Amy Thakurdas, aged 68 and listed as living on Oxford Road in Kidlington, denied causing serious injuries by careless driving when she appeared at Oxford Crown Court on October 30.
The case concerns an incident in which Derek Hawkins sustained serious injuries on Banbury Road, Kidlington.
According to court documents, Thakurdas was behind the wheel of a blue Honda Jazz when the crash occurred on April 2 last year.
Following the not-guilty plea, the court scheduled her trial for January 24, 2028, with proceedings expected to last between four and five days.
Judge Hassan Khan directed the defendant to submit a detailed defence statement, warning that the failure to provide one could be considered at trial.
Thakurdas was subsequently released on unconditional bail.
