Derek's Cadillac flipped over just after 3 AM PT Sunday as he was heading northbound on the Ventura 101 Freeway. His passenger was "Basketball Wives" star Gloria Govan. Neither Derek nor Gloria were injured.
Derek was then arrested and jailed after it was determined he'd been drinking. The car wreck could have been deadly from how badly the car had flipped ... based on video obtained by TMZ Sports.
CHP officials say Derek veered into the paved right shoulder of the 101 just east of the 405 interchange. He collided with the raised concrete curb and guardrail, which flipped his car over once. Luckily, the crash left both Derek and Gloria unscathed.
We got Derek Saturday night leaving Catch at 11:45 PM, but he crashed at 3 AM. He apparently picked up Gloria after dinner, because she wasn't at Catch. He and Gloria have been an open couple since March.
