The Think campaign was launched with a bang at the Japan Automobile Research Institute (JARI) on 20 April, where a crash test simulating a rear-end collision at 35 km/h was performed to demonstrate the efficiency of head restraints to avoid whiplash injuries. About 20% of people involved in rear-end collisions later suffer from whiplash injuries. Although most people recover soon from the symptoms such as neck pain and stiffness, shoulder and back pains, dizziness, blurred vision, ringing in the ears and sleep disorder, some develop chronic pains and sometimes even disability. JAF will distribute campaign leaflets and tyre gauges until the end of the year and hold information activities on the main safety messages.
