Delaware splits its rules by road class. On Interstate and federal-aid primary routes (§ 4503) it tracks the federal 20,000 / 34,000 / 80,000. Everywhere else (§ 4502) axle limits are more generous at 22,400 lb, but gross weight is capped by axle count — 40,000 lb for two axles, 73,280 for four — and by the manufacturer’s GVWR in every case.
