A passenger in a car has filmed a driver staring at something in her car rather than the road while cruising on the M4.
The footage shows her, despite going at a fast speed, looking at what appears to be a mobile phone in her hand.
The incident happened at around midday on Thursday on the eastbound carriageway near J32 for Chepstow.
A woman driving a red Mercedes is seen with one hand on the steering wheel and but looking at something that looks like a mobile phone in her other hand, reports Wales Online.
Despite driving in the middle lane of the motorway, her focus seems to be on the object in her hand rather than on the road. She also drifts across the lane.
The footage was filmed by Chrisopher Haul, who was a passenger in a car travelling behind the Mercedes.
"I was filming her for a while and when we passed her she had what appeared to be her phone in her hand the whole time," Christopher said.
According to the government website, it is illegal to hold a phone or sat nav while driving or riding a motorcycle.
You must stay in full control of your vehicle at all times and the police can stop you if they think you’re not in control because you’re distracted and you can be prosecuted.
You can get six penalty points and a £200 fine if you use a hand-held phone when driving - or if you've only been driving for two years, could potentially lose your licence.
You can also get three penalty points if you don’t have a full view of the road and traffic ahead or proper control of the vehicle.
In some cases you can even be taken to court where you can be banned from driving or riding and get a maximum fine of £1,000.
A spokesman for road safety charity Brake said: “Driving is a highly complex task, where even a momentary distraction can be fatal, particularly on high-speed roads like motorways.
"Our roads are busy places, and we would urge drivers to keep their eyes on the road, hands on the wheel and place any distractions, such as mobile phones, out of reach.”
Anyone with information regarding this incident should contact Gwent Police on 101.
