Salih Khater was charged with two counts of attempted murder following the incident last week.
He allegedly steered a silver Ford Fiesta towards members of the public and police officers before crashing into a security barrier outside the Houses of Parliament.
The 29-year-old – a Sudanese-born British citizen from Birmingham – appeared at Westminster Magistrates’ Court to answer the charges, which state he tried to kill members of the public at the junction of Parliament Square and Abingdon Street, and then police officers in the latter road.
Police said prosecutors would be treating the case as terrorism due to the method of the alleged attack, the targets, and the high-profile location, but Khater has not been charged with any terror-related offences.
Three people were injured during the incident, which took place at 7.37am on Tuesday.
Khater wore white trousers and a grey T-shirt as he stood in the dock and spoke only to confirm his name, date of birth, address and nationality.
His lawyer, Johanna Quinn, made no bail application and Khater was remanded in custody to appear at the Old Bailey on 31 August.
