Three people were killed Saturday in vehicle-related collisions, proving that even on well-marked roads in broad daylight, what police term 'the human factor' continues to exact a heavy price. On Saturday morning, 68-year-old Nellie Krichevsky was killed and seven others injured in a frontal collision between two vehicles at the Silver Junction on Road 4. The apparent cause of the collision was the failure of one of the two vehicles to stop at a red light at the busy intersection. Krichevsky, a resident of Rishon Lezion, her husband, and another two passengers in the car were all en route to a vacation at the Dead Sea. Instead of enjoying the mineral waters, Krichevsky's passengers and four others were all taken in good condition to Ashkelon's Barzilai Hospital. Less than an hour later, Hod Hasharon resident 46-year-old Shimon Sforin was fatally injured when the bicycle he was riding was hit by a commercial vehicle on Highway 5. The collision occurred near the Ramat Hasharon tennis courts, when the commercial vehicle suddenly swerved to the right, hitting Sforin, who was riding on the shoulder of the road. Sforin suffered massive injuries and was taken by an MDA rescue team to The Rabin Medical Center - Beilinson Campus in Petah Tikva, where he died as a result of his injuries. The vehicle's driver was detained for investigation by Tel Aviv District Traffic Police. In the early afternoon, a third fatal collision occurred on Highway 90 at Amiad Junction, south of Safed. A vehicle that was traveling southbound on the major highway swerved, killing one woman and injuring three others. A Jordan Valley MDA team was rushed to the scene and evacuated the three victims to Rebecca Sieff Hospital in Safed, where they were hospitalized in serious, moderate, and good condition, respectively.
