What this dot point is asking

CCEA wants you to know what the Highway Code is, what legal status it carries, the crucial difference between its MUST/MUST NOT rules and its advisory rules, and the full range of road users it is written for. This is foundation material for Unit 1: almost every other topic in the course refers back to the Code, and "according to the Highway Code..." is one of the most common openings in the written exam.

The answer

What the Highway Code is

The Highway Code is the official set of information, advice, guides and mandatory rules for everyone who uses the road in the United Kingdom, including Northern Ireland. In Northern Ireland it is published by the Department for Infrastructure / DOE NI; the version of the Code reproduced in CCEA exam papers carries the line "Contains public sector information licensed under the Open Government Licence".

Its purpose is to promote road safety by making sure all road users understand the rules and behave predictably. The Code applies to everyone, not just drivers, and a sound knowledge of it is essential for passing both the theory and the practical parts of learning to drive or ride.

MUST / MUST NOT versus advisory rules

This distinction is examined again and again, so learn it precisely.

Even so, an advisory rule still matters in law: if you are involved in a collision, the fact that you ignored Highway Code advice can be used as evidence in court to help establish liability, even though breaking the advice was not the offence itself.

Categories of road user

The Code is deliberately written for a wide range of users, and it places extra responsibility on those who can do the most harm to protect those most at risk (the hierarchy of road users). The main categories are:

  • Pedestrians (including children, older people and disabled people).
  • Cyclists (pedal cyclists).
  • Motorcyclists and moped riders.
  • Drivers of cars, vans, buses, lorries and other motor vehicles.
  • Horse riders and people in charge of animals.
  • Users of powered wheelchairs and mobility scooters.

The most vulnerable road users are pedestrians, cyclists, motorcyclists and horse riders, because they have least protection in a collision.

Worked example: classifying a rule

Examples in context

Example 1. A "MUST" rule. "You MUST wear a seat belt if one is fitted." The word MUST tells you this is law (the seat belt regulations), so a driver or passenger ignoring it commits an offence.

Example 2. A "should" rule. "You should leave a two-second gap from the vehicle in front." This is advice on safe following distance. A tailgating driver has not automatically committed the seat-belt-style offence, but if they hit the car in front the closeness can count against them.

Q1. What is the main purpose of the Highway Code? [1 mark]

  • Cue. To promote road safety by setting out the rules and advice for all road users.

Q2. Does the rule "You MUST stop at a red traffic light" describe law or advice? [1 mark]

  • Cue. Law - it uses MUST, so breaking it is an offence.

Q3. Name two of the most vulnerable categories of road user. [2 marks]

  • Cue. Any two of: pedestrians, cyclists, motorcyclists, horse riders.

Exam-style practice questions

Practice questions written in the style of CCEA exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.

CCEA style4 marksExplain the difference between a Highway Code rule that uses the words MUST or MUST NOT and one that uses should or do not, and give one example of each.
Show worked answer →

A rule that uses MUST or MUST NOT is a legal requirement: it is backed by a specific Act of Parliament or regulation, and breaking it is a criminal offence that can lead to a fine, penalty points, disqualification or even prison. An example is "You MUST wear a seat belt", or "You MUST NOT use a hand-held mobile phone while driving".

A rule that uses should, should not or do not is advisory: it is strong guidance on good practice but is not in itself an offence to ignore. An example is "You should leave at least a two-second gap from the vehicle in front".

Markers reward: MUST/MUST NOT is law and an offence, should/do not is advice, plus one correct example of each.

CCEA style3 marksThe Highway Code states that it is essential that all road users are aware of the Code. List three different categories of road user the Code applies to.
Show worked answer →

Any three of: pedestrians; cyclists (pedal cyclists); motorcyclists and moped riders; drivers of cars and other motor vehicles; horse riders and people in charge of animals; and users of mobility scooters or powered wheelchairs.

Markers reward three genuinely different categories. Listing "car drivers" and "lorry drivers" as two separate answers would usually only score once, because both are motor-vehicle drivers.
