Getting in car with drinking dad is not okay.
Drinking + driving with kids is not acceptable. Teach your kids to refuse to get in car with dad when he's had even one drink (cuz that doesn't mean it was the 1st of the day) and to call you for ride home. You must teach this lesson! They are teens and if they don't learn it from you (dad is incapable) they'll get in cars with drinking friends or selves and drive. See the big picture here. kids learn by example You must teach then what is acceptable.
