Night Breakdown on a Flooded Shoulder
At 22:30 on an unlit rural road you are driving alone when the steering suddenly feels heavy and the vehicle pulls hard to the left. You stop and find the front left tyre is flat and partly shredded. The road has one lane in each direction with narrow, soft shoulders, and the left shoulder drops into a shallow flooded ditch. It is raining lightly and visibility is poor; traffic passes at speed. Your spare is inflated and the jack and wheel brace are in the boot. You are wearing a dark jacket. There is a torch in the glovebox and a reflective triangle in the boot. The nearest town is 6 km ahead.
1. Decide whether to change the tyre here or move the vehicle, and explain the reasoning using the hazards present.

The deciding question is whether the vehicle can be moved to a safer place without making things worse. A shredded tyre on the driven front wheel can be driven a short distance at low speed if the wheel rim is not cutting into the road and steering remains controllable, but the flooded ditch on the left and fast traffic make a shoulder change here dangerous.
My plan: switch on hazard lights immediately, put on the reflective triangle and torch, and drive slowly - walking pace - to the first place with a wider, firm, level shoulder or a lay-by, even if that is some hundreds of metres. If no such place exists within a short distance, I stop as far right as the firm shoulder allows, well away from the ditch, and do not attempt the change on soft ground where the jack will sink. I would not drive 6 km on a shredded tyre at normal speed; that risks rim, brake and steering damage and loss of control.
2. Describe the sequence you would follow to make the vehicle and yourself visible and to change the wheel safely.

First, hazard lights on and sidelights on so the vehicle is lit from both ends. Second, the reflective triangle placed on the road behind the vehicle - on a single-carriageway road roughly 50 metres back, and further if visibility is poor - but only if it is safe to walk to place it; I would carry the torch and wear the reflective material so approaching drivers see me before the triangle.
Third, passengers, if any, out of the vehicle and standing behind the barrier or well off the carriageway on the safe side, never between the vehicle and traffic. Fourth, loosen the wheel nuts slightly before jacking, chock the diagonally opposite wheel, jack on firm level ground, and never put any part of my body under the vehicle. Fifth, fit the spare, lower the vehicle, tighten nuts in a diagonal pattern, and check pressure at the first opportunity. Finally, drive below motorway-type speeds on a space-saver or temporary spare and get the damaged tyre replaced in town.
3. What would make you abandon the roadside repair entirely and call for assistance instead?

I would abandon the repair if any of the following held: the shoulder is too soft or sloped for the jack to sit safely; passing traffic is too close and fast to give me a safe working margin; it is too dark or wet to see and be seen adequately; the wheel nuts will not release with the tools I have; or the damage is more than a tyre - for example a bent rim, damaged suspension, or a brake line pulled loose, which the heavy steering and hard pull could indicate.
In any of those cases the risk of being struck while crouched beside the vehicle outweighs the inconvenience of waiting. I would stay in or beside the vehicle on the safe side with hazard lights on, keep the reflective triangle out, and call for recovery, giving the road name, direction of travel and nearest marker. Being able to describe exactly where I am matters as much as the repair itself.
