To the Public Danger is a 1948 British drama short film directed by Terence Fisher and produced by John Croydon.
The screenplay, written by T.J. Morrison and Arthur Reid, was based on a 1939 radio play by Patrick Hamilton, who had been encouraged to write the story as part of a government road safety campaign.
While having a quiet drink together in a road house, a young working-class couple Fred and Nancy fall into the company of two raffish motorists including the self-confident Captain Cole.
Nancy takes Cole's side and begins taunting Fred, who eventually manages to escape and raise the alarm.
A police investigation reveals that nobody had been injured in the collision with the bike, which had belonged to a poacher who didn't report the accident.
