Regulatory signs
Circular signs that give orders. Red rings prohibit; blue circles compel. These are the regulatory signs you need to recognise for the DVSA theory test and for safe driving afterwards.
Every regulatory sign in this category
Stop sign
The only sign in the UK with eight sides, and the only one where slowing down isn't good enough.
Give way sign
An inverted triangle that asks for judgement, not a guaranteed stop, and that's exactly why it trips learners up.
No entry sign
A solid red circle with a white bar, and one of the few signs where breaking the rule can quickly become dangerous, not just illegal.
No waiting sign
A red X on a blue circle that stops learners more in the DVSA test than any parking-related question deserves to.
