W: Oh, yes. I was standing outside the bank building and I saw it all quite clearly.
M: Do you know what time it was?
W: Yes, I checked my watch. It was a quarter to three exactly.
M: Good, Now, how fast was the truck moving?
W: Well, quite slowly -- about l0 miles an hour. It was coming up Garden Road. I suppose the truck driver knew the lights were going to change. But they were still red when he went over them.

W: It was coming along South Street about 30 miles per hour. It was a blue Toyota. The driver stopped his car when he saw the truck crossing.
