Can an impaired accused leave the headlights illuminated on his immobile vehicle to warn passing motorists of the obstruction?

40. However there can be dangers other than putting a vehicle in motion as this is only one example. Potential danger can exist where an impaired accused leaves the headlights illuminated on his immobile vehicle in order to warn passing motorists of the obstruction. The impairment of the accused can lead to some risk if the headlights are shut off either accidentally or deliberately. R v. Vansickle, [1990] OJ 3235 (OCA).
