Police caught a drink-driver after spotting him steering with one hand and using his mobile phone with the other.
Danny Fuller was seen by a police patrol driving a Renault Master van in Trinity Place, Eastbourne, while on the phone at about 2.30am on 27 December.
The 29-year-old pulled over as if to park and when a police officer opened the driver’s door, Fuller was still using his mobile.
He was breathalysed and found to also be over the drink-drive limit.
Fuller, of Linden Road, Eastbourne, pleaded guilty to drink-driving and using a mobile phone at the wheel when he appeared at Hastings Magistrates’ Court on 18 February.
He was banned from driving for 12 months, fined £320 and ordered to pay £85 costs and a £32 victim surcharge.
Chief Inspector Phil Nicholas, from Surrey and Sussex roads policing unit, said: “Both drink-driving and using a phone at the wheel are dangerous individually but combining them could have been deadly.
“Fortunately, in this case the alertness of the officer on patrol meant that we were able to catch Fuller before he hurt someone.
“Drink-driving is totally unacceptable and I would urge anyone who sees someone who they suspect is drink-driving to contact us so we can take action immediately.
“Using a mobile phone can be equally as dangerous because it dramatically affects how much you are concentrating on the road and what is around you.
“Don’t do it, don’t get in a car with someone who does it and call us if you see someone doing it.”
