Three people were seriously injured very early Sunday morning in a two-vehicle crash on state Route 52 in Tierrasanta.

The impact happened about 1 a.m. Sunday when two cars traveling west on the highway collided just before the Santo Road exit, according to San Diego Fire-Rescue.

The crash blocked the left lanes of the highway, causing a partial shut-down for about an hour.

There were no details about what caused the crash to occur.

Drivers of both vehicles were trapped in the cars, as was a passenger in one car. All three people were taken to hospitals as trauma patients, according the department’s Instagram post.
