At least eleven people were killed this weekend as a result of two separate highway collisions caused by drivers traveling in the wrong direction, according to a report by Reuters.

Five people were killed during a collision in Florida, and six were killed in California.

In Tampa, F.L., a Ford Expedition SUV moving south on northbound Interstate 275 hit a Hyundai Sonata head on around 2 a.m., killing the SUV driver and all four people in the vehicle traveling in the correction direction, according to a Florida Highway Patrol news release.

The SUV became engulfed in flames, and the other vehicle was also damaged by the fire, according to the police report.

The four people were members of the Sigma Beta Rho fraternity at the University of South Florida, in Tampa.

The driver of the SUV's identity has not been confirmed due to damage to the vehicle, according to Reuters. Police are also unaware if alcohol was involved in the collision.

Six people were killed before dawn in California when a driver was traveling the wrong direction of a highway east of Los Angeles, according to the California Highway Patrol.

Three vehicles were affected by the crash on the 60 Freeway in Diamond Bar, C.A. A Chevrolet Camaro was traveling in a westbound lane of 60 east of Diamond Bar Boulevard when it hit a Ford Explorer, which was then hit by Ford Freestyle vehicle, according to the patrol report.

The vehicle was traveling approximately 100 mph on the wrong side of the highway before the collision.

The driver of the Camaro suffered "major injuries," and two of her passengers were killed. Four people from the other two cars were also killed, according to the patrol.

The driver was arrested for suspicion of driving under the influence of alcohol, causing "great bodily injury and death" and for manslaughter, according to Reuters.
