(1) Mr. Brown (the motorist)

     At about 9:20 p.m. on October 14th, I was driving along Market Road in the direction of Midwick.

I wanted to go to Sturham to collect my wife, who had been visiting some friends. I prepared to turn into

Sturham Road, which was on my right. In the distance, I saw the lights of a car moving towards me but it was along way from me. I put out my hand to show that I was going to turn right. Then I started to turn

slowly towards Sturham Road. Suddenly there was a loud noise on the passenger's (near) side of the

car. I stopped the car and got out. A motorcycle had hit my car. The motorcyclist had been thrown over

the car. He was injured, so I ran to a shop to phone for help.

(2)  Mt. Smith (the injured motorcyclist)

     On the evening of October 14th, I was going home along Market Road towards Newtown. I was

riding my motorcycle. I was going slowly because some of the streetlights were out and road was wet

and slippery. Just before Sturham road, a car suddenly drove right across my path. The driver did not

flash his lights to give a warning. I could not turn in time, so I hit the side of the car. When I woke up, I

was lying in a hospital in Market Road.

(3) Mr. Lee (another motorcyclist) 

     At about 9:10 p.m. on October 14th, I left my home in Midwick. Ten minutes later I was riding my

motorcycle along Market Road. I was going to Newton. There was a motorcycle about 40 meters in

front of me. It was not going very quickly. The man on it was riding near the curb (路边) but I was near

the center of the road. The motorcyclist in front of me tried to turn to his right but there was no time. He

hit the car and was injured. There was no car going along in front of us o put by the road.
