In my view, the Driver had failed to keep a proper lookout as he was driving along the side road even though he had the right of way until he reached the junction with the main road. If he had kept a proper lookout, he would have noticed the Cyclist on his left. There is no suggestion that even if he had noticed the Cyclist, it would have been too late for him to stop or to swerve to avoid the Cyclist. Furthermore, if the Driver had noticed the Cyclist, he would have been under a duty to sound the horn of the truck to warn the Cyclist of the approaching truck, especially if it appeared that the Cyclist might not have noticed the presence of the truck. Consequently, as the Driver did not notice the Cyclist, he continued driving towards the junction with the main road and the Cyclist collided into the truck, not at that junction, but at the intersection between the footpath and the side road.
