Question

DentroTest · Accepted Answer

The correct answer is that drivers must stop immediately.  According to traffic regulations, acoustic signals (whistle) from officers have specific meanings to avoid confusion: Short and frequent blows: Order vehicles to stop. Long blow: Orders to resume driving (continue). Remember that signals from traffic officers are at the top of the signaling hierarchy and take priority over traffic lights and other rules.
