The appellant's submissions on the appeal
37On the issue of liability the appellant advanced six grounds of appeal which he addressed in some detail in his written submissions. He made the same submissions with respect to Ground 3 as were made with respect to Ground 1 and made the same submissions as to Ground 4 as were made with respect to Ground 2.
38Grounds 1 and 3 read as follows:
Ground 1:
The primary judge made a determination that was glaringly improbable being a finding at [18] that the respondent was not aware at the time of the collision that it had occurred.
Ground 3:
His Honour erred [53] by failing to take into account as a relevant consideration the fact that persons by the side of the road heard or perceived the collision contrary to the respondent's version and were the source of information being the registration number of the respondent that had been given to the appellant as opposed to his Honour's treatment of that evidence which only went to the issue of whether or not those persons could be found and any adverse inference to draw from their non-appearance at the trial.
39The appellant relied on the evidence with respect to the man who gave his name as Nathan Dodds and to which I have referred to at [17] above. It was submitted that the only rational inference to be drawn from that evidence was that the collision was audible and the sound significantly loud enough for others who were not on the road (such as Mr Dodds) but in its close vicinity to have heard the collision. Accordingly, his Honour's finding accepting the respondent's evidence that he did not know a collision had taken place could not stand as it was "glaringly improbable".
40In my view, this submission is unsustainable. It constituted a challenge to a finding which was clearly open to the primary judge to adopt based on his acceptance of the respondent's evidence that he did not hear the collision. This submission is surprising as his Honour found at [60] that the impact was of a glancing nature and caused no discernable damage to the truck, a finding which is not challenged. The fact that Mr Dodds had, presumably, heard and/or observed the collision is not capable of giving rise to an inference that the respondent must have heard the collision from inside the cab of his truck in circumstances where there was no evidence one way or the other as to whether or not he had his windows open. There was no evidence as to where Mr Dodds was standing at the time or whether he was close to or far away from where the collision occurred. As his Honour noted, no adverse inference could be drawn from the fact that Mr Dodds was not called. On the other hand no inference favourable to either party can be drawn from the mere fact that he offered his assistance to the appellant. As there is no evidence as to what Mr Dodds might have said had he been called, this finding of the primary judge of which complaint is made was not " glaringly improbable" as alleged. It follows that Grounds 1 and 3 must be rejected.
41Grounds 2, 4 and 5 are in the following terms:
Ground 2:
The learned trial judge made a determination that was glaringly improbable in that his Honour was not persuaded that anything about the appellant's vehicle ought to have put the respondent on notice, further the appellant had his blinker on but that ought not to have given any such warning to the respondent.
Ground 4:
His Honour erred by failing to determine that the respondent failed in all the circumstances to keep a proper lookout.
Ground 5:
His Honour erred by failing to determine that the respondent did not give way to the appellant's vehicle either pursuant to the Australian Road Rules or in the alternative in the exercise of reasonable care.
42It was submitted that the evidence established first, that the appellant had activated his right hand indicator which would have signalled to anyone who saw it that he was intending, when he could, to change lanes. Secondly, a photograph of the truck revealed a cabin that was higher above the surface of the road than that of the appellant's vehicle. Thirdly, the driver's cabin of the truck had a large glass front windscreen which, so it was asserted, would have provided him with a wide and elevated view for the purpose of enabling him to keep a proper look out. However, no questions were directed in cross examination of the respondent along the lines of this submission to suggest that he must therefore have seen the appellant's vehicle move towards lane 2 and heard the collision.
43It was further submitted that had the respondent been keeping a proper look out, he must have noticed that the appellant's vehicle was trapped in lane 1 and at some point needed to merge to the right into lane 2. Accordingly, the only possible inference that could be drawn was that the respondent was not keeping a proper look out for vehicles who were seeking to so merge.
44In support of those submissions the appellant in oral argument relied on the following passages from the joint judgment of Gummow, Kirby and Hayne JJ in Manley v Alexander [2005] HCA 79; (2005) 80 ALJR 413 at 415:
[11] ... But recognising one possible source of danger does not mean that a driver can or must give exclusive attention to that danger. Driving requires reasonable attention to all that is happening on and near the roadway that may present a source of danger. And much more often than not, that will require simultaneous attention to, and consideration of, a number of different features of what is already, or may later come to be, ahead of the vehicle's path.
