THE OVERHANG CHECK
Will it fit?
What do you need?
Support length helps plan the setup. Legal projection is measured from a state-defined vehicle point. This tool keeps those two questions separate.
Physical support from the inside front wall to the bed/tailgate edge
FTIN
Open tailgate or support device; enter zero if none
FTIN

LEGAL-RULE MEASUREMENT
Measure from the taillamps to the extreme rear end of the load.
FTIN
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.
RULE REVIEW · CA△
UNSUPPORTED CARGO LENGTH
4 ft 6 inMarker equipment is triggered by the entered projection
California'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
MARKER STATUSRequired at entered projection
PROJECTION-RULE STATUSManual check required
DAYLIGHT REQUIREMENT
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.
MANUAL CHECKS THAT REMAIN
- Compare projection beyond the last point of support with two-thirds of wheelbase.
- Confirm total vehicle/load length and any special-load exception.

Kayaks
Short-bed pickups, open tailgates and the bed-extender question.
Lumber
Long boards, sheet goods and the trip home from the store.
Ladders
Rear projection, visibility and a stable support plan.
Canoes
Long hulls that may need a rack instead of unsupported bed carry.
