Not Guilty of Not Being in Proper Control of a Vehicle

Not Guilty of Not Being in Proper Control of a Vehicle

The Court did not accept the prosecution’s case that the driver was not in proper control of her vehicle.  She was initially accused of being on her mobile phone while driving by a police officer on foot.

At all times our client denied using or even holding her phone. She was issued with a ticket and chose to fight her case in court. By the time the court papers arrived, the charge had been amended to one of not being in proper control of a vehicle. For this offence, the prosecution doesn’t have to prove that the driver lost control, only that they were not in a position to have control.  For example, if you were driving perfectly normally while reading a newspaper, few people would argue that you were not in proper control.

The police officer came to court and maintained he was certain he had seen our client on her phone. He refused to accept that he could have been mistaken. Yet with our careful cross-examination, his version of events fell apart. It became clear to the court that the officer could not be sure what he had seen. There was no evidence of bad driving and as it is not an offence to have an item in your hand while driving, the court concluded that the police had not proved its case.

Our client was acquitted and walked out of court without points or a fine.

The Court of Appeal (Criminal Division) has finally provided some much needed clarification on the law regarding driving whilst using mobile phones and handheld device.

The Court explored the definition of ‘performing an interactive communication function’ which is required in order to secure a conviction.


The law is contained in Section 41D of the Road Traffic Act 1988 and Regulation 110 of the Road Vehicles Construction and Use Regulations 1986The Road Safety Act 2006 which came into force on 27 February 2007 created a specific offence in relation to the use of mobile phones and handheld devices.

At that time, mobile phones could perform only a handful of the functions now possible. As such, the legislation was drafted to include the following interactive communication functions:

  • sending or receiving oral or written messages;
  • sending or receiving faxes;
  • sending or receiving still or moving images; and
  • providing access to the Internet.

For example, there was no reference to using a mobile phone to play music, take pictures, or make recordings. This then left the courts to interpret the legislation on their own – with very inconsistent results.

Many magistrates’ courts concluded that the purpose of the legislation was to prevent the phone being used for any purpose while driving. This meant that little regard was had to the function actually being performed by phone whilst it was held by the driver.

It also made it very difficult for legal professionals to advise clients on the prospects of success if they wanted to put forward a defence of not using a phone for an interactive communication function.


The case of DPP v Barreto 2019, makes it clear that ‘interactive communication function ‘requires the transmission of data between the phone and another person or device. Therefore, taking a photograph or video on your mobile phone while driving does not fall within the ambit of this legislation. Of course, if you send a photograph then you will be transmitting data.

The prosecution must prove that the device was being used for an interactive communication function in order to secure a guilty verdict. In practice, this will be very difficult to do if the driver alleges that they were using the phone for another purpose. It is virtually unheard of for a police officer to inspect the mobile phone of a driver who has been stopped for this offence, even when the driver has offered to show the officer the phone. The police have simply relied on having seen the driver with the phone in their hand while pressing the buttons. It appears that this may no longer be enough for a conviction.


This does not mean that drivers are free to use their phones while driving for non-interactive communication functions, because there is the risk of prosecution for a different offence. This will depend on the circumstances but alternative offences of driving whilst not being in proper control of the vehicle, careless driving and dangerous driving will be considered.
