Max Verstappen and Liam Lawson collided in the final sector of the Autódromo Hermanos Rodríguez, leaving debris strewn across the circuit and triggering a red flag.
Heading into the final complex of corners, Lawson, on a timed lap, encountered traffic by way of an Alpine ahead.
As the New Zealander approached Turn 12, Verstappen, who also appeared to be on a push lap, lunged down the inside of his former team-mate, instigating a few corners of wheel-to-wheel action between the sister cars.
The Red Bull eventually forced its way past the Racing Bulls, with bodywork left on the racing line and unnecessary damage to both machines.
The needless incident will no doubt irritate senior figures at the joint energy drinks-backed team.
After a delay of a few minutes, the session resumed.
