Police Directions and Hand Signals: When a Person Overrides the Machine
The hierarchy of control
When a police officer is directing traffic, the officer's signals override traffic lights, signs and road markings. If an officer waves you through a red light, you proceed carefully; if an officer raises a hand to stop you, you stop even on green.
Common signals to recognise
- Stop: arm raised with the palm facing you, or a whistle with an outstretched arm.
- Proceed: arm beckoned toward you, or a wave in the direction you should travel.
- Slow down: arm moved up and down with the palm downward.
- Turn: arm extended in the direction of the intended turn.
- Pull over: an officer points at you and then indicates the roadside.
Hand signals from other drivers matter too: an outstretched right arm means turning right; a left arm out of the window rotating means slowing; an arm moving up and down means slowing further. A driver's arm bent upward often indicates an intention to turn right in some conventions - always confirm with indicators and position.
Obeying directions safely
Even when waved on, check for hazards before moving. Do not argue at the roadside; comply and raise concerns later through the proper channel. Keep your hands visible, stay in the vehicle unless asked to step out, and produce documents when requested.
Traps
Questions often test whether you follow the light or the officer - the officer always wins. Another trap is misreading a “slow down” gesture as “stop”, or assuming a signal applies to all traffic when it is aimed at one lane.
Rule of thumb: Officer first, signals second, signs third, markings fourth. And always confirm the gesture is aimed at you before acting.
Worked example: An officer holds up a palm toward your lane while your light is green. You stop behind the line and wait; the officer's signal overrides the green light.
First Aid and Emergency Response: Acting Calmly and Correctly
Priorities at an emergency
Use a simple sequence: make the scene safe, assess responsiveness and breathing, call emergency services, then give aid within your training. Protect yourself first - a second casualty helps no one. Switch off engines, warn traffic, and do not smoke near fuel.
The primary check
Gently check for response. If unresponsive and not breathing normally, start chest compressions at a steady rate (around 100–120 per minute) with the heel of the hand in the centre of the chest, and continue until help arrives or the casualty recovers. If trained and willing, combine with rescue breaths. If breathing but unconscious, place in the recovery position unless a spinal injury is suspected.
Bleeding, burns and shock
Apply firm direct pressure to control bleeding, using a clean pad. Cool burns with clean, cool water for a sustained period and do not remove stuck clothing. Keep casualties warm and still to limit shock. Never give food or drink to an injured or drowsy person.
Moving casualties
Do not move an injured person unless there is immediate danger such as fire, or to prevent further injury. Suspect spinal injury after any significant impact.
Traps
Questions often reward the safest action, not the most heroic. Calling emergency services and securing the scene can be the best answer. Another trap is removing a motorcyclist's helmet unnecessarily.
Rule of thumb: Safety, Response, Call, Aid - in that order, every time.
Worked example: You find a motorcyclist conscious and breathing after a fall. Leave the helmet on, keep them still and warm, warn traffic, and call emergency services - moving them or removing the helmet risks worsening spinal injury.
