Spalding magistrates banned a Thurlby woman from driving for six months.
Lesley Inman (44), of Lawrance Way, drove in Meadowgate Lane, Bourne, without insurance on August 29 last year.
The court heard on Thursday that Inman already had six points on her licence and the insurance offence took her to 12, triggering the ban.
She was also fined £600 and must pay £85 costs with a £13 victim surcharge.
