Why do vehicles go clockwise?

On roads where traffic keeps left, you turn left into a roundabout and give way to traffic from your right, which goes the same way round. Where traffic keeps right, roundabouts go the other way, anticlockwise.

Why does a longer vehicle need a wider line?

Its back wheels follow a tighter circle than its front ones, and the whole body needs room to swing through. The longer the vehicle, the bigger the circle it needs, so a bus has to start its turn earlier and use more of the road.

Roundabout Test

Drive in, go round the island and take the exit you are told. The island is solid, the corners of the blocks pinch the ring, and a bigger vehicle needs a wider line to get round. Take the first, second or third exit, in a car, then a van, then a bus, and go round extra laps on the later tests. Six tests of growing difficulty.

How to play

Drive with the arrow keys or the on-screen pedals. You enter from the bottom arm. Traffic goes clockwise round the island, so turn left onto the ring and keep the island on your left.
The goal line tells you which exit to take and how many extra laps to make first. Pass the blue checkpoints around the ring, then drive out of the exit and stop wholly inside the green bay at the end of it.
The island is solid and the pinch points at the corners are narrow. Touching them damages the vehicle, and too much damage ends the test.

Tips and strategy

Slow down before you enter, then drive a smooth circle at a steady speed. Steering a little all the way round is easier than a sharp turn at the end.
A bus swings its rear end wide, so take the ring on the outside part of the lane through the pinch points and keep a little further from the island.
Count the exits as you pass the side roads, not as you reach them: the first exit is the first one on your left after you enter.
