Before You Commit

Are your flaggers certified as my state requires?
Can you draw and submit the traffic control plan and permit?
Does the setup follow the MUTCD and state supplement?
Are you insured, and can I be added as additional insured?
What is the minimum call-out and overtime rate?

Flagger certification rules are set by each state, so check your DOT.
Ask who is responsible for checking the setup each day and at night.
Get the plan approved early, because road permits can take longer than the work.
