The literal meaning is universal. The metaphorical 'dilapidated building/vehicle' sense is more common in British, Australian, and New Zealand English. 'Rat-trap' for a type of bicycle pedal is a global cycling term.
Connotations
In both varieties, the connotations for the metaphorical sense are strongly negative, suggesting discomfort, danger, and poor condition.
