Lines painted on the road separate traffic into lanes.

Roads with more than one lane going in each direction are called ‘multi-lane’ roads.

Most multi-lane roads have two lanes for each direction, like the one in this picture.

2 lanes in each direction

Other multi-lane roads, such as motorways and expressways, may have three or four lanes in each direction.

You should drive in the left lane of a multi-lane road unless you want to turn right or you want to pass another vehicle.
