Safety Signs Questions
CITB safety signs questions test whether you know what a sign's shape and colour tell you, and the right answer usually reads the colour first.
Most of them describe a sign in words, such as a blue circle or a green square with a white picture, and ask what it means or which group it belongs to. Our questions are built on the Health and Safety (Safety Signs and Signals) Regulations 1996 and HSE's guidance on them, known as L64. A common slip is forgetting that blue marks something you must do, such as wearing PPE. Start with the 10 free questions below, each with a worked explanation, then take the timed quiz. Practise safety signs before your CITB Operatives Test or Specialist test, and sit a full Operatives mock test when you feel ready.

How do CITB safety signs questions usually ask it?
Safety signs questions usually show or describe a sign, then ask what it means, which group it belongs to or what you should do next.
| Question pattern | What it looks like, in our words | What the right answer usually does |
|---|---|---|
| Shape and colour | You are asked which shape and colours a group of signs uses, such as warning or mandatory signs | Matches the shape to the group: round for prohibition and mandatory signs, a yellow triangle for warning, a square or rectangle for escape, first aid and fire-fighting equipment |
| A sign in words | A sign is described, such as a green square with a stretcher on it, and you pick its meaning | Reads the colour first, then uses the picture to confirm the answer |
| Signals, not boards | A question about hand signals, alarms or spoken messages used to guide a job | Counts them as safety signs and picks the agreed, coded signal over a made-up one |
Which law and guidance are safety signs questions based on?
Our safety signs questions are built mainly on the Health and Safety (Safety Signs and Signals) Regulations 1996, with HSE's L64 guidance for how signs are used in practice.
| Law or guidance | What the questions take from it |
|---|---|
| Health and Safety (Safety Signs and Signals) Regulations 1996, Schedule 1 | The colours table, the shape and colour of each group of signs, and the rules for hand signals, acoustic signals and spoken messages |
| Health and Safety (Safety Signs and Signals) Regulations 1996, regulation 2 | What counts as a safety sign: a signboard, a safety colour, an illuminated sign, an acoustic signal, a verbal communication or a hand signal |
| Health and Safety (Safety Signs and Signals) Regulations 1996, regulation 4 | Signs are needed only where other ways of protecting people cannot avoid or reduce a risk enough, so a sign never replaces a guard rail |
| HSE L64, Safety signs and signals: Guidance on Regulations (third edition, 2015) | Where fire exit signs go, how the words under a sign are put, and why new or young workers may not know the less common signs |
Fire exit signs and the red signs for fire-fighting equipment tie this topic to fire drills and extinguishers, which Fire Safety Questions covers.
Safety signs sample questions with worked explanations
Here are 10 safety signs practice questions, each with the answer and a worked explanation.
Sample question 1 · Safety Signs & Signals
What shape and colours does a mandatory signboard use?
- Triangular, with a black pictogram on yellow, telling you to take care
- Rectangular, with a white pictogram on green, showing a safe condition
- Round, with a black pictogram on white and a red bar across the diagonal
- Round, with a white pictogram on a blue background covering half the signCorrect answer
Why D: Mandatory signs are round with a white pictogram on blue, the blue covering at least 50%. Blue means a specific behaviour or action, such as wear PPE.
Sample question 2 · Safety Signs & Signals
Under the safety colours table, what does blue mean?
- A warning of a hazard that you should examine before you go any further
- A prohibition, marking behaviour that is dangerous and is not allowed
- A safe condition, marking exits, escape routes and emergency equipment
- A specific behaviour or action, for example that PPE must be worn thereCorrect answer
Why D: Blue is the mandatory colour. The table gives its meaning as specific behaviour or action, with wear personal protective equipment as the example.
Sample question 3 · Safety Signs & Signals
When are safety signs required under regulation 4?
- As standard on construction sites, before a risk assessment is done
- Where risk remains after collective protection and other measures are usedCorrect answer
- Only where the client has specifically asked for signs in the contract
- Only in areas of a site where members of the public may be able to enter
Why B: Regulation 4 makes signs a residual measure. They are required where the employer, having adopted collective protection and other methods, still cannot avoid or adequately reduce the risk.
Sample question 4 · Safety Signs & Signals
When must hand signals or verbal communication be used?
- Whenever radios are unavailable anywhere on the construction site
- Only during the hours of darkness when signboards cannot be read
- To guide people who are carrying out hazardous or dangerous manoeuvresCorrect answer
- Only where a permanent signboard has been damaged and not replaced
Why C: Part I says hand signals and/or verbal communication must be used where the occasion requires, to guide persons carrying out hazardous or dangerous manoeuvres.
