On 4 October 1948, while Bhumibol was driving a Fiat Topolino on the Geneva-Lausanne road, he collided with the rear of a braking truck 10 km outside of Lausanne. He hurt his back and incurred cuts on his face that cost him the sight of his right eye.[20][21] While he was hospitalised in Lausanne, Sirikit visited him frequently. She met his mother, who asked her to continue her studies nearby so that Bhumibol could get to know her better. Bhumibol selected for her a boarding school in Lausanne, Riante Rive. A quiet engagement in Lausanne followed on 19 July 1949, and the couple were married on 28 April 1950, just a week before his coronation.
