Can a California employer still insure you as a mechanic after a DUI?

that depends on if you will be driving the vehicles that you will be working on if you are going to be driving them then the answer is no, if you are not going to be operating the vehicles then it should be absolutely no problem. Next time you drink just don't drive and you will not have this problem. if you still have a d.l. you should be able to drive the cars if they want to put you on their insurance.