Sample question 5 · Safety Signs & Signals
Where natural light is poor, what does the guidance in Part II suggest for signboards?
- That the signs are made larger to compensate for the lack of daylight
- That the signs are moved to a position closer to the site entrance
- That the number of signs in the area is increased to improve the odds
- That phosphorescent colours, reflective materials or lighting are usedCorrect answer
Why D: Part II says phosphorescent colours, reflective materials or artificial lighting should be used where the level of natural light is poor.
Sample question 6 · Safety Signs & Signals
Which of these is a mandatory sign in the Schedule?
- Overhead load, warning you that loads are being lifted above the area
- Eye protection must be worn, shown as a white symbol on a blue discCorrect answer
- Fire hose, shown as a white pictogram on a square red background
- Drop, warning that there is a change of level immediately ahead of you
Why B: The mandatory list includes eye, head, ear, respiratory, foot, hand, body and face protection, safety harness, pedestrians must use this route, and a general mandatory sign.
Sample question 7 · Safety Signs & Signals
What are permanent signboards required for?
- Only for prohibitions, since those are the only signs with real legal force
- Prohibitions, warnings, mandatory requirements, escape routes, first aidCorrect answer
- Only for fire-fighting equipment and the routes leading out of the site
- Only for hazards that will remain in place for more than thirty days
Why B: Part I lists permanent signboards for prohibitions, warnings and mandatory requirements, and for the location and identification of emergency escape routes and first-aid facilities.
Sample question 8 · Safety Signs & Signals
Can a safety colour be used instead of a signboard?
- No, a signboard is always required and a colour can only supplement it
- No, because safety colours carry no defined meaning in the Regulations
- Yes, any of the listed options may be used if they are equally effectiveCorrect answer
- Yes, but only for marking traffic routes and for nothing else on site
Why C: Part I allows interchanging: any one of the listed options may be used if equally effective, for example a safety colour or a signboard to mark places where there is an obstacle or a drop.
Sample question 9 · Safety Signs & Signals
A green sign showing a stretcher indicates what?
- A prohibition on moving any casualty until first aid has arrived
- A warning that there is a risk of injury in the area immediately ahead
- A first-aid facility, since green marks safe conditions and first aidCorrect answer
- A mandatory instruction to report injuries to the site office
Why C: The emergency escape and first-aid list includes first-aid post, stretcher, safety shower, eyewash and emergency telephone, all white on green.
Sample question 10 · Safety Signs & Signals
'Do not extinguish with water' is which type of sign?
- A warning sign, because it flags a hazard associated with the fire
- A prohibition sign, one of those specifically listed in the ScheduleCorrect answer
- A fire-fighting sign, because it concerns how the fire is to be put out
- A mandatory sign, because it directs how the fire must be tackled
Why B: It appears in the prohibition list in Part II paragraph 3.1, alongside no smoking and no access for unauthorised persons.
Which safety signs answers catch people out?
Most wrong answers come from mixing up blue, green and red, or from forgetting that alarms and hand signals count as signs too.
Blue means you must do something. A round blue sign gives an instruction, and the colours table in the Regulations gives "wear personal protective equipment" as its example. If you guess, you may pick warning or safe condition instead, but warning signs are yellow and safe condition signs are green.
Green, not red, marks escape and first aid. A green square with a white picture shows an exit, an escape route or a first-aid point, such as a stretcher. A red square shows fire-fighting equipment instead, so a red sign with a ladder points to a fire ladder, not to help for a casualty.
A sign does not have to be a board. The Regulations count a safety colour, an illuminated sign, an acoustic signal, a spoken message and a hand signal as safety signs. That is why a fire alarm counts as a fire safety sign, while a written method statement is not a sign at all.
Where do safety signs sit in the CITB test?
Safety signs are part of the core knowledge you practise for the CITB Operatives test. The Specialist tests include the core questions too, so the same knowledge counts there.
Safety signs FAQs
What do safety sign colours mean?
Red means prohibition, a danger alarm or fire-fighting equipment, yellow or amber means a warning, blue means something you must do, such as wear PPE, and green means an emergency escape or first aid. This is the colours table in Schedule 1 to the Safety Signs and Signals Regulations.
Are these the real CITB test questions?
No. These are practice questions written for this site, each tied to the law or HSE guidance it tests; CITB does not publish its test questions.
