When winter turns to spring in New Jersey, there's always an uptick in the number of motorcycle crashes, with the two main reasons cited by state cops being "unsafe speed" and "driver inattention," NJ.com notes. Further down the list is "road/environmental factor," which appears to be what led to the death of a 41-year-old man Thursday on the side of Route 21 in Clifton, per another NJ.com report. The man, whom cops have yet to publicly identify, was cruising north on his Yamaha a little after 4pm when he hit a refrigerator left lying in the shoulder near an entrance ramp. He was killed. The crash closed the northbound side of Route 21 for hours after. Police are trying to find out the owner of the abandoned fridge. (More New Jersey stories.)
