Lorry spotting sits somewhere between trainspotting and birdwatching, and it costs about as much to start. A pen, a notebook and a route with steady traffic will do for day one. What turns the hobby from a blur of white boxes into something you can follow properly is knowing what to bring, which references to keep open on your phone, and how to behave when you pull into a truck stop that is, first and foremost, somebody's workplace.

Nothing below needs a big budget, and nothing below requires you to stand anywhere you shouldn't.

The kit that earns its place

You do not need much, but the few things you carry should be chosen for cold hands and bad light.

• Camera or phone with a decent zoom. Most sightings happen at 40 mph across a dual carriageway, so reach matters more than megapixels.
• Notebook and two pens. Paper does not run out of battery, and writing a registration by hand fixes it in your memory.
• Binoculars, something like 8x42. Useful from a bridge or a layby, less useful from a moving car.
• Power bank and cable. Apps and cameras drain a phone quickly on a long day.
• Weatherproof jacket, gloves, flask. Laybys are wind tunnels.
• A small torch. Winter afternoons go dark early and you will still be writing.
• Hi-vis vest, worn carefully. Handy in a proper truck park after dusk. Do not wear it around a working yard, where drivers may assume you are staff and ask you to move something.

Apps and fleet lists: build a small reference shelf

Most spotting apps do two jobs: they let you log a registration and they tell you what that registration is. Some add photo galleries, livery histories and a wanted list you can tick off. Try two or three free ones, keep the one whose database covers the fleets you actually see, and be ready to pay a small subscription for the fuller version. Check what happens to your records if you stop paying, and keep a paper backup either way.

For official detail, bookmark the free government vehicle enquiry and MOT history services. Enter a registration and you get make, colour, and tax and test status. They will not tell you the fleet number, but they confirm you read the plate correctly. Vehicle operator licence records, published by the traffic commissioner, are also public and can help you work out who runs a livery you do not recognise.

Fleet lists are the hobby's real currency, shared through enthusiast forums, printed fleet books and spreadsheets. Two habits keep them useful:

1. Record the fleet number and the registration. Fleets sell vehicles on, so a number that belonged to one operator last year may be running in different colours now.
2. Note the date and place. A list is only a snapshot, and you will spot changes long before any published list catches up.

What to write down

Date, time, location, operator, fleet number, registration, make and model, plus a one-line note on livery or trailer. Add anything unusual: a rare body type, a newly delivered vehicle, a livery being phased out. Those details are what make your records worth reading in five years.

Roadside etiquette: be welcome, not a nuisance

Truck stops and service areas

Park in the car park, not in a truck bay. HGV parking is in short supply and drivers plan their day around it; a car in a bay takes a space from someone who needs a legal rest. Then buy something — coffee, a sandwich, fuel. You are using their facilities and their tolerance.

Ask before photographing inside a yard or depot. From a public footpath or layby you can photograph what is visible, but a security gate is a clear signal. Never enter a site, never climb on a vehicle, never open a cab door, even for a better angle at a badge.

Drivers are usually happy to chat if you catch them on a break and open simply. "Do you mind if I take a photo of the truck?" works. Do not stand between them and their sandwich, do not ask them to move the vehicle, and do not photograph a driver's face without asking. Plates are public; people are not exhibits.

Staying safe at truck stops and laybys

Laybys on fast single carriageways are the riskiest places in the hobby. There is often no barrier between you and traffic doing 60 mph. Treat the carriageway as off limits and stay behind the kerb line.

1. Choose where you will stand before you park: behind a barrier, on a wide verge, on a bridge with a pavement, or in an official viewing spot.
2. Never walk behind or beside a truck that might move. Air brakes release with little warning and reversing vehicles have large blind spots.
3. Be visible after dark, and keep to lit areas with other people around.
4. Do not approach a parked lorry at night on your own. Note what you need and come back in daylight.
5. Take a friend, tell someone your route, and keep your phone charged.

If you are spotting with children, agree the boundary in advance — the kerb, the fence, the car — and hold to it.

Your first trip

Start somewhere you already know: a service area car park, a bridge over a busy A-road, or a truck stop with a café. Take a flask, a notebook and your phone. Sit for an hour, write down twenty registrations, and look half of them up when you get home. Build your list slowly, from what you actually see rather than what someone else has catalogued — the sightings you make yourself are the ones you remember.

Ask permission where it matters, stay out of the way, buy the coffee, and log what you see. Do that and lorry spotting stays a hobby you can keep for years without ever becoming a problem for the people who drive for a living.
