a sticker (well, after you pay for it) if your car passes
muster.
The other day
I was hanging out over at the shop, chewing the fat with him while
he was inspecting someones car. A minivan, actually. All four
tires were nearly bald. Two of them had absolutely no outer sidewall
tread left; the shoulders were as smooth as glass.There was still
some tread left on the inner section of the tires, though it was
razor thin.
Fail
right?
Pass,
actually.
My friend explained.
State law says an individual tire has to have the treadwear bars
showing across the entire length of the tread and in several
sections of the tire before it fails. In other words, a tire can
be partially bald even have a complete flat spot and
still be legal even though its obviously not safe. A tire
such as the tires on this particular minivan would, for example,
be very likely to hydroplane because theres insufficient tread
depth to dissipate the water on the road. But technically
legally my friend could not fail the vehicle. All he could
do was note on the customers receipt that the tires were worn
to the limit of legality and advise him that he really ought
to consider getting new tires. Soon.
Case two:
My friend told
me about brake inspection procedure. The law written by bureaucrats
and politicians, not technicians or even people who do their own
oil changes says he cant fail a car for brake problems
even if the area around the wheel cylinders (a hydraulic piston
with rubber seals) is clearly moist sure evidence
of a leak. And if a hydraulic system such as your cars
brakes is leaking, it means your brakes probably arent
working right or soon wont be. But my friend cant
fail you unless he sees drips not merely evidence
of moisture. Because hes not allowed to check further. He
by law, as he explained it to me cannot probe/pull
back or otherwise look behind the rubber dust boots on the wheel
cylinders to check to see why the area around there is moist. Because
bureaucrats people who know nothing about cars or how they
work decided this would result in possible damage to the
rubber dust boots, which (apparently) had annoyed some influential
(but car-ignorant) muckey-mucks, who put pressure on the appropriate
legislative body to have the law changed so as to forbid an inspector
like my friend from probing further. Even though any sign
of moisture around a wheel cylinder is clear evidence of a leak.
A slow leak or a small leak, perhaps. But a leak, nonetheless
and bad news, if you give a damn about being able to stop.
The Law doesnt
give a damn about that. What it does give a damn about, is safety
theater making the vehicle owner who goes in for the
mandatory inspection feel safe if his car is duly stickered.
Even if, in fact, it may not be (safe).
My friend finds
it all very frustrating. Hes a conscientious guy and tries
to tell people, based on his expert opinion as a master mechanic,
that they probably ought to get their brakes fixed, or buy a set
of tires. But he still has to pass their vehicles, based on the
non-expert standards and procedures set forth in the states
book. Or, if his expert opinion is trumped by the non-expert
opinion of a cop. In my state (Virginia) the state safety inspection
system is overseen by the state police not the DMV (not that
that would be any improvement but still). Every once
in awhile, a state cop shows up at my friends shop to look
around. The cop will also arbitrate disputes, as when a vehicle
owner contests a failed inspection. The interesting
thing is the cop is, well
a cop. Hes a law-enforcer.
Not an ASE Master Technician or even a Do-it-Yourselfer. Yet his
opinion in a dispute over a technical question becomes the Final
Word.
Most people
who bring their vehicles in for the safety theater performance have
no idea about all this. They just assume that if their vehicle gets
a sticker why, it must be safe since, after all, the sticker says
so. The sticker absolves them of all further responsibility from
making sure that their vehicle is in fact safe sticker or
not. For the next year, people like the owner of the minivan with
the near-bald tires will motor on because that sticker is
good for a full year, even if the tires may not be good
for more than another month. Same story with the brakes.
So long as they passed yesterday, no need to think about
them tomorrow. Or next month. Or six months from now, when the little
leak becomes a big one and the system loses hydraulic pressure during
a panic stop and you pile-drive into the car ahead that slowed down
unexpectedly.
But hey, your
car passed.
The point to
take away from all this is simple: Dont assume your car
or one youre thinking about maybe buying is in perfect (or
even good) working order just because theres a sticker on
the windshield.
Its ultimately
up to you to be sure.
