This traffic sign is displayed on the right-hand kerbside. What does it indicate?

You answered correctly. This traffic sign means the start of an absolute no-stopping zone. When you see this sign on the right-hand side of the street, stopping and parking are both not allowed at all, starting from where the sign is placed. The arrow indicates the direction in which the no-stopping rule applies. This rule is strict and applies along the entire stretch until an ending sign is shown. Remember, violating this rule can result in fines or your car being towed.
