2. PLAN YOUR ROUTE
If you have been lucky enough to have the luxury of time, plan your route. Failing to plan is planning to fail. Also run through the entire route on the day before the operation. Scout the road for potential hazards and take note of how the traffic flows. If there's a traffic jam, think about how you can minimize the time stuck in traffic. What's the cause of the job? Is there a safe alternative route? How are the cars lining up? Pay attention to junctions and look out for possible sources of attacks.
And on the actual day, take note of the things you saw and see if there's anything along the route unusual from the day before; a sudden roadwork zone or a police stop zone. Pay attention to the construction tent; is there something inside that shouldn't be there? And if there are police, see if they are real policemen.
