I agree, that "sense of urgency" does exsist but it's up to the employee to resist that urgency when behind the wheel. It's not that hard, just look at how many drivers are on the President's Safety Team (15 years of safe driving).
Do you not agree that 3 in 12 is a pretty lenient policy?
In Master Freight its 3 in 9 months will get you terminated. I'd say its lenient.
