Driver CPC Module 4 Explained: The Practical Demonstration Test

Where Module 4 sits

The initial Driver CPC has four modules. Module 1 is the theory, split into multiple choice and hazard perception. Module 2 is the case study paper. Module 3 is the practical driving test, the one with the reversing exercise and the road drive. Module 4 is the practical demonstration test, and it is the only one that is not about driving at all. You can take it before or after Module 3, though most people do it after.

You only need Module 4 if you are driving professionally. Someone taking C1 for a horsebox or a motorhome, or D1 for voluntary community transport, does not need Driver CPC at all and can skip it entirely.

The five topics

How it is marked

Each of the five topics is scored out of 20. You must score at least 15 in every single topic and at least 80 out of 100 overall. That double threshold is the reason people fail: a candidate can be excellent on load security and safety checks, score 19 and 18, and still fail because they only managed 12 on trafficking. There is no averaging your way past a weak topic.

The most commonly failed topic is preventing trafficking in illegal immigrants, purely because candidates have not learned the vehicle security check sequence. It is twenty minutes of revision that decides the test.

What the examiner wants to see

Module 4 is a demonstration, so demonstrate. Where there is equipment to hold, hold it. Where there is a check to point at, point at it. Candidates who stand still and talk score lower than candidates who move around the vehicle and show. The examiner may ask you to explain your reasoning, and explaining why you would do something almost always earns more than describing what you would do.

• Use the equipment: straps, ratchets, chocks, high visibility clothing, warning triangle.
• Talk through calculations out loud on the loading topic; the working matters.
• Know your safe working load markings and how to spot a damaged strap.
• For trafficking, learn the order of the security check and the fact that responsibility sits with the driver and the operator.
• For emergencies, cover making the scene safe before anything else.

Load security in detail

This topic carries the most marks in practice because it has the most content. You need to understand that a load must be restrained against forward, rearward and sideways forces, that forward restraint needs the most capacity because braking generates the highest force, and that straps have a rated capacity marked on the label. You should be able to explain headboard restraint, friction, and why a load that has settled after twenty miles needs its straps rechecked.

Preparing efficiently

Module 4 does not need weeks. It needs a focused half day with someone who knows the mark scheme, at a vehicle, physically doing the five topics. That is exactly how we run it, and at £199 it is the cheapest module in the whole qualification. Trainees who try to self prepare from a booklet are the ones who come back for a retest.

After Module 4

Pass all four modules and DVSA issues your Driver Qualification Card, the DQC, which you must carry when driving professionally. It lasts five years, after which you keep it valid with 35 hours of periodic training. Ours is £55 per seven hour course, so £275 across a full five year cycle.

Do I need it if I already drive?

If you have held vocational entitlement and driven professionally continuously, you may hold acquired rights and only need periodic training rather than the initial qualification. If your entitlement lapsed or you have never driven for a living, you need the initial modules including Module 4. Ring us and read out your licence categories and DQC status, and we will tell you which applies.
