The driver of the bus
33Secondly, in respect of the driver of the bus, I am not prepared to find that he was negligent on the evidence that has been adduced by the plaintiff. I find that no relevant breach of duty of care has been established on the part of that driver.
34I have already referred to Miss Blacklow's description of liability as contained within the workers' compensation claim form that she had signed on 21 August 2003. As she had completed the formalities for claiming workers' compensation at an early stage, she had no further need to maintain recall of, or refer back to, the circumstances of the incident in a formal way until later interviewed by an insurance investigator for the purpose of these proceedings. This was apparent from her evidence.
35Miss Blacklow was next interviewed on 24 August 2004, at which time her statement of that date was not specific of the circumstances of the incident. Paragraphs 12 and 13 of her statement of that date simply state:
"12. On 21 July 2003 I was on my way home from work and travelling on a Westbus bus. We were travelling along Mount Street, Mt Druitt when the bus stopped suddenly due to another car.
13. I was thrown from my seat and put my left arm out to stop the fall. I then hit my head on the floor of the bus."
36Subsequently, on 26 February 2007, she was again interviewed by an insurance investigator. Her statement of that date, at paragraphs 6 to 12, relevantly states:
"6. On 21 July 2003 I finished work early at about 1.00 p.m. as I was taking time in lieu of extra hours that I worked and it was the last day of the school holidays. I had to wait for the next bus which was at approximately 1.30 p.m. which I caught from Oxley Park to Mt. Druitt so I can catch a bus home.
7. At approximately 2.50 p.m. I caught a Westbus bus, number 766" which was a Nipper bus, from Mt. Druitt bus depot near Mt Druitt station to travel home. That bus travelled around the corner and into Mount Street. I was sitting on the right hand side behind the first seat, facing the front of the bus. It was a two-seater seat and I was alone in it and was sitting closest to the bus aisle. There were other passengers in the bus but it was not full or crowded. The weather was fine and sunny. The road was dry.
8. The bus was travelling ( sic) along Mount Street in the left lane, closest to the kerb. I cannot estimate the speed at which the bus was traveling (sic) but he was not doing more than 60 klms (sic) per hour, which is the speed limit. As it approached the intersection of Mount Street and Luxford Road, the traffic lights at that intersection were green, a car in the same lane in front of the bus, suddenly stopped dead at the lights in the middle of the intersection. The bus driver applied the brakes and swerved to the right, to try and stop and/or not to collide with the car in front of him.
9. As a result I fell forward violently onto the ground, into the aisle of the bus. I put my arms out to try and stop myself from falling but I could not. My arms hit the floor and my forehead also hit the floor. The woman that was sitting in the front left seat fell forward into the bag compartment, which is near the bus driver.
10. I l ayed ( sic) on the floor momentarily and got myself up. I felt a pain straight away in my left shoulder. The bus driver was very upset about what happened. He asked me and the other woman if we were OK. I said that I was a bit sore but nothing that a hot bath won't fix. I was very embarrassed. None of the passengers came to my help.
11. The bus stopped at an angle across the two lanes, on the right rear of the car that had stopped at the lights. The bus driver called out to the driver of the car. As I got back to my seat I saw that car, which was a smallish new model sedan, red or maroon. The driver was a middle-aged woman and she had a male passenger in the front seat. The woman driver gave the bus driver a filthy look and turned right into Luxford Road from the left lane and drove off.
12. The bus driver then got the bus going and drove back into the left lane and continued on the journey."
37In my view, none of the matters outlined in these statements supports a finding that the driver of the bus was negligent.
38The driver of the bus was duty bound to take reasonable care whilst driving the bus, including by trying to avoid a collision that might occur as a result of the foreseeable actions of other road users.
39I accept that the bus driver ought to have readily foreseen the possibility of the vehicle in front stopping suddenly, and therefore he should have been in a position to take prompt evasive action in order to avoid a collision by appropriately braking and or swerving. In my view there is no evidence upon which it could be reasonably found that the driver of the bus had either driven or had reacted unreasonably, imprudently or negligently .
40There was no evidence of excessive speed on the part of the bus in the events leading to the collision. There was no evidence as to what, if anything, that might have caused the driver of the motor vehicle in front of the bus to stop suddenly, or whether that factor or those factors also operated to influence the actions of the bus driver in braking heavily and swerving.
