1. Height limit
A height limit prohibits vehicles whose total height exceeds the value shown from entering or passing a road section, bridge, tunnel, gateway or other structure. The vehicle’s height includes its load and any equipment attached above it.
Drivers of high vehicles must know their exact height, observe advance warnings and use an alternative route when necessary. They should never rely only on visual judgement or attempt to pass beneath a structure when safe clearance is uncertain.
How should you read a low-bridge height restriction in Bangladesh?
The Road Sign Manual distinguishes A14, the regulatory maximum-height sign, from B20, Height Limit Ahead. Read the displayed measurement and check the whole vehicle with its load and roof equipment. A warning of an obstruction and a prohibition on over-height vehicles serve different purposes.
Vehicles higher than indicated prohibited.
English • Traffic sign A14 • Maximum height: 4.4 m. Do not proceed beyond this sign if the height of your vehicle and load exceeds 4.4 m.
বাংলা • A14 • সর্বোচ্চ উচ্চতা: ৪.৪ মিটার. গাড়ি ও বোঝার উচ্চতা ৪.৪ মিটারের বেশি হলে এই চিহ্নের পর যাবেন না।

Does a roof load count when checking vehicle height in Bangladesh?
Yes for practical clearance: measure the vehicle at its highest point with its load and fitted accessories, such as a roof box, bicycle or roof rack. Check the local legal measurement rules as well; an empty vehicle’s registered height is not enough when equipment has been added.
What should you do if your vehicle is too high for a bridge or tunnel in Bangladesh?
Do not try to squeeze under the structure. Use the signed alternative route and, if you are already close to the obstruction, stop where safe and seek traffic-control assistance rather than reversing unpredictably into moving traffic.
