The sample was the sum of two previous study samples from 2007 and 2014 (n = 2113). The study found that traffic violators were higher in adaptive impulsivity and that 5-HTTPLR La/La homozygotes were more likely traffic violators. A polymorphic interaction of 5-HTTLPR+C(-1019)G showed that contrary to the hypotheses, La/La+G/G genotype carriers were more likely to speed while S allele+C/C genotype carriers were least likely to violate traffic law which may point to an interactive effect on the desensitization of 5-HT1a autoreceptors.engopenAccessAttribution-NonCommercial-NoDerivatives 4.0 International5-HTTLPRC(-1019)Ggeenipolümorfismidliiklusrikkumisedimpulsivitygene polymorphismsüliõpilastöödimpulsiivsustraffic violationsThesis
