When driving, is a tram driver allowed to use a mobile phone if it does not require holding the phone in his hand?

In accordance with the Road Traffic Act, the prohibition applies to using a telephone in a manner that requires holding the handset or microphone in the hand, and this applies to the drivers of all vehicles, including trams. Consequently, if operating the telephone does not require the use of the tram driver's hands, for example by using a hands-free system, it is legally permitted.
