AAA Insurance policy: Hydroplaning on an incline, who is at fault?

I actually did a study on this particular subject matter and escaped all blame. My insurance company thought it was a brilliant report. You have no control over gravity when going down the hill. Some responders on here seem to be a bit ignorant in the physics of hydroplaning.

Tidbit to remember about hydroplaning: the tire is no longer in contact with the road. A layer of water forms between the tire and the road and tires essentially become water-skis. The water layer forms because the tire can't push the water out of the way fast enough. If there is one to blame, it would be gravity.

Update 9, consider yourself lucky since you were at fault for driving too fast for conditions.

Whenever you hit someone from behind them you are at fault, unless they are backing up. Now in a chain collision you might be able to get the car behind you to cover it if you were driven into the car in front of you.

You've already made up your mind, no need to ask then, is there? Quite simply, if you can't convincingly pin it on someone else, it's your problem.

You are. When it's raining, you are supposed to drive slower so that you don't hydroplane.

You did not keep full and complete control of your vehicle and failed to stop before colliding with the other vehicle

You are 100% at fault and liable for any damage to the other vehicle. If you have collision coverage, the cost of repairs, less the deductible will be paid by your insurance unless they deem the car totaled, in which case you will be paid the valued of your car less the deductible ,

was/is there not a different street or road that you could have/can drive on ?? especially with the knowledge that you have, one would think that you would always drive on a different road, at least when it's raining !!

Hydroplaning on wet roads is strictly a matter of speed and tire inflation. Water frequently collects on roads and it is our responsibility to ensure we are below hydroplaning speed when we enter a wet area. See the source for the calculation.

If you rearend the car in front of you, you are at fault. Hydroplaning sometimes means tires with low or no tread.

you are. too fast for conditions. or defective vehicle [tires] causing accident

that the safe speed under those conditions was zero is immaterial. law requires to you drive only the safe speed.
