At approximately 17:30hrs units were dispatched to the area of Avenue E. and Colony Lake Estates in unincorporated Fort Bend County for the reported motorcycle vs car MVA. While still responding, Quint 22 (OIC J. Brownson) was advised of CPR in progress by bystander. Upon arrival size-up revealed a sport bike that had struck the rear of a car with the rider down in the roadway in the care of FBCEMS Medic #10. Upon conferring with the crew of Medic #10 the patient was determined to be a non-transport and personnel set about assisting with traffic control and securing hazards. Upon arrival of Stafford PD and FBCSO, the scene was turned over and units returned to service.
