What does Highway Code Rule 153 say?

Rule 153 (General advice (rules 144 to 158)) Traffic-calming measures. It is advisory guidance rather than law, but you are still expected to follow it and an examiner can mark a fault if you do not.

Is Rule 153 the law or just guidance?

Rule 153 is advisory, it does not use “MUST” or “MUST NOT”, so it is not directly enforceable as a standalone offence. You are still expected to follow it, and ignoring it can contribute to a careless- or dangerous-driving charge and to faults on your test.

How is Rule 153 tested on the driving test?

These foundational rules, mirrors, signals, speed, stopping distances and lighting, are assessed across the whole drive. Strong habits here keep the rest of your test calm and fault-free.

What are the common mistakes related to Rule 153?

The faults examiners most often record around this part of the Code are: skipping or rushing mirror checks before a manoeuvre; carrying an unsuitable speed for the road and conditions; reacting late because hazards were spotted too close. Rehearsing the safe habit during lessons is the most reliable way to avoid them.

What the rule says

Advisory

Rule 153 (General advice (rules 144 to 158)) Traffic-calming measures. On some roads there are features such as road humps, chicanes and narrowings which are intended to slow you down. When you approach these features reduce your speed. Allow cyclists and motorcyclists room to pass through them. Maintain a reduced speed along the whole of the stretch of road within the calming measures. Give way to oncoming road users if directed to do so by signs. You should not overtake other moving road users while in these areas. Rule 153: Chicanes may be used to slow traffic down Country roads

In plain English

Stripped of the formal wording, Rule 153 comes down to one idea: rule 153 (General advice (rules 144 to 158)) Traffic-calming measures. It is advice rather than law, but examiners and the courts still treat it as the expected standard of safe driving.

It belongs to the general rules, techniques and advice for all drivers and riders part of the Code, the habits a confident, considerate driver builds until they are automatic. The aim is not to memorise the sentence word for word, but to understand the hazard it protects you from, so you apply it without having to think when it counts.

If you are learning, treat this rule as one piece of a connected set rather than an isolated fact. The related rules below sit in the same section and reinforce each other, reading them together is how the general rules, techniques and advice for all drivers and riders part of the Code starts to feel like common sense rather than a list to revise.

Because this is advisory rather than legal, no one will fine you for the rule alone, but ignoring it can still count against you in a careless-driving case, and it will cost you faults on the test. Either way, the safe move is to build the habit early, while a driving instructor can correct it, rather than relearning it under test pressure. That is exactly what the practice routes and coaching in the DriveRoutes app are designed to help with, turning the rules below into the way you naturally drive.

Why rule 153 matters on the road

These are the foundations every other skill builds on. Solid mirror work, sensible speed and good lighting habits quietly prevent the situations the rest of the Code has to deal with.

Common faults examiners record

In the general rules, techniques and advice for all drivers and riders part of the Code, the faults most often written on the marking sheet tend to be the same handful. Knowing them in advance is the quickest way to drive them out of your own habits:

Skipping or rushing mirror checks before a manoeuvre.
Carrying an unsuitable speed for the road and conditions.
Reacting late because hazards were spotted too close.

On the day

On the day, applying Rule 153 is about doing the safe, deliberate thing slightly earlier than feels necessary: read the situation in good time, observe fully, and act smoothly. The examiner is looking for planned driving, not perfection, and good habits formed in lessons carry you through.

Quick checklist

Read the situation early and plan your response.
Observe fully before you commit to anything.
Keep your speed suitable for the road and conditions.
