The ultimate decider of liability in a ride-sharing accident is a jury. However, it is unlikely your case will get to a jury as the majority of cases are settled without a trial. Liability can be clear-cut (rear-end collision) or disputed (green light crash). The parties will likely come up with a decision on where liability lies and argue their position with the other side. The real question is how much compensation you can get for a ride-sharing accident and liability will be tied into your damages and the available coverage.
