Inside a work zone, the person in high-visibility gear holding the STOP and SLOW paddle is the traffic control. A flagger's direction overrides signs and signals: the STOP face means a complete stop at the flagger's station, and movement resumes only on the SLOW face, at reduced speed, along the path shown.
The zone behind the flagger explains the strictness: workers on foot, machines crossing, and often a single lane serving both directions in alternation. Approaching one, slow early, stop where directed rather than alongside the flagger, and keep watching, because the instruction can change while you wait.
The tested mistake is treating the paddle as advisory, creeping past a STOP face, or resuming at normal speed on SLOW. Disobeying a flagger is penalized like running a signal, and in work zones many states penalize it harder.
This situation appears in 4 questions across 4 of our state banks, on Driver License practice tests. Start with your state:
A flagger directs traffic to stop while a nearby signal is green. Which instruction controls?
Why: Drivers must obey work-zone flaggers because a flagger's authority overrides conventional traffic-control devices. Therefore, the supported response is "The flagger's stop direction".
Every practice test explains its answers this way. Pick your state and take one free; no sign-up.
Choose your stateSTOP: a complete stop at the flagger's station until released. SLOW: proceed at reduced speed along the indicated path. There is no third reading.
Yes. Within the zone, the flagger's direction takes precedence over posted controls, which is the specific fact written tests check.
Half the road is occupied by the work, so one lane serves both directions in turns, metered by flaggers at each end. The STOP you are given is the other direction's SLOW.
Slow well before it, stop where the paddle and hand signals direct, leave room ahead, and stay attentive; the release can come at any moment, or be withdrawn.
Disobeying a flagger is treated like disobeying a signal, and many states raise fines for violations in work zones, especially with workers present. The exact scheme is each state's own.
