What is the relevant evidence test in a personal injury action?

Only relevant evidence is admissible. (Evid. Code, 350.) The Evidence Code defines "relevant evidence" broadly as "evidence . . . having any tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action." (Id., 210, italics added.) " '[T]he trial court has broad discretion to determine the relevance of evidence.' " (People v. Tully (2012) 54 Cal.4th 952, 1010.) "On appeal, 'an appellate court applies the abuse of discretion standard of review to any ruling by a trial court on the admissibility of evidence.' " (People v. Hovarter (2008) 44 Cal.4th 983, 1007-1008.) A trial court abuses its discretion when its ruling falls outside the bounds of reason. (People v. Benavides (2005) 35 Cal.4th 69, 88 (Benavides).)
