W: The other driver said that he stopped at the junction. When he pulled out there was nobody coming, so you must have been speeding.
M: Well, it’s not true. I’ve witnesses to prove it. He couldn’t have stopped. The lighting is very good here along this stretch.
W: Yes. He should have stopped. Why did you stop at the pedestrian crossing?
M: There were two old ladies on it I’m always a bit careful with old people because they’re likely to walk across the road without looking properly.
W: I shouldn’t worry, sir. We don’t think you were speeding—even without measuring the skid marks.
M: Er, was he, the other driver, drunk?
W: I don’t know yet. He’s admitted that he’s had one or two drinks, but says it was only two half-pints. We’re going to give him a breathalyzer test to see whether he’s over the limit. If he is, he’ll be asked to have a blood test.
M: Well, I haven’t touched a drop all night!
W: No, sir. It’s surprising how much a driver’s breath smells even if he’s only had one drink. Well, sir, I don’t think I need to detain you any longer. We shall want written statements from you, your wife and the young lady tomorrow.
M: Yes. What’ll happen to my car? It’s obvious that with that badly-damaged wheel I shan’t be able to drive it.
W: We’ll have to take some measurements of the skid marks and the positions of the cars. We’ll arrange to have it towed away when we’ve finished. If you ring the police station tomorrow, they’ll tell you what to do.
M: Thank you very much.
W: Oh, by the way, is the young lady staying with you?
M: No, she’s a friend of my wife. She’s staying at the Station Hotel. Her name is Becky Softe. She has a friend with her and she’ll need to be told about the accident, I suppose. I don’t know...
W: We’ll see to that. I expect you’ll want to go to the hospital to see how your wife is.
M: Yes, I must go there now. I told my wife to wait there until I could collect her in a taxi. I hope they don’t keep her in.
W: If you feel well enough, you can get a taxi just around comer.
M: Yes, I’m fine. Good night.
W: Good night.