41As is apparent from common knowledge, and from the appearance of the bus in the photographic exhibits and from the technical specifications of the bus, the driver would have most probably sat much higher up from the road than the driver of the vehicle in front, and would quite probably have had a good view of the road conditions ahead, including any potential hazards that may have required taking avoiding action of the kind taken by the bus driver in this instance.
42A flaw in the plaintiff's argument concerning the alleged negligence of the bus driver is that the only relevant road conditions that applied at the time involved the motor vehicle and the bus, and the application of the brakes on both of those vehicles, and in the case of the bus driver, swerving the bus to the right.
43Whilst there was no evidence called of the presence of o ther potential factors at play, I consider it would have been unlikely, that on a working day, at that time, at a traffic light controlled intersection, that the respective drivers had nothing but clear roadway ahead of them, including nothing between the motor vehicle and the bus.
44I accept that there is no evidence of other factors, but I nevertheless doubt that the road conditions were as sterile and clinical as the argument advanced on behalf of the plaintiff. It appears to me that the only reason the description of the prevailing circumstances is devoid of any additional descriptions that could have been forthcoming from the driver of the motor vehicle and the driver of the bus is that those drivers are simply not available to give evidence .
45Accordingly, I must proceed upon my analysis on the basis of the evidence that is available, such as it is.
46The plaintiff invoked r 126 of the Australian Road Rules , to argue that the bus driver failed to drive at a sufficient distance behind a vehicle travelling in front so as to enable safe stopping and to avoid a collision.
47In the present case, as I have already stated, it is not known what caused the driver of the motor vehicle in front of the bus to stop suddenly. Whatever had caused the sudden stopping of that vehicle, the driver of the bus certainly avoided a collision with the vehicle in front. In my view the bus driver adequately discharged any duty owed as a result of the requirements of r 126.
48The further argument made by the plaintiff is that the need for the driver of the bus to swerve is evidence that supports the conclusion the bus was not being driven safely, as required by r 126.
49The argument proceeded upon the premise that the bus should not have been driven so close to the motor vehicle so as to require the driver to employ such extreme braking and swerving so as to cause Miss Blacklow to be thrown from her seat. The flow in that argument is that there was no evidence as to how close the bus was being driven in relation to the rear of the vehicle in front.
50The argument continued to the effect that if there had been a more measured response by the driver of the bus in the circumstances, including to stop safely without swerving, the accident would not have occurred.
51The end point of that argument was that the bus driver had permitted the bus to come dangerously close to the motor vehicle in front so that nothing but an unsafe manoeuvre was available in the circumstances.
52The difficulty I have with that argument is that there is no description of the distances involved and of the surrounding events. Those events would necessarily include the prior speed of the motor vehicle, the distance it had travelled between the sudden application of the brakes and when it stopped, the speed of the bus before the brakes were heavily applied, whether there was a degree of lighter braking beforehand, which Miss Blacklow may not have perceived, the distance taken to stop the bus from the time the brakes were heavily applied, and any permissible analysis that legitimately emerges from the dynamic interaction of such factors, if known.
53In addition, there is the absence of any detail of other things that either may or may not have been happening on the roadway in the near vicinity, that could have influenced the actions of the driver of the bus. All that is available comprises the understandably limited observations of Miss Blacklow, who, from where she was seated on the bus, had not seen anything of the road conditions ahead before the braking and swerving manoeuvres of the bus . In my view, her statements, and the conclusions within those statements, must be read in that light.
54Whilst cases such as this must be decided on the available evidence, nevertheless, the decision must be rational. The absence of evidence of the surrounding factors makes it difficult to simply conclude, as the plaintiff seeks, by way of inference, that the driver of the bus was negligent, and that such negligence was the cause of the injuries suffered by Miss Blacklow, and therefore the cause of the loss suffered by the plaintiff for which indemnity is sought.
55In my view on the evidence adduced, the argued conclusions sought by the plaintiff are unpersuasive. Furthermore, it is the type of inferential reasoning concerning negligence and causation that has attracted the highest authoritative criticism: Derrick v Cheung [2001] HCA 48; at [13].
56Accordingly, I do not accept the arguments advanced on behalf of the plaintiff to the effect that there was negligence on the part of the driver of the bus, and that this was the cause of the plaintiff's claimed losses.
57In my view it has not been shown that the action of the bus driver in applying the brakes heavily, or in swerving the bus to the right to avoid a collision, involved any departure from the required standard of care.
