听力原文：W: Okay. May I see your driver's license, please? M: What? Did I do anything wrong? W: License, please. And your car registration. M: Oh, yeah. It's here somewhere in the glove compartment. Yeah, here it is. W: Sir, did you realize you were speeding in a school zone? M: What? No, I didn't, but that's probably because my odometer is broken, I mean, malfunctioning. W: Yes, you were going 50 miles per hour in a 20 miles per hour zone. And, you failed to come to a complete stop at the intersection back there. M: Rolling stops don't count? W: And, one of your break lights is out, you're not wearing a seat belt, AND your driver's license expired six months ago. M: Hey, my wife's cousin's husband works for the police department here. Or was that the fire department? Anyway, I thought you might be good pals, and you know ... W: Hey, are you trying to influence an officer? I could have this car impounded right now because of these infractions. M: No, of course not. W: Okay, then. Here's your ticket. You can either appear in court to pay the fine or mail it in. Have a nice day. Why is the man made to show his driver's license?
