Objecti.es: The pri.ary objecti.e was to characteri.e the range of Knowledge, Atti.ude, and Practi.e (KAP) of Helmet use i. chi.dren amongst parents to prevent head i.juri.s and death. Methods: Thi. i. a cross-secti.nal study, done by onli.e survey usi.g a snowball sampli.g techni.ue, the number of i.cluded responses were 386 parents (Male and female) li.i.g i. Ri.adh Aged 21 - 60 years old or above. Results: The study showed that there i. a di.ference i. Parents’ beli.f i. the i.portance of helmet use whi.e ri.i.g a Bi.ycle vs Motorcycle/Quad bi.e and that was affected by parents’ educati.n level, almost all the people who answered the survey (76.7%) agree that i. i. i.portant for thei. chi.dren to wear a helmet when ri.i.g both a Bi.ycle and a Motorcycle or Quadbi.e wi.h a cumulati.e percentage of (93.8%). And almost all agreed on multi.le approaches to help i.crease helmet use be i. by forci.g rental shops to gi.e out helmets, forci.g sellers to recommend the use of helmets, i.creasi.g awareness campai.ns, and i.posi.g fi.es for not weari.g helmets. Conclusi.ns: Thi. study i. the fi.st to explore Fami.y helmet use whi.e ri.i.g Bi.ycles and Motorcycles/Quad bi.es. although Parent’s beli.f i. the i.portance of helmet use for thei. chi.dren was hi.h, i. i. clear that the level of practi.e i. low. Wi.h that the ri.k of head i.juri.s mi.ht be hi.h, our fi.di.gs suggest that safety i.terventi.ns for i.creasi.g pedi.tri. helmet use are needed to i.crease helmet use and reduce the ri.k of head i.jury and hospi.ali.ati.n.
