One pole, many signs: how to read them

A pole with three or four signs stacked on it looks intimidating, but there's a fixed grammar: the sign at the top gives the order, and every plate below it qualifies that order - when it applies, in which direction, and who's exempt. Read top to bottom and any pole makes sense.

01

The reading order

  1. Start at the top: the biggest sign (a red circle, blue circle or triangle) is the rule itself - no entry, no waiting, a speed limit.
  2. Then read each plate below in turn: white plates with times ('Mon-Sat 9am-5pm') say WHEN the rule applies; outside those hours it doesn't.
  3. Arrows point along the kerb: the restriction runs in the arrow's direction from where you're standing. Two plates with opposite arrows mean different rules on each side of the pole.
  4. Exemption plates ('Except for access', 'Except buses', 'Except for loading') say who may ignore the rule - and only for that purpose.
  5. 'At any time' means exactly that - the rule never switches off, like a double yellow line.

  • The no-entry disc at the top is the headline order: vehicles must not enter this street from here.
  • The yellow plates beneath carry waiting restrictions: 'At any time' with a left arrow (a permanent restriction running to the left) and 'Mon-Sat 9am-5pm' with a right arrow (a daytime-only restriction running right).
  • The white 'No loading Mon-Fri 9am-5pm' plate adds a loading ban - during those hours you can't even stop to unload on that side.
  • So the same pole tells a driver: don't enter here; to the left, never wait; to the right, don't wait during shop hours; and don't load on weekday working hours.

The plates you'll meet most

PlateWhat it does
Times ('Mon-Fri 8am-6.30pm')Limits the rule to those hours - outside them, it's off
'At any time'The rule never switches off
Arrows (← →)The direction along the kerb the restriction runs
'Except for access'Through-traffic banned; genuine visits allowed
'Except buses' / 'Except for loading'Named exemptions only - everyone else, the rule stands
'Zone' / 'Zone ENDS'The rule covers a whole area, set at its entry sign

Plates never stand alone - each one qualifies the sign (or line) it's mounted with.

Quick answers

Which sign wins if a pole carries several?
They don't compete - the top sign is the rule, and the plates below qualify it. Read them as one sentence: rule, then when, then where, then who's exempt.
What if there's no time plate at all?
Then the rule applies at all times. Time plates limit a restriction; their absence means it never switches off.
Do the arrows point at the road or along it?
Along the kerb. An arrow shows which direction the restriction runs from the pole - two opposite arrows split the street into two differently-ruled stretches.
