The OB-06 road sign, often referred to as 'Motorcycles only' or 'MC only', is an information sign specifically designating that the subsequent instruction or restriction applies solely to motorcyclists. You will encounter this sign when a particular traffic rule or routing is intended exclusively for motorcycles, perhaps to manage traffic flow in urban areas or at junctions. While driving a car, you can generally ignore the instruction that follows this sign, as it does not pertain to you.

The motorcycle plate is mounted directly below a main traffic sign to limit the rule to solo motorcycles, and sometimes motorcycles with sidecars where indicated. It is often used in busy urban streets, near residential zones, or on special motorcycle routes to manage noise, safety, and flow. The plate does not automatically extend the rule to passenger cars, lorries, or buses.
This additional plate indicates that the rule on the main sign applies specifically to motorcycles. Riders must obey the instruction or restriction, such as a turn ban, access rule, or lane allocation that targets powered two-wheelers. Other drivers should be aware that motorcycle movements may be channelled differently and anticipate lane changes or alternative routes taken by these vehicles.

The OB-06 sign serves to inform drivers that the traffic instruction or restriction immediately following it is applicable only to motorcycles. It's a way to segment rules for different vehicle types, ensuring motorcyclists follow specific guidance while other vehicles are unaffected.
If you are driving a car, you should understand that the OB-06 sign means the subsequent sign's message does not apply to you. For instance, if the next sign indicates a turn ban for motorcycles, you are not bound by it unless a different sign indicates otherwise for your vehicle category.
A common trap is assuming the sign means motorcycles are *allowed* somewhere; it actually means subsequent rules *only* apply to them. Learners might also mistakenly think that if a rule is only for motorcyclists, it automatically allows them to do something else, which isn't always the case. Always check for other signs.
Yes, the OB-06 sign can be used with various instructions or restrictions. This could include routing mandates, turn prohibitions, speed limits, or even time-of-day restrictions specifically for motorcycles. The key is that the main instruction is exclusively for this vehicle type.
The note 'Uitgezonderd' means 'excepted'. If you saw a sign with OB-06 and then 'Uitgezonderd' followed by 'motorcyclists', it would imply that motorcycles *are* excepted from the main sign's instruction, meaning the rule *would* apply to other vehicles. However, OB-06 itself means the opposite: the rule applies *only* to motorcyclists.
