Another car ploughed into the parked vehicles in Emlyn Street in Talywain near Pontypool on Sunday.
A 45-year-old woman has been charged with aggravated taking of a vehicle, driving without a licence and insurance, theft and possession of a class C drug.
She has also been bailed on suspicion of driving while unfit through drugs.
Gwent Police have talked to some witnesses but have appealed for more people who saw the incident at 15:50 BST to contact them on 101.
Motorists are counting the cost after a trail of car damage was left on a street in Torfaen.
