* Personal preference: Just like anyone else, some people are naturally neater than others.
* Time constraints: Truckers have demanding schedules, and cleaning might not always be a priority.
* The type of trucking: Over-the-road drivers might have less time and opportunity to clean compared to local drivers.
* Pride in their work: Some drivers take pride in their rigs and consider a clean truck a reflection of their professionalism.
So, there's no single answer. You'll find a wide range of cleanliness levels in truck cabs.
