What You Need to Know About the PCO Knowledge Test

If you’re planning to become a PCO driver in London, one of the key steps is getting your PCO licence—and that means passing the PCO Knowledge Test.
Introduced by Transport for London (TfL), this test checks your understanding of London’s key roads, landmarks, and traffic rules. It ensures you’re prepared to navigate the city safely, efficiently, and professionally.
Here’s a breakdown of what to expect—and how to prepare.
Test Overview: What It Covers
The PCO Knowledge Test includes five main sections:
- Map Reading & Route Planning
- Basic Maths
- Private Hire Policy & Conditions
- Road Safety & Hazard Awareness
- Equality & Customer Service









1. Map Reading & Route Planning
You’ll be asked to select the most practical routes using diagrams and maps. Expect questions about:
- Navigating key roads and avoiding restricted zones
- Using landmarks to guide journeys
- Choosing the fastest or most efficient routes
You don’t need to memorise every street, but a solid understanding of London’s layout is essential.
2. Basic Maths
This section ensures you can handle day-to-day fare-related calculations, such as:
- Giving the correct change
- Working out percentages (e.g. 15% of £40)
It’s straightforward, but quick mental maths practice can really help.
3. Private Hire Policy & Conditions
This part covers the rules you must follow as a private hire driver:
- Only accepting pre-booked passengers (no street hails)
- Displaying your PCO badge at all times
- Understanding your legal responsibilities
Tip: TfL’s Private Hire Driver Handbook is essential reading.

Much of this overlaps with The Highway Code, so if you’ve passed your UK driving test, you’ll already have a strong foundation.
5. Equality & Customer Service
This section tests how well you serve and respect all passengers, including:
- Supporting passengers with disabilities
- Dealing calmly with complaints or disputes
- Treating everyone equally—regardless of background, gender, or ethnicity
Being respectful and professional at all times is key.
