Regulations change. This page summarises published Arizona rules as reviewed October 2026 and is not legal advice; the conditions printed on your permit control. Note: No single statewide daytime escort width threshold in rules: Department sets escorts per permit and route (R17-6-305; Table 4 of R17-6-412). escortOneWidthFt=14 reflects Table 4 entries for I-8/I-10/I-40 (Over 14-16 ft = R or F/R); many other routes require F/R from 12 ft. Two-escort width left null because it varies by route. Height pole 15 ft is from the night/weekend rule only. Overhang over 20 ft needs escort. Class A permit up to 14 ft wide, 16 ft high, 120 ft long, 250,000 lb. Permit office phone not found on fetched pages. Class A fees: oversize single-trip $15, OS/OW single-trip $75.
