The statement regarding short-term or daily rental truck drivers is accurate because these drivers may not have experience operating larger vehicles, especially in the specific conditions prevalent in commercial driving. This lack of familiarity can lead to issues such as poor spatial awareness and difficulty with handling the vehicle, particularly in situations where limited visibility is a factor. As a result, these drivers can pose a hazard to themselves and other road users.
In contrast, while some drivers may use turn signals, it's not guaranteed that they will execute the turn as indicated. Factors like distraction or miscalculation can influence their actions. Additionally, while many mail or delivery truck drivers are professionals, it is important to remember that any driver can pose a hazard under certain conditions, regardless of their occupation. Thus, the assertion that they do not pose a hazard is overly simplistic and not necessarily true in all driving scenarios.
