OMAHA, Neb. (AP) — Police say a 14-year-old Omaha boy was seriously injured over the weekend after his minibike collided with a vehicle.

Authorities say the teenager was traveling on his Reaper Choppers minibike Saturday night when he collided with a vehicle.

The teenager, who wasn’t wearing a helmet, was taken to the Nebraska Medical Center. Although his injuries are considered serious, authorities say they aren’t life-threatening. The vehicle’s driver wasn’t injured in the crash.

Police spokesman Sgt. Jason Menning says the minibike isn’t street legal. Menning says it didn’t have headlights, turn signals and taillights. The teenager was ticketed for negligent driving.
