What manoeuvre is the passenger car driver making

Explicación

The truck is travelling in the right lane as part of the traffic stream, with no hazard lights, warning triangle, or obstruction indicating a stationary breakdown. The sedan's path moves into the adjacent same-direction lane to pass the truck and continue ahead of it, which makes the manoeuvre overtaking rather than going around a stationary obstacle. Because the path continues along the same road instead of leaving it, the manoeuvre is not a turn.
