Regulations change. This page summarises published Indiana rules as reviewed October 2026 and is not legal advice; the conditions printed on your permit control. Note: M-204 text extracted from PDF is partly garbled; the '14'4" and 17"' range is most likely 14'4" to 17 ft. On divided highways only a single rear escort is specified even above 14'4", so the two-escort width applies mainly to non-divided roads. Legal width 8'6". 'Last weekday preceding' means Friday noon for Monday holidays (whole weekend covered).
