Length limitBangladesh
1. Length limit
A length limit is a restriction that prohibits vehicles or vehicle combinations longer than a specified maximum length from entering a road or area. The stated length normally includes the complete vehicle combination and any load where national rules specify this.
Length restrictions are commonly used where long vehicles cannot safely negotiate narrow streets, tight bends, bridges, tunnels or other constrained road layouts. Drivers whose vehicle exceeds the indicated limit must use another permitted route.
Why might a road have a vehicle-length restriction in Bangladesh?
The Road Sign Manual describes A13 as prohibiting vehicles over the length shown in metres, for example where road geometry is too tight for longer vehicles. Read the actual sign and choose a permitted alternative before entering the restriction.
Vehicles longer than indicated prohibited.
English • Traffic sign A13 • Maximum length: 10 m. Do not proceed beyond this sign if your vehicle exceeds 10 metres in length.
বাংলা • A13 • সর্বোচ্চ দৈর্ঘ্য: ১০ মিটার. যানবাহনের দৈর্ঘ্য ১০ মিটারের বেশি হলে এই চিহ্নের পর যাবেন না।

What if your vehicle combination exceeds a signed length limit in Bangladesh?
Choose another permitted route before entering the restricted section. Do not assume a wide carriageway is suitable: long vehicles need room for their swept path, particularly at sharp bends, junctions and roundabouts.
