“…Indeed, parents may be unaware of whether their children wear helmets. Ehrlich, Longhi, Vaughan, and Rockwell (2001) surveyed parents and children (aged 8-12) separately and found a significant discrepancy: parents stated children wore a helmet 90% of the time, whereas children estimated riding without one approximately 60% of the time. Similarly, Ehrlich, Helmkamp, Williams, Haque, and Furbee (2004) found 51% of children stated that they always wear helmets (compared to 70% of corresponding parents) and 20% of the children reported never wearing one (compared to 4% of corresponding parents).…”
