You’re looking for somewhere to park at night. When may you park on the right-hand side of the road?
Rule 239 of the UK highway code states:
Do not park facing against the traffic flow
And rule 249 states:
You MUST NOT park on a road at night facing against the direction of the traffic flow unless in a recognised parking space.
If you are on a one way street then you aren’t facing against the traffic flow so the above statements don’t apply.
Normally you park on the left hand side although there may be some occasions where you need to park on the right. If so, here’s a handy guide to pulling up on the right hand side.
