Mandatory signs

A mandatory sign is a traffic sign that tells drivers what they must do. Instead of prohibiting actions, these signs impose obligations such as following a specific direction, using a particular lane, or keeping a minimum speed. Their purpose is to guide traffic safely and efficiently by ensuring that all road users follow the same required behaviour in places where it is necessary for order and safety.

How are compulsory instructions shown in Bangladesh?

Mandatory regulatory signs require an action, such as following the indicated direction. STOP is also an instruction, not ordinary guidance.

What does a mandatory-direction sign require in Bangladesh?

Where a compulsory-direction sign is installed in Bangladesh, follow only the arrow direction or permitted combination of directions. The restriction applies at the location or movement it regulates; it is not an instruction to ignore other traffic controls.

Does a mandatory-direction sign give me priority over pedestrians in Bangladesh?

No. It tells you which way to move, not who goes first. Check traffic lights, other priority signs, pedestrians and cyclists, and give way when required before completing the manoeuvre.
