Locking system for door on over-the-road vehicle

In combination:

• an over-the-road vehicle comprising a frame bounding a cargo space and at least one door that is movable between closed and open positions to selectively block and allow access to the cargo space, the at least one door comprising a first door with inside and outside surfaces, and a peripheral edge having a thickness dimension between the inside and outside surfaces;
• the over-the-road vehicle configured so that with the first door in the closed position a gap is formed between one portion of the peripheral edge of the first door and one of:
• a) a second door;
• and b) the vehicle frame;
• a first locking assembly connected to the first door;
• and
• a second locking assembly connected to the one of:
• a) the second door;
• and b) the vehicle frame;
• a first portion of at least one of the first and second locking assemblies projecting through the gap to beyond the outside surface of the first door to cooperate with a locking device that acts between the first and second locking assemblies to maintain the first door in the closed position,
• wherein a region of the first portion of at least one of the first and second locking assemblies is locally strengthened in a manner to resist severance or bending of the region of the at least one of the first and second locking assemblies so as to allow the first door to be moved from the closed position towards the open position to permit access to the cargo space.
