An American drink-driver argued that she should not be arrested because she is a "very clean, thoroughbred, white girl", police documents state.

South Carolina woman Lauren Elizabeth Cutshaw, 32, was allegedly caught driving through a stop sign at twice the speed limit while under the influence early Saturday morning.

When pulled over police, she gave a lengthy explanation as to why she should not be arrested.

According to local paper the Island Packet , Cutshaw said she had perfect grades in high school, she was a cheerleader, she was in a sorority, her partner is a policeman, she graduated from a "high accredited university" and it was her birthday.

She also added: "I'm a white, clean girl."

"You're a cop. You should know what that means."

She was arrested nevertheless, with the officer listing her excuses because they "further demonstrate the suspect's level of intoxication".

The New York Post described Cutshaw as "the picture of entitlement".

Cutshaw told police she had only had two glasses of wine, but had a 0.18 percent blood-alcohol level.
