  1. *<0.05; **<0.01.
  2. Factor 1: Speeding (>20 km/h), Speeding (>30 km/h), and Sudden steering.
  3. Factor 2: Running red lights, Ignoring stop signs, Lane departures, and Traffic violations occurring within intersections.
  4. Factor 3: Distracted driving.
  5. Trail making test A: TMTA; (a) Continuous performance test: Correct answer rate: CPT:C; Continuous performance test: Reaction time: CPT:R; (b) Continuous performance test: Coefficient of variation: CPT:C; Wechsler memory test (visual memory I): WMS; Zoo map tests: ZMT; Useful field of view UFOV.
  6. Control variables: Education, TMTA, CPT: Reaction time, WMS, ZMT, and UFOV. Bold values indicate statistical significance.
