A nurse drove for 20 miles the wrong way along a dual carriageway as she fled from a violent assault in Lynn.
Dorota Wysoczanska, 36, was trying to go home when she took to the roads early on Boxing Day, Ipswich Crown Court heard on Thursday.
Stephen Dyble, mitigating, told the court Wysoczanska had been assaulted by her partner at an address in Lynn, where they were spending Christmas with his friends.
When he fell asleep, Wysoczanska fled and drove along unfamiliar roads until she reached Newmarket.
But Lori Tucker, prosecuting, said Wysoczanska, who was following satnav instructions became muddled, and missed the correct slip road leading onto the A14 and took the one leading from the westbound carriageway.
Police, alerted by worried motorists, made repeated attempts to stop Wysoczanska before her car was finally brought to a halt by a rolling roadblock near Stowmarket.
Wysoczanska, of Kingsworth, Kent, who pleaded guilty to dangerous driving and drink-driving, was found to have more than twice the legal level of alcohol for driving in her blood.
Mr Dyble said that, once Wysoczanska was on the A14 she realised she was travelling the wrong way and tried to warn oncoming drivers by flashing her lights.
He said she had not noticed laybys in which she could have stopped and felt it was too dangerous to stop and turn around in the road. She had been panicking and hoping to find a roundabout.
Sentencing her to two months imprisonment, suspended for two years, Recorder Jonathan Seely said that while he accepted she had been in a state of distress, her decision to drive away had been the wrong one.
He said: “You may have had a genuine need to get away from your abuser but getting into a car having consumed that amount of alcohol was not an option open to you.”
Wysoczanska was banned from driving for 40 months and ordered to pay £120 prosecution costs.
