The topographical test explained — map reading for taxi drivers

The topographical skills test checks whether a taxi or private hire driver can read a map and plan a sensible route without relying on satnav. It is a practical, paper-and-pencil style assessment of your ability to find places, follow directions and work out the best way from A to B. This guide explains exactly what the test assesses, which authorities require it and how to prepare so you pass with confidence.

What is a topographical test for taxi drivers?

"Topographical" simply means relating to the layout of an area — its streets, landmarks and geography. The test gives you a street atlas (such as an A-Z) or an Ordnance Survey style map and asks you to locate destinations, identify the page and grid reference, and plan routes. The purpose is to prove you can navigate professionally and keep passengers moving even when technology fails. It is a separate assessment from the SERU test, which covers rules and safety rather than navigation.

What the topographical test assesses

Although the exact paper varies by licensing authority, most topographical tests check the same core skills:

• Reading a street atlas or OS map. Using the index to find a place, then locating it on the correct page.
• Grid references. Reading the grid squares to pinpoint a location. On Ordnance Survey maps the convention is to read the eastings before the northings — you go "along the corridor, then up the stairs."
• Map scale and symbols. Understanding common scales — for example OS Landranger maps are 1:50,000 and Explorer maps 1:25,000 — and recognising standard symbols for hospitals, stations, schools and landmarks.
• Compass directions. Working out whether a journey runs north, south, east or west, and following directional instructions across a map.
• Identifying the quickest route. Choosing the most efficient path between two points, taking one-way streets and main roads into account.
• Calculating distance and time. Using the scale to estimate how far a route is and roughly how long it will take.

You will typically be asked to note the page number and grid reference of each answer, so accuracy and neatness matter as much as speed.

Which councils require a topographical test?

Transport for London requires a topographical skills assessment for London private hire drivers, and you must reach the published pass standard to be successful. Outside London, requirements vary by licensing authority. Some councils require a topographical or "knowledge" test for hackney carriage (taxi) drivers in particular — Glasgow City Council, for example, requires its Topographical Test of Knowledge for licensed taxi drivers. Others test private hire applicants too, while some have no topographical requirement at all.

Because the rules differ so much from one area to the next, the only reliable way to know what you must sit is to check the licensing pages for your council. Our overview of how to become a private hire driver explains where this test fits into the wider application.

How to prepare for the topographical test

The good news is that these are learnable, mechanical skills. A little structured practice goes a long way:

1. Get comfortable with a real map. Buy or borrow the street atlas your area uses and practise looking up places via the index, then finding the page and grid square.
2. Master grid references. Drill the eastings-before-northings rule until it is automatic, and practise reading references to four and six figures.
3. Learn the symbols and scale. Memorise the common map symbols and how to convert map distance into real distance using the scale.
4. Practise route planning against the clock. Pick two points, plan the quickest sensible route, then estimate distance and journey time. Speed comes with repetition.
5. Work through realistic questions. Our free topographical practice covers grid references, compass directions and route planning in the same style as the real assessment.

If you are also licensing in London, line up your revision so you can tackle SERU and topographical together — see our SERU test guide. And since all professional drivers benefit from strong road knowledge, it is worth sharpening up with Highway Code practice too. When you are ready, run through a full set of practice tests to confirm you are passing comfortably before you book.
