What is the effect of the cornering characteristics of a combination vehicle (car towing a caravan) when taking a turn?

You answered correctly. When a car is towing a caravan, the combination's cornering characteristics differ from a single car. The caravan can jut out to the side (option 1), especially on tight bends, because the rear of the trailer swings outward (off-tracking). It can also cut the corner (option 2), meaning the caravan's path may be tighter than the car’s path. The trailer generally does not follow the exact track of the towing vehicle (option 3 is incorrect). Understanding this helps drivers take wider turns and watch for obstacles on both the inside and outside of corners when towing a trailer or caravan.
