Final answer:
Train-vehicle accidents predominantly occur at controlled crossings
Step-by-step explanation:
Over half of train-vehicle accidents happen at controlled crossings where a train track intersects with a road and there are warning signs, gates, and signals in place to regulate traffic. These accidents often occur due to drivers not following the warning signals or attempting to cross the tracks when a train is approaching.
Train-vehicle accidents are less likely to occur at train stations because there are designated areas where vehicles can safely pick up or drop off passengers, and there are usually barriers preventing access to the train tracks.
Therefore, the correct answer is controlled crossings as the location where over half of train-vehicle accidents take place.
