Chloe Hawes failed to give way at a junction and drove her Mini into the path of a Peugeot 207, causing a collision.
Peterborough Magistrates’ Court heard that the junction of Chariot Way and Kings Hedges Road in Cambridge is controlled by traffic lights.
Prosecutor Sharon Chattey said the circumstances of the collision “would probably indicate that there was some high speed”.
The court was told that Hawes, of Rustat Close in the city, already had six penalty points on her licence from two offences of driving otherwise than in accordance with a licence. The most recent was in January this year before she passed her test.
Hawes said: “I definitely wasn’t going fast, about five to ten miles per hour.
“The Peugeot hit the passenger side and it’s literally flipped me over.”
Solicitor Claire Thorneley urged magistrates to impose sufficient penalty points so that Hawes would be able to keep her job as a delivery driver for a sushi restaurant.
“She took a wrong turn literally and figuratively,” added Miss Thorneley.
Hawes, who pleaded guilty to driving without due care and attention on May 20, was given five penalty points, fined £80 and ordered to pay £110 costs and £34 victim surcharge.
