Two northbound lanes of MacArthur Boulevard in Newport Beach were closed briefly following a traffic collision Wednesday afternoon.

A gardening truck and a Mini Cooper collided just before 4 p.m. north of San Joaquin Hills Road, Newport Beach Police Department spokeswoman Jennifer Manzella said.

The Mini Cooper driver suffered non-critical injuries and was transported to a trauma center for treatment, Manzella said.

The gardening truck's two occupants were not hurt.

The cause of the accident remains under investigation.
