law... what law?
maybe to get insurance...
but never heard of that law and who would inforce it?
how many mom & pop gas stations fix cars and no one is certified?
remeber mecp is a indipendent company - no controled but the government . they set there own rules & tests.
Dont get me wrong I am for certification & training, I have seen many installers screw up and a little knowledge would have saved the company some money. but as i as said before This area doent pay installs shit.
