Key legal question
Whether the traffic rules act applied to the manoeuvre on the forecourt and staircase.
Extracted holding
Yes. The forecourt was a public traffic area because it was open to an indeterminate circle of users, so the traffic legislation applied.
Extracted reasoning
Publicness depends on use by the general public, not ownership. The defendant used a public traffic surface before the car stopped, and a vehicle that leaves the road after a faulty manoeuvre remains subject to traffic rules.
