The statistics on the automotive industry include a section called Car/truck, and all data in this section are either Car or LTR. What does LTR mean in this case? Thank you very much for your help.
Please tell us where you saw this. In what context? Are you sure it hasn't been spelled out in full somewhere before this in or on wherever you saw this sentence?
There are numerous LTRs listed here: What does LTR stand for?
I'm guessing it could be 'Light Trailer' or possibly 'Load to Ride.'
