Kansas Oversize Load Signs, Flags And Lights

What Does Kansas Highway Patrol Say About Banners?

KHP’s commercial-vehicle FAQ says permitted vehicles exceeding width or length limits display OVERSIZE LOAD while operating in Kansas, and overweight-only vehicles do not display that sign.

Classify the entire loaded combination before applying that distinction. A heavy load on a long specialty trailer may not be overweight-only even if the freight itself fits legal width. Retain the vehicle measurements with the permit so an equipment exception is not carried over to a different trailer.

Where Are Kansas Sign Measurements Published?

The Secretary of State’s 2022 Volume 3, K.A.R. 36-1-35(k), defines the load sign as at least 7 feet by 18 inches, with 10-inch black letters and at least a 1⅖-inch stroke on yellow. That is a dated compilation, not independent confirmation that no later amendment exists.

Bring the exact definition to the equipment supplier and ask the permit office to confirm the current specification before relying on the older book. Do not casually round the stroke to a familiar size from a neighboring state.

Why Is The Overweight-Only Distinction Flagged Here?

The 2022 K.A.R. 36-1-36(s) text refers to signs for oversize and overweight loads, while its removal sentence and the KHP FAQ distinguish legal-dimension operation. The current rules website did not provide an extractable consolidated rule during this review.

This is a source conflict to resolve, not a reason to choose whichever instruction requires less equipment. Ask KDOT/KHP about the actual permit and legal-dimension overweight case. Keep any clarification with the movement records and preserve its scope instead of treating it as blanket permission for future assignments.

What Flag Difference Does KHP Explain?

KHP says projections more than 4 feet rearward or 4 inches sideways require flags, contrasting 18-inch red/fluorescent-orange flags under federal regulation with 12-inch red flags under state law. Its FAQ cites 49 CFR 393.87 and K.S.A. 8-1715.

Determine which rules cover the operation before choosing a flag inventory. A state flag minimum is not a federal exemption. For lights, read the projecting-load provision and issued permit separately; a flag-size answer does not settle nighttime lamps or an escort’s warning-light arrangement.

How Can RouteAll Help With This Movement?

Import the Kansas permit into RouteAll and review the extracted route after resolving the equipment-source conflict with the authority. Keep that clarification with the original document. RouteAll does not settle the legal interpretation, validate a dated sign specification or replace a warning-device inspection. Get RouteAll For Permit Route Review.

Before You Roll

Resolve the current sign instruction for the actual permit, then confirm dimensions and federal/state flag scope. Keep a source date beside older specifications. Finish the nighttime projection and escort-light checks independently rather than inferring them from a banner answer.
