What is the test for voir dire in a personal injury case?

However, we wish to express a caveat: Although the trial judge has a duty to restrict the examination of the prospective jurors within reasonable bounds so as to expedite the trial ² (People v. Dorsey (1974) 43 Cal.App.3d 953, 966, 118 Cal.Rptr. 362), the fixing of an arbitrary time limit for voir dire in advance of trial is dangerous and could lead to a reversal on appeal.
