how should a trailers safety chains be attached to the towing vehicle?\na crisscrossed under the trailer coupler\nb crisscrossed over the trailer coupler\nc under the body of the vehicle and attached to the front bumper\nd over the trailer coupler and attached to the rear tires
Answer
Brief Explanations:
Safety chains on a trailer are typically attached by criss - crossing them under the trailer coupler. This creates a sort of 'basket' to catch the coupler if it detaches, preventing the trailer from completely separating from the towing vehicle.
Answer:
A. crisscrossed under the trailer coupler
