If the symbol on the sign applies to your vehicle or group, you should follow the indicated route.

The F31 sign, often called a 'designated user route' sign, means that the route shown is recommended or designated for a specific type of vehicle or road user, indicated by the symbol on the sign. Its purpose is to guide these specific users along a more suitable or safer path, like a bypass.
You only have to follow the route indicated by the F31 sign if the symbol on the sign matches your vehicle type or road user group. If the sign is, for example, for heavy goods vehicles and you are driving a car, you do not need to follow that specific route unless other signs instruct you to do so.
If the symbol on the F31 sign does not apply to your vehicle or group, you should generally treat the sign as purely informational. This means you can continue on your current path, but always be aware that other types of vehicles or users might be directed along the indicated route, so be vigilant.
While the F31 sign primarily indicates a recommended or suitable route, by guiding specific vehicles away, it implicitly helps to keep certain roads clearer for other traffic. However, it's an informational and guiding sign rather than a prohibitory one like a 'No Entry' sign. Always check other signs for any prohibitions.
A common trap is assuming the sign applies to all vehicles, or that the indicated route is mandatory for everyone. Remember to check the symbol carefully. Another trap is forgetting that even if the sign doesn't apply to you, you should still be aware of the traffic it directs and drive defensively.
