Don't sweat the small stuff... save your rage/worry/disappointment for the big shit that (if you are unlucky) goes down.
I had 4 teens...at the same time (the eldest three are a year apart each and then the youngest 3 years after) The girls... moody, got drunk at the park, fought over clothes but otherwise weren't too bad.
DS1 however... was evil. he turned into a raging angry ball of hormones. He stole from us, punched holes in walls... did all sorts of unbelievably stupid and dangerous stuff.
The ONLY thing that got us through, was a) being consistent. We had to grey rock his attempts to provoke us, but whenever he was faintly pleasant we engaged. B) hung on to the thought that THIS WILL PASS. It did. He started becoming human again at 17 and he is now a lovely, respectable adult 
Don't threaten consequences if you aren't going to follow through... but it it's serious, BE serious.
TALK. Car journeys where they don't have to make eye contact , can be brilliant for really chatting .
Enjoy them. Some teens sail through, others (like DS1) struggle, but they are amazing emerging humans, figuring out their way in the world. Mine turned my hair grey, I swear, but they were also wonderful (in between slamming doors)
Give them chances to BE responsible, to BE independent.. don't smother.
I told mine that if they ever felt peer pressured into doing something, that deep down they knew was a really bad idea, they could back out by saying I'd grounded them/ was making them visit a relative or whatever... they could pretend I was a mean cow!
DD2 said her friends thought I was horribly strict, but it was her get out clause and she used it a few times :)