[12] ... But the reasonable care that a driver must exercise when driving a vehicle on the road requires that the driver control the speed and direction of the vehicle in such a way that the driver may know what is happening in the vicinity of the vehicle in time to take reasonable steps to react to those events.
45However, neither of the above passages required his Honour to find that the mere fact that the appellant had engaged his right hand indicator light thereby signalling that he intended to move at some point out of his lane into the adjoining lane of itself required the respondent to take some particular action to enable the appellant to do so. Nor did they require the respondent to keep the appellant's vehicle under constant surveillance in order to be able to react in the event that the appellant decided at some indeterminate point on the roadway to attempt to move in front of the respondent's truck.
46The foregoing has particular force given that the appellant's evidence, apparently accepted by the primary judge, was that when he commenced to move out of lane 1 the respondent's vehicle was only three metres behind the rear of his vehicle and travelling at a speed of at least 40 kph. I can accept that had there been a substantially greater distance than three metres between the two vehicles, such as to have enabled the respondent to observe the appellant's vehicle moving to the right into the respondent's lane in a more gradual movement than what appears to have been the case, then no doubt the respondent had a duty to take reasonable care to ensure that he did not collide with it. He may have had to apply his brakes to slow up if he considered that he was getting too close to the appellant's vehicle. But that was not this case.
47The problem with which the appellant was faced, as the evidence established, was that it was not until he was 15 to 20 metres from the end of lane 1 that he judged that there was a sufficient gap in the traffic in lane 2 into which he could move. The inference to be drawn from that is that he moved very suddenly to the right for otherwise he was going to run out of road space. The evidence was clearly sufficient to justify the primary judge's finding (at [61]) that the appellant simply misjudged the situation and, in particular, misjudged the gap between his and the respondent's vehicle as being sufficient to enable him to move safely in front of that vehicle without colliding with it.
48The appellant in oral argument acknowledged that his submissions were necessarily predicated upon the assumption that when he decided to move out of lane 1, his vehicle was in front of the respondent's truck in lane 2. As I have noted at [47] above, the primary judge seems to have accepted that this was so at [59] of his reasons, albeit that the extent of separation was only three metres. However his Honour also found (at [60]) that the respondent did not observe the appellant's vehicle commence to move into lane 2 and was not aware of any impact between the two vehicles.
49The fact that there was no damage to the front of the respondent's truck and that his Honour's findings (at [60]) that the impact was of a glancing nature and occurred at the bottom of the near side of the rear section of the truck (at [17]), leads inevitably to the conclusion first, that it was the appellant's vehicle which collided with the rear section of the respondent's truck and, secondly, for that to have occurred the appellant's vehicle could not have been in front of the truck as he asserted.
50Recognition of this fact was sought to be met by the appellant asserting, and his Honour rejecting (at [41] - [42]), the allegation that on observing the appellant commencing to move out of lane 1, the respondent deliberately accelerated his vehicle in order to close the gap between them so as to prevent the appellant from moving in front of him.
51Ultimately, in oral argument, the appellant accepted, properly in my view given the evidence, that once it was acknowledged that the point of collision was on the silver metallic strip along the bottom of the rear section of the truck, that was the end of his case subject only to the acceleration issue which his Honour, in my opinion, was entitled to and did reject.
52But even if the appellant's vehicle was some three metres in front of the truck when the former commenced to move out of lane 1, the appellant's case depended, as his counsel acknowledged, on the following propositions. First, the respondent knew that lane 1 was a merging lane and was therefore going to terminate; secondly, he ought to have observed the fact that the appellant had activated his right hand indicator on; thirdly, the respondent should therefore have anticipated that the appellant would need to move into lane 2 before he came to the end of lane 1; and fourthly, he was under a duty or obligation to slow down to permit him to do so safely and his failure to do so was a breach of his duty of care.
