Background: Risky driving is an error that causes the occurrences of road traffic accidents. The reason of risky driving is due to the low enforcement of traffic rules. The majority of crashes in Ethiopia are due to drivers’ error. Even though risky driving is the major cause of road traffic accidents, scientific evidence to show the factors of risky driving and why drivers engaged in risky driving is limited in Ethiopia. Objective: To assess the prevalence of risky driving and associated factors among Debre Tabor town drivers, Northwest, Ethiopia, 2020. Method: Cross-sectional study triangulated with qualitative study was used among 564 participants from November 30 to December 30/2020. Stratified sampling and purposive sampling techniques were used for quantitative and qualitative methods respectively. A self-administered questionnaire and interview method were employed. Epi-data version 4.6.0.2 and statistical package for statistical science version 23 were used for data entry and analysis respectively. The thematic method was used for qualitative data analysis. Frequency table and bar chart were used for descriptive analysis. Multiple binary logistic regression was employed to identify the factors at p-value <0.05. Result: The prevalence of risky driving was 82.1%. Drive at night (AOR=3.7, 95%CI; 1.6-8.4) compared to not drive at night , never attending religious organization (AOR=5.6, 95%CI; 1.9-16.4) as compared to attend daily, driving >8 hours/day (AOR=4.3, 95% CI; 1.43-13) as compared to <4Hr/day, think income not enough (AOR=8, 95%CI; 3.6-18.5) as compared to think enough, non-governmental-driver (AOR=0.147, 95%CI; 0.033-0.661) as compared to Bajaj drivers were significantly associated with risky driving. The socio-economic problem, less strict law enforcement, training institutions problem, drive at night, being bajaj drivers and poor faith were the reason for risky driving in the qualitative finding. Conclusions: Risky driving was high among drivers. Being non-governmental drivers were the protective factor of risky driving whereas never attending a religious organization, driving >8 hours/day, think income not enough and drive at night were the risk factor of risky driving. Except driving >8 hours/day, all factors were supported by the qualitative study. So traffic rules shall be strictly enforced. Key word: Associated factors, Debre Tabor, Risky driving, RTA.
