Challenge
Under-signs are small and often read as 'extra info, ignorable' — exactly wrong, because they can completely flip a prohibition (exemption) or tie it to time (time window). And any practice material using '600 m' as an example teaches you a number that doesn't exist in this book — the exam designer tests the book's number, not a generic textbook figure.

The model
Give a further explanation, restrict the sign to a group (bare symbol), or exempt a group ('uitgezonderd' + symbol). At E-parking signs with times, the ban applies only within that time window. And the book's distance example is 500 metres — not 600 — confirmed on both p.47 and p.252.

Core
Under-signs do not exist independently: the law opens with 'under-signs placed under traffic signs' — without the main sign above it, an under-sign has no meaning. What exactly the under-sign does depends on the precise text and symbol. If only a symbol appears (no text), that RESTRICTS the main sign to the indicated group or behaviour — for example a truck silhouette restricting a ban to trucks only. If the word 'uitgezonderd' (excepted) appears with a symbol, it flips around: that group is instead EXEMPTED from the ban — the opposite mechanism, with almost the same layout. At E-parking signs (E4 through E8, E12, E13) with days or hours on the under-sign, the order or prohibition applies only within that time window — outside those hours, parking or stopping is simply allowed. The book shows a concrete example: 'Monday through Friday from 8 to 18 hours and Saturday and Sunday from 6 to 24 hours' (Book p.252). For distance under-signs the book consistently uses 500 metres, in two different applications: '500 m' without arrows means 'applies over 500 metres from here', while '↑500 m↑' with arrows on both sides means 'applies for the coming 500 metres' — subtly different wording for two slightly different situations, but the same book figure: 500, never 600.

Why it matters
Whoever reads 'uitgezonderd' as a restriction instead of an exemption wrongly drives onto a prohibited road — or wrongly stops where it's actually allowed. Whoever ignores a time window risks a fine outside the sign's hours, or wrongly parks within the prohibited hours. And whoever remembers '600 metres' as the book figure fails an exam question that literally tests the book's number.

Frequently asked questions
‘An under-sign with the word 'uitgezonderd' (excepted) plus a bicycle symbol means the traffic sign applies TO cyclists specifically, and only to them’ – is that true?
No. 'uitgezonderd' + symbol = the sign does NOT apply to that group (exemption); a bare symbol without 'uitgezonderd' restricts the sign TO that group instead
‘An under-sign with a symbol applies on its own, even if the main sign above it has been removed or is illegible’ – is that true?
No. An under-sign contains a further explanation OF THE TRAFFIC SIGN; without a main sign an under-sign has no independent effect
‘The under-signs '500 m' and '↑500 m↑' mean exactly the same thing: both simply indicate the distance to the main sign’ – is that true?
No. '500 m' (no arrows) = applies over 500 metres from here; '↑500 m↑' (with arrows) = applies for the coming 500 metres — two different applications of the same number, not synonyms
‘If an under-sign at an E-parking sign shows days and hours, the parking ban still applies all week — the under-sign is just extra information’ – is that true?
No. If an under-sign at E4 through E8, E12 or E13 shows days or hours, the orders/prohibitions apply ONLY during those days or hours — outside that window the ban does not apply
‘If an under-sign shows two time windows, the widest window applies on every day of the week’ – is that true?
No. Each time window belongs to the days written before it; outside those days and hours the sign does not apply (book example 'Mon-Fri 08-18h Sat/Sun 06-24h').
