The road starts at traffic lights on the A238 to the west of Raynes Park. It runs south and goes underneath the A298, although there is no junction with that road at this point.
After running alongside the Mole Valley Line for a few hundred yards the B282 gives way to the road coming in from the left across the level crossing. We bear right at a mini-roundabout as the route curves round towards the west. We shortly cross under the A3 at a roundabout, where there is a junction with the A298. The route continues along Burlington Road and terminates in New Malden at a roundabout junction with the A2043. The other road at the roundabout is the B283.
Originally the B282 continued along what is now the A2043 into Kingston upon Thames, where it ended on what was originally the A3 (and later became the A308). It was cut back in the 1980s.
