    Position a reflective warning triangle at least 45 metres behind your vehicle
  2. Switch on your hazard warning lights and keep sidelights illuminated if it is darkAnswer
  3. C
    Flash your headlights continuously to alert drivers approaching in the left lane
  4. D
    Stand behind the rear bumper wearing high-visibility clothing to signal passing traffic

Answer

Switch on your hazard warning lights and keep sidelights illuminated if it is dark
According to the Highway Code (Rule 274), if your vehicle breaks down on the motorway hard shoulder, you should switch on your hazard warning lights to alert other drivers. If visibility is poor or it is dark, you should also leave your sidelights on. You must never attempt to place a warning triangle on a motorway.

Step-by-Step Solution

1
Identify the required warning signal for stationary vehicles on a motorway
Hazard warning lights must be used to warn other drivers that the vehicle is temporarily obstructing the hard shoulder or creating a hazard.
Highway Code Rule 274 mandates the use of hazard warning lights in breakdown situations.
2
Identify prohibited warning devices on high-speed roads
Warning triangles must never be used on motorways.
Deploying warning triangles on high-speed roads exposes the driver to extreme danger from fast-moving traffic.
3
Select the correct and lawful action
Activate hazard warning lights (and sidelights in darkness or poor visibility) and vacate the vehicle to the verge.
This complies with safety protocols while keeping vehicle occupants protected.
