RouteAllUtah Oversize Load Signs, Flags And Lights
Sources Reviewed: October 23, 2026
Utah’s current R909-2 rule, effective March 16, 2026, separates nondivisible-load signs and flags in section 17 from travel and lighting in section 14. Check the current numbering rather than relying on older charts that place equipment in section 20.

When Does Utah Require The Load Sign?
For nondivisible loads, section 17 requires OVERSIZE LOAD signs above 10 feet wide, 14 feet 6 inches high or 105 feet long. The panel is 7 feet by 18 inches, yellow, with 10-inch black letters and 1⅝-inch strokes. These are alternative triggers. A tall load does not also have to exceed the width threshold before the sign requirement applies. Measure the loaded combination and keep each measurement beside its permit entry.
Where Are Utah Signs Mounted?
The front panel goes on the front bumper or cab top; the rear goes as far back as feasible without cargo obscuring it. If possible, its bottom is no higher than 5 feet above the road. Cover, remove or place signs face down outside oversized operation. The rule excepts longer combination vehicles. Do not assume a narrow mounting space allows a smaller transport panel; resolve the actual placement before dispatch.
Which Utah Loads Need Extremity Flags?
Section 17 requires red or orange flags above 10 feet wide or with front overhang above 3 feet or rear overhang above 4 feet. They must remain clean, intact and free to wave; LCVs are excepted. That paragraph does not give a flag dimension, so this guide does not substitute a pilot-equipment measurement. Check other applicable commercial-vehicle rules and permit conditions before choosing the cloth and bracket.
What Changes Outside Daylight Hours?
Section 14 adds extreme-width markers, with amber front/side and red rear; combinations above 92 feet need lights every 25 feet. It separately addresses overhang lamps and beacons. Compare those details with the actual configuration and Table 3’s travel limits. A correctly marked load may still be prohibited from non-daylight movement. Brief the crew using the current table and the permit, rather than treating an amber-light inventory as authorization to leave after dark.
How Can RouteAll Help Prepare The Utah Trip?
Import the issued permit into RouteAll and review its extracted road sequence while parked. Compare the first road, connecting junctions and final approach with the document, then share the reviewed route with the crew. Keep your equipment checklist beside that route review. RouteAll helps organize and navigate the permitted route; it does not inspect banners, certify flag placement or establish that a lighting setup complies with the permit.
Before You Roll
Match the measured load to the permit category. Inspect the actual front, rear and projecting points after securement. Resolve any unclear marking instruction with the issuing authority before dispatch, and revisit it when equipment or the load changes.
