A driver of a 30 tonne lorry was making a phonecall while motoring with poor tyres.
The driver was stopped by members of the Buncrana Roads Policing Unit who hit him with a Fixed Charge Penalty notice on Wednesday.
A caution was given in relation to the poor condition of the inner tyres each side of the rear axle.
A Garda spokesperson said “Please never hold/use your mobile phone while driving. It is so important that you are not distracted in any way whilst behind the wheel of any type of vehicle.
“Please check your tyres regularly and even more regularly when the tread depth reaches 3mm. The legal minimum tread depth is 1.6mm.
“The more worn your tyres become, the less grip they will have on the road surface.”
