The applies to moped riders plate is attached directly below a main sign to narrow its effect to mopeds of the category shown, such as bromfiets, snorfiets or both. It may clarify whether a route, turn or restriction concerns only these vehicles, for example at separate moped tracks or on mixed use carriageways. Cyclists and other vehicles follow the basic rule or any plate that refers to their class, so it is important to read the combination of signs.
This supplementary plate shows that the rule on the main sign applies specifically to moped riders, often including both bromfiets and snorfiets categories as defined locally. It makes clear that these motorised two wheelers must follow the indicated prohibition or obligation, while cyclists and other traffic only have to comply if they are named on another plate or covered by the general rule.

The main purpose of the OB-03 sign is to clarify that a specific traffic rule, such as a speed limit or a prohibited area, applies only to moped riders. It ensures that drivers of other vehicles, like cars or bicycles, understand that the restriction or direction does not concern them.
If you are riding a moped (bromfiets or snorfiets), you must adhere to the rule indicated by the main sign this OB-03 sign is supplementing. If you are driving another vehicle, you can usually ignore the rule directly associated with this sign, but always remain aware of your surroundings and other traffic signs.
A common trap is assuming the sign OB-03 exempts mopeds. However, it actually *confirms* that the main sign's restriction *applies* to mopeds. Learners can also be confused if there are additional plates specifying 'engine on' or 'engine off' conditions for mopeds, which must also be obeyed.
If you see an 'Uitgezonderd' sign below the OB-03 sign, it means the opposite: the rule indicated by the main sign does *not* apply to mopeds. This is a crucial detail to remember for your theory exam. Always read all plates carefully.
No, the OB-03 sign specifically targets mopeds. Cyclists are typically not affected by rules indicated by this sign unless a different supplementary sign explicitly states otherwise. The sign is meant to differentiate the rules for mopeds from those for bicycles and other vehicles.
