Anyone who has driven a car for very long has experienced an unpleasant red-light encounter. The light changes, the driver in front is slow to move. The driver behind honks his horn. Tensions rise in both cars. But Lauri Curti's trouble with Lee E. Stratton deteriorated way beyond the norm, Curti alleges in a lawsuit filed Wednesday. While Curti was stopped at a light in her 1986 Mercury Lynx, Stratton "became enraged" at Curti's driving, "approached her on foot, verbally assaulted her" and shattered her windshield with his fist, the suit alleges. Curti was injured seriously and permanently by flying glass, says the lawsuit, so she wants compensatory and punitive damages. None of the parties to the suit, nor their lawyers, could be reached for comment.
