Who's going to be the designated driver tonight?

今晚谁来当指定驾驶。

I was the designated driver, they drank too much and on the way home hooked up in the back seat.

我被指定为司机，他们喝的是在是太多了，然后他们俩就在后座上勾搭上了。

After you finish watching the Indy 500 this Sunday, you may want to have your designated driver take you home.

当你看完这周5的indy500大奖赛后，你也许会希望你指派的司机送你回家。

No, I won't be drinking tonight because I am the designated driver. Just give my glass of wine to the designated drunk.

不行，今晚我不能喝酒，我还要开车呢。把我的酒给他代喝好了，要是醉了也算他代醉。

If you're the designated driver, or just abstaining, here's a non-alcoholic drink you could sip all night long: seltzer water mixed with a bit of 100 percent fruit juice.

如果你是个司机或是正在戒酒, 这也有你可以整晚品味的无酒精版饮料: 用苏打水加兑一点100%的纯果汁就好了.
