A pilot car is used in a work zone. What is the pilot car's primary function?
Answer: To lead vehicles through the work zone at a safe speed
A pilot car (or pace car) leads a group of vehicles through the work zone at a controlled, safe speed, guiding them past hazards.
Which of the following actions is PROHIBITED for a flagger during active flagging duty?
Answer: Using a personal cell phone for non-work communication
Using a personal cell phone for non-work communication is prohibited during active flagging because it creates dangerous distractions from traffic control duties.
What does a 'flagger ahead' (W20-7a) sign alert drivers to do?
Answer: Be prepared to stop or slow as directed by a flagger
The W20-7a 'Flagger' warning sign tells drivers that a flagger is controlling traffic ahead and they should be prepared to stop or reduce speed.
When flagging on a multi-lane road, which lane should be closed FIRST to create a safe work zone?
Answer: The lane nearest to the work activity
The lane directly adjacent to the work activity is closed first to protect workers, then additional lanes are closed as needed working outward.
A flagger notices a vehicle approaching at high speed and shows no signs of slowing. What is the SAFEST immediate action?
Answer: Move quickly to an escape route away from the vehicle's path
If a vehicle fails to respond, the flagger's highest priority is self-preservation — moving to a predetermined escape route away from the vehicle's path.
How long should a flagger typically hold traffic before releasing it in a standard one-lane operation without a pilot car?
Answer: As long as needed until the opposing queue clears, up to a reasonable maximum
Flaggers should hold traffic until the opposing direction has cleared the work zone, but should not hold any direction unreasonably long, typically no more than a few minutes.
Which personal protective equipment (PPE) item is ALWAYS required for California flaggers regardless of the time of day?
Answer: High-visibility safety vest meeting ANSI/ISEA standards
A high-visibility safety vest meeting ANSI/ISEA Class 2 or higher standards is always required for flaggers to ensure they are seen by approaching drivers.
