How should you behave upon missing an exit on a road with heightened traffic?

In the photo you can see, from the cab, the back of a lorry driving along a wide road, with a slip road branching off to the right and a speed limit of 40 km/h. When you miss your exit on a road with heavy traffic, you drive on to a place where you can stop safely - answer C.

The Road Traffic Act requires you to be careful and to avoid actions that could cause danger, and you may stop a vehicle only where it is clearly visible and does not obstruct traffic. Stopping the bus before the traffic lights to ask pedestrians the way (answer A) blocks traffic and risks a rear-end collision. Checking the map while driving (answer B) takes your eyes off the road, and using a hand-held phone is prohibited. A missed exit means only a few extra kilometres - you calmly drive to the nearest car park or lay-by, check the route and go back. Reversing and making a U-turn on a slip road is dangerous, and reversing on a motorway and an expressway is prohibited.
