Ku United States, zizindikiro zoyimitsa zili ndi kukula kwa 750 mm kudutsa moyang'anizana ndi ma octagon ofiira, wokhala ndi malire oyera a 20 mm. Zilembo zazikuluzikulu zokhala ndi zipewa zing'onozing'ono zomwe zimapanga nthanoyo ndi 250mm. Zizindikiro zazikulu za 900 mm (35 in) zokhala ndi nthano ya 300 mm (12 mu) ndi 25 mm (⅞ in) amagwiritsidwa ntchito pama msewu a multilane.
