Are you allowed to stop at this point on the carriageway?

In the photo you are driving in a town along a street which bends to the left; the lane is narrow, a double solid line runs along the centre of the road, and there is a pavement on the right. You must not stop on the roadway at this point. The answer is: no.

The Road Traffic Act prohibits stopping a vehicle on the roadway alongside a solid line and near its end points if this would force other drivers of multi-track vehicles to drive onto this line. The lane in the photo is so narrow that a car behind you could not go around your stationary car without driving onto the double solid line, and crossing it is prohibited - so stopping here is ruled out. There is also the bend: stopping and parking are allowed only where the vehicle is visible from a sufficient distance and does not obstruct traffic, and after a bend a stationary car appears suddenly. If you have to stop, you drive on to a place with a broken line and enough width. You may drive onto the pavement itself with the wheels on one side only if you meet the conditions set out in the Act, among others when the pavement is at least 1.5 m wide and you will not obstruct pedestrians.
