Police issued 23 traffic infringements in a two-hour blitz in the Hobart CBD this morning.

One driver was fined after failing to stop for a red light, 21 people were caught using their mobile phones while driving and one person was issued an infringement for inattentive driving.

The blitz involved officers in uniform and plain clothes, either on foot or in traffic in a range of vehicles.
