  • T-test for statistical independence used for p values. Preperiod from 1 January to 22 March; postperiod from 23 March to 23 April 30. Vehicle miles travelled presented per 100 million VMT. Single refers to single vehicle crash; multiple refers to MVC.

  • Bold Values note statistical significance <=0.05.
