Can Spittleborough Roundabout at M4 Junction 16 Be on a Swindon Driving Test Route?

Yes. Spittleborough Roundabout at M4 Junction 16 can be used during a driving test from Swindon.

It's the large multi-lane roundabout to the west of Swindon where the A3102 meets Junction 16 of the M4.

Being at a motorway junction doesn't mean you'll be expected to join the motorway. The roundabout itself is part of the normal road network and can be used without entering the M4.

What is Spittleborough Roundabout like?

Spittleborough is a large, multi-lane roundabout connecting West Swindon and Royal Wootton Bassett with the M4.

Despite its size, it's relatively straightforward to read. As of August 2026, it is well signed and the lane markings are clear.

If you encounter it during your driving test, use the signs and road markings to work out where you need to go and which lane you need.

You may also be following a sat nav or have been asked to follow signs towards a destination, depending on how the independent driving part of your test is being conducted.

There's no need to memorise the roundabout or learn which lane to use for every possible destination.

What should you concentrate on at Spittleborough Roundabout?

Treat it in the same way you would any other large, multi-lane roundabout.

Plan early enough to read the signs and road markings, choose the appropriate lane and maintain your position as you travel around it.

Keep observing the traffic around you as well. Being in the correct lane doesn't guarantee that everyone else will be.

If you realise you're in the wrong lane, deal with the situation safely rather than making a sudden change just to follow the original direction.

Can you go on the motorway during your driving test?

No. The practical car driving test does not include motorway driving.

You can therefore encounter Spittleborough Roundabout at M4 Junction 16 during a Swindon driving test without being asked to join the M4.

Learner drivers are allowed to drive on motorways during lessons, but only when accompanied by an approved driving instructor in a dual-control car.

Should you practise Spittleborough Roundabout before your Swindon driving test?

You can, but there's no need to repeatedly practise it because you think it might appear on your test.

It's a useful place to gain experience of reading signs and road markings, choosing lanes and dealing with a larger multi-lane roundabout.

Then use those same skills somewhere else.

If you encounter Spittleborough during your test, you should be able to deal with it because you can read and respond to the road in front of you, not because you've memorised what to do there.
