Mandatory Signs (Circular)

Mandatory signs tell drivers what they MUST or MUST NOT do. They are circular in shape. Circular signs with a red border are prohibitory (e.g., 'No Entry', 'Speed Limit 50', 'No Overtaking'). Circular signs with a blue background indicate positive commands (e.g., 'Turn Left Only', 'Keep Left').

Violating circular mandatory signs is a punishable offense under the Road Transport Act of Bangladesh.

Cautionary signs warn road users of hazards ahead. They are triangular with a red border and a white background (e.g., 'Sharp Bend Ahead', 'Pedestrian Crossing', 'Narrow Bridge'). Drivers should reduce speed immediately when spotting a triangular sign.
