Well whatever the legal limit is. I had one mixed drink then got a call to be someplace and was pulled over. I blew a .013. Then they wouldn’t even take blood to prove I wasn’t drunk. I fought the case and had it knocked down to open container.

So state police in rural areas will arrest then release you to a family member. I’ve actually seen this happen to two different people. One was released then went straight to his car the other went to bed woke up 8 hours later and got his car and still blew over 0.6
