What a Difference a Shape Makes!

Many drivers get confused when they see these two signs
— they often don’t know or mix up their meaning!
Here’s the explanation without bold text:
—
Round blue traffic sign with a white arrow → mandatory sign
* This means it is compulsory to follow the direction shown.
* For example, a right-pointing arrow on a round blue sign means you must turn right.
* These signs are part of the traffic rules and must be followed.
Examples:
Mandatory straight ahead
Mandatory turn left
—
Square or rectangular blue sign with a white arrow → information sign
* These are informative, not mandatory.
* They usually indicate the recommended direction, traffic flow, or preferred routes.
* Not following them does not result in a fine, unless there’s another sign that makes it compulsory.
Examples:
Recommended direction
Preferred route

Summary:
* Round = You must follow the direction (mandatory)
* Square/Rectangle = Just informational (not mandatory)
