The 44-year-old woman and her 22-year-old daughter, who only had a provisional licence, were both twice the limit when the car they were in hit a parked vehicle on Beach Esplanade in Aberdeen on Sunday evening.
The pair were among 115 people caught driving while over the limit in the first week of a police crackdown on drink drivers during the festive period.
Seven offenders were also caught driving under the influence of drugs as part of the Association of Chief Police Officers in Scotland (ACPOS) Festive Drink Drug Drive campaign.
Deputy Chief Constable Tom Ewing, who leads on road policing for ACPOS, said: "Already during this campaign more than 120 people have ignored the warnings and driven a vehicle while under the influence of alcohol or drugs. This is not acceptable and as a society we must work together to end the scourge of drink and drug driving.
"I would once again urge people who suspect anyone of driving while under the influence to contact the police via their local office, by dialling 999 or anonymously through Crime-stoppers on 0800 555111."
