Prevalence, precision, and road safety implications of using faulty speedometers among commercial drivers in Ghana

Vehicular speed is a significant risk factor for road crashes globally. The first objective was to establish the proportion of motorists who drive with faulty speedometers. Second, study sought procedures used determine speeds when speedometers are defective. third precision which driving Convenience sampling interview 124 professional drivers at 16 bus terminals in Kumasi understand their speeding behaviors and perceptions on accuracy using defective Secondly, were purposively nested real-life tests self-reported concurrently compared actual measurements made android-speedometers. Results show that 58% Ninety-six percentof confident they could precisely tell travelling through such as experiences, personal judgment, intruding wind, engine sound, poking hands outside cars, thereby underestimating speeds. In tests, mean (58.7 ± 5.2 km/h) significantly lower than measured (64.6 8.9 km/h; p = 0.0003). This research has implications safety enforcement, education, advocacy.
