Highway works: why it matters
Roadworks put you a few steps from fast-moving traffic, with vehicles, plant and the public all close together. Being struck by a vehicle is one of the biggest risks, so layout and visibility are everything.
Temporary traffic management follows Chapter 8 of the Traffic Signs Manual. It sets out how to sign, light and guard a works area so drivers are warned in good time and a safe zone is created for the workforce.
Highway works revision notes
The points below are the core of what the CITB test wants you to know on this topic. Learn these and most questions answer themselves.
Chapter 8 layouts
Signs, cones and barriers must follow Chapter 8: advance warning signs, a tapered lead-in with correctly spaced cones, a safety zone, the works area, then an exit taper. The layout is not arbitrary.
The safety zone
A gap is kept between the traffic and the people working. Never work, stand or store materials in the safety zone, it is there to absorb a vehicle that strays off line.
High-visibility clothing
Hi-vis to EN ISO 20471 is essential, and a higher class is required on high-speed roads. Keep it clean and fastened so it reflects properly day and night.
Trained and accredited
Setting out and working in traffic management requires recognised training and accreditation, because a poor layout puts both the workforce and the public at risk.
Face the traffic
Stay alert and, where possible, keep oncoming traffic in view. Have a planned escape route in case a vehicle enters the works.
Lighting and night work
At night, works must be lit and lamps fitted to cones and signs so the layout is clearly visible to approaching drivers.
Hear a question in Polish

What is the first step you should take before starting work on a highway project?
Start the machinery
Check weather conditions
Ensure a work permit is granted
Set up traffic cones
Every wrong answer can also come with an AI explanation that points to the specific rule behind the correct answer, so you learn from each mistake instead of just memorising. Native Polish audio and AI explanations are two things you will not find on other CSCS practice sites.
Highway works practice questions
Five questions in the real CITB format: one stem, four lettered options, one correct answer. Select Reveal explanation to check your answer and read why it is right.
Q1. Why is it important to set up traffic management signs before roadworks?
- A.To increase road user speed
- B.To inform road users of upcoming conditions
- C.To make the site look professional
- D.To attract more workers
Reveal explanation
Correct answer: B. To inform road users of upcoming conditions
Traffic management signs are crucial for informing and guiding road users through or around the construction site safely.
Q2. Which piece of personal protective equipment is mandatory for all highway workers?
- A.Hard hat
- B.Safety boots
- C.High-visibility clothing
- D.Ear protection
Reveal explanation
Correct answer: C. High-visibility clothing
High-visibility clothing is vital for ensuring that workers are seen by drivers and machinery operators.
Q3. What should you do if you discover uncovered manholes on a roadwork site?
- A.Cover them immediately with whatever is available
- B.Report it to the site supervisor for proper action
- C.Place a cone nearby and work around them
- D.Ignore and continue working
Reveal explanation
Correct answer: B. Report it to the site supervisor for proper action
Uncovered manholes are a significant hazard, and the supervisor should be informed to address the issue appropriately.
Q4. Which document outlines the specific safety procedures for a highway construction site?
- A.Operating Manual
- B.Hazard Report
- C.Method Statement
- D.Risk Assessment
Reveal explanation
Correct answer: C. Method Statement
A Method Statement details the specific procedures and safety measures for carrying out a task on site.
Q5. What is the purpose of a risk assessment in highway works?
- A.To create more paperwork
- B.To identify and control potential hazards
- C.To train new workers
- D.To allocate job roles
Reveal explanation
Correct answer: B. To identify and control potential hazards
Risk assessments are critical for identifying potential hazards and implementing control measures to ensure safety.
Common mistakes
These misconceptions catch people out in the test and on site. Unlearn them before you sit the real exam.
Mistake 1: “Any hi-vis vest is fine on a fast road.”
Correct: High-speed roads need a higher class of high-visibility clothing, not a basic vest. The right class and clean, fastened garments make you visible to drivers in time to react.
Mistake 2: “Cone spacing does not really matter.”
Correct: Cone spacing and taper lengths are set by Chapter 8 for the road speed. Get them wrong and drivers are not guided safely past the works, which puts the whole crew at risk.
Mistake 3: “You can store materials in the safety zone.”
Correct: The safety zone must be kept clear. It is the buffer that protects workers from a vehicle that leaves the carriageway, so nothing and no one should be in it.
