THE OVERHANG CHECK
Support length helps plan the setup. Legal projection is measured from a state-defined vehicle point. This tool keeps those two questions separate.
Do not subtract a tailgate or bed extender unless the cited rule uses that point.
Planning information only — not legal advice. Secure every load and confirm current rules, vehicle limits, cargo guidance, axle position, total length, and exceptions.
UNSUPPORTED CARGO LENGTH
4 ft 6 inCalifornia's maximum rear projection depends on the last point of support and wheelbase. Any projecting load still needs a manual maximum-length check.
Physical support7 ft 6 in
Cargo length12 ft 0 in
Legal projection4 ft 6 in
Marker threshold≥ 4 ft
At 4 ft or more behind the taillamps: a solid red or fluorescent-orange flag at least 18 in square; wider loads can require two flags.
No form, account or personal information is required. Opening the checklist only records anonymous interest in manual-review guidance.
Matched to this result; product links do not change the legal measurement.
The retailer lists an 18 × 18 in true-red flag. Check whether one or two flags, placement and attachment are required for this load.
