Tory MP Jamie Wallis has been charged with failing to stop and driving without due care and attention following a car crash in November last year, South Wales Police said.
Wallis has also been charged with failing to report the crash, careless driving and leaving a vehicle in a dangerous position.
The MP for Bridgend is due to appear before Cardiff Magistrates’ Court on Tuesday 10 May.
Wallis became the first MP to come out as transgender in March and said he hopes to begin transitioning “as quickly as possible”.
Jamie Wallis last month tweeted that he has gender dysphoria and had been raped and blackmailed.
He told Sky News’ Sophy Ridge afterwards that a part of him “died” following the rape.
He was elected to represent Bridgend at the 2019 general election, unseating Labour for the first time in three decades.
In a statement, South Wales Police said the force had been “been investigating a road traffic collision which happened in Llanblethian, Cowbridge, in the early hours of Sunday, November 28, 2021.
The statement added: "Jamie Wallis, 37, from Cowbridge has been charged with failing to stop following a road traffic collision, failure to report a road traffic collision, driving without due care and attention and leaving a vehicle in a dangerous position."
Wallis won his seat in December 2019, managing to oust Labour's Madeleine Moon who had held the constituency for 14 years.
The following month there were calls in the House of Commons from Opposition MPs for him to apologise after company records showed he had held a business interest in a so-called "sugar daddy" website called Sugar-Daddy.net which was branded "exploitative and demeaning".
In February this year, Wallis was fined £270 and received three points on his licence at Cardiff Magistrates' Court after admitting the offence of crossing a solid white line while driving a Mercedes on the A48 in August 2021.
