A three-vehicle crash Friday afternoon blocked lanes of Interstate 15 just south of Temecula and sent one person to a local hospital, but no serious injuries were reported. The crash happened a little after 2:30 p.m. on northbound I-15 near the Border Patrol checkpoint, just north of the Riverside County line. Authorities blocked the three left lanes of northbound I-15 in the area while responding to the crash, snarling traffic back to Bonsall. An ambulance took one person to a hospital for a complaint of pain, according to California Highway Patrol Officer Mike Lassig. Lanes were reopened by about 3:40 p.m. Will Fritz can be reached by email at email@example.com.
