Answer

At least 45 metres (147 feet) behind the vehicle on the same side of the road
According to The Highway Code (Rule 274), when a vehicle breaks down on a road other than a motorway, an advance warning triangle should be placed on the same side of the road at least 45 metres (147 feet) behind the vehicle to give approaching drivers clear advance warning of the hazard.

Step-by-Step Solution

1
Identify the road type and applicable breakdown safety rules
The breakdown is on a rural single carriageway, where using an advance warning triangle is permitted and recommended.
Highway Code Rule 274 permits warning triangles on standard roads but strictly forbids them on motorways.
2
Determine the required distance and placement orientation
Position the warning triangle at least 45 metres (147 feet) behind the broken-down vehicle on the same side of the road.
This distance gives following drivers sufficient time and braking distance to slow down safely.
