Thanks for another GREAT photo story,
Tim ...
It would appear from the skid marks that the "eye witnesses" may not have given the police very good information.
The rear end of the wrecked motorcycle shows scrape marks on the pavement suggesting that the point of impact was after the taxi slammed on his brakes
The scrape marks on the pavement from the rear end of the wrecked motorcycle and the skid marks from the taxi seem to tell a different story than the one given to he police by the "eye witnesses."
The motorcycle scrape marks move away from the taxi at it's present position. The skid marks from the taxi appear to have occurred prior to the point of impact with the motorcycle.
Had the motorcycle hit the taxi after overtaking the tractor, the taxi would have continued on past the point of impact and the taxi's skid marks would have begun after (rather than before) the point of impact.
The motorcycle scrape marks and the taxi skid marks suggest a different story than the one told by the "eye witnesses" ... BTW, who were these "eye witnesses' ... the half asleep tractor driver, the whiplashed passenger and the "lost" taxi driver?
A motorcycle is a very maneuverable vehicle with excellent visibility. Had the taxi actually been "hidden" by the tractor (which is highly doubtful), the motorcycle driver would have had sufficient time to correct his error (especially since there doesn't seem to have been any oncoming traffic).
However, if the motorcycle was passing the tractor and then, suddenly, the taxi driver slammed on his brakes (because he missed his turn or an animal darted out in front of him or he dropped his coffee in his lap), then there would not have been sufficient time for the motorcyclist to react.
Unfortunately, although the taxi driver probably caused the accident, the law states that you must have your vehicle under control at all times and it would seem that the motorcycle driver did not anticipate the abrupt stop made by the taxi driver.
Well, that's my "police" report,
Tim ...
Please tell us what really happened ...

All the best,
Richard