53Not only was the respondent not under the duty referred to but Rule 148(1) of the ARR mandated the appellant to give way, not the respondent. There is nothing in the principles in Manley relied on by the appellant which required the respondent to respond to the appellant's need to move lanes by slowing down and giving way to him.
54Accordingly, in my view, no error on the part of the primary judge has been demonstrated to suggest that it was not open to his Honour to find that the respondent was not guilty of failing to keep a proper lookout or that he was in breach of his duty of care by failing to facilitate the appellant's need to move from lane 1 into lane 2. Grounds 2, 4 and 5 should be rejected.
55Ground 6 reads as follows:
His Honour miscarried his function as the trial judge by drawing inferences against the appellant's case which did not have a sound basis on the evidence and accepted the respondent's evidence as to the version of the collision in circumstances where the respondent gave evidence admitting that he had a poor recollection of the events leading up to and causing the collision and that the conclusions of the Trial judge in favour of the respondent were glaringly improbable.
56This ground does not in substance differ from Grounds 1 and 3. It contains an assertion that the primary judge should not have accepted the evidence of the respondent that he did not see the appellant's vehicle and/or was unaware of the collision. It is a nonsense to submit, as does the appellant, that the primary judge's function as a trial judge miscarried when he accepted the credibility of both witnesses but yet accepted the respondent's evidence that he had no recollection of the collision.
57There is, of course, no inconsistency between his Honour accepting both the appellant and the respondent as honest witnesses as well as accepting the version of each of them, namely, that the appellant attempted to move into the lane in which the respondent was travelling when the two vehicles were a mere three metres apart and the evidence of the respondent that he simply did not see the appellant's vehicle or hear or understand that a collision had taken place.
58Nevertheless, in his written submissions, the appellant asserted that it would be "incredible" if the respondent did not know that a collision had taken place despite the fact that it had been heard by others by the side of the road or in close proximity, a reference apparently to Mr Dodds. I have already dealt with this submission which has no substance.
59It was next submitted that given the amount of damage to the appellant's vehicle, it could only be speculative that there was no apparent impact, noise or vibration in the respondent's vehicle so as to give him notice that a collision had in fact occurred. The difficulty with this submission, as I have already observed, is that there was no damage to the respondent's truck and his Honour found that the impact was of a "glancing" nature which would explain why the respondent was unaware of it.
60The appellant's written submissions then asserted that notwithstanding the primary judge's findings that the respondent did not observe the appellant's vehicle commencing to move from lane 1 to lane 2 and that there was nothing about that vehicle or the manner in which it was being driven which alerted or ought to have alerted him to the fact that it was about to change lanes, nevertheless there was a breach of the respondent's duty of care in such circumstances as he should have had in contemplation that it was likely that a vehicle in the merging lane would make an attempt to move into the adjoining lane thus requiring the respondent to travel at a safe speed and to keep a proper look out in the event that that manoeuvre materialised.
61In my view this submission has no merit for the reasons stated at [52] - [53] above. It in effect required the respondent to be a mind reader. He was entitled to assume that any vehicle wishing to move from lane 1 to the adjoining lane would do so safely when there was a sufficient gap in the line of traffic to enable him or her to do so. On the appellant's own case, there was an insufficient gap notwithstanding the appellant may have thought it was sufficient. It was only three metres and the respondent's vehicle was travelling possibly in excess of 40 kph but less than 60 kph.
62A gap of three metres when the respondent was travelling at least at 40 kph and the appellant between 30 and 40 kph simply did not provide a sufficient space into which the appellant could move in a manner which would alert the respondent in sufficient time to enable him to react in an appropriate manner such as slowing his vehicle.
63Essentially Ground 6 is one asserting that it was "glaringly improbable" on the evidence for the primary judge to accept the respondent's evidence that he did not see the appellant's vehicle before it intended to move out of lane 1 and that he was unaware that the appellant's vehicle had collided with his truck. There is no merit in this submission for the reasons already given. The appellant's vehicle would have been one of a number in lane 1 which probably had their right hand indicator activated. There was nothing special about the appellant's vehicle which did not apply to those vehicles which were travelling in lane 1 in front and behind him. There is no substance in Ground 6 and it should be rejected.
