it depends on the d.o.t. officer. some signs are obvious. like a ripped area, shredding. fraying, sewing coming loose, e.t.c. remember any EXTRA securement, even though EXTRA, if any defect you will be in violation. so if you have any defective straps, do not think you can use as an extra level of safety. d.o.t. does not look at you being safety conscious. they look at you as a ticket & fine!
