I was riding down the trail and came up on another snowmobile going slower. I followed him, both of us on the right side of the trail, for about 2-blocks when he pulled over to the far left side of the trail,then almost came to a complete stop. I thought he was letting me by. I proceeded on the right side of the trail at about 10 mph to go by him. Then he made a 90-degree right hand turn through the brush and then I T-boned him at about 5-mph. When I asked him why he did that he said I did not think anyone was behind me. It cracked his belly pan and bent my left ski and control arm to the cost of $353.48 to fix my sled. Was he at fault to make a hard right from the far left side of the trail? Or is there a % of me/him at fault. Or am I at fault here. we both exchange names , addresses and phone numbers and I would like to farther pursue this matter. Any Legal answers would be Greatly appreciated! .............Thank You. p.s we both have $500 deductible on our insurance.
