Yes it is. It is another exemption. I remember once I had a complaint about one of my off duty officers who was using his phone in his hand whilst following a suspected drink driver on the way home from work and the driver was subsequently arrested. His father, a solicitor, phoned me as I was his supervisor, to complain that a police officer was driving whilst using a handheld phone and wanted him dealt with. I had great pleasure informing the solicitor to read up on the law, and sent him the copy of the section.
