What the exam asks about this sign

The exam asks what 'uitgezonderd' (except) does: the named group (here riders) need not obey the sign; for everyone else it still applies. Trap: candidates confuse it with OB1, where the sign applies to riders only; the word 'uitgezonderd' is the key.

Often confused with

• The sign applies only to horse riders OB1 — Riders only: the reverse.
• 'Except heavy goods vehicle' sub-panel OB61 — Except lorries: the same logic for another group.
• Closed to riders C9 — Closed to riders: the sign this often hangs under.
