Notes in the source (in Japanese)
軸重は、荷の重さだけでなく「重さ × 軸からの距離」(置き場所)で決まる。
前へ寄せすぎると前軸が超える。後ろへ寄せすぎると後軸が超え、前輪が浮く(ハンドルが効かなくなる)。
重い荷ほど軸の近くへ置く。
荷だけでは合わない。空車重量とその重心を先に置いてから、荷を足す。
総重量 20 t、軸重 10 t、輪荷重 5 t、長さ 12 m、幅 2.5 m、高さ 3.8 m(指定道路は 4.1 m)。1 つでも超えたら特殊車両で、通行許可が要る。総重量は高速自動車国道・重さ指定道路で最大 25 t(長さ・軸距による)。出典:車両制限令 第 3 条/国土交通省「道の相談室」一般的制限値(https://www.mlit.go.jp/road/soudan/soudan_09_02.html 、取得 2026-09-29)。
