What action should a driver take if they feel unwell before or during their shift?

If a driver feels unwell before or during their shift, the appropriate action is to notify a supervisor and refrain from operating the vehicle. This is crucial for several reasons.

First and foremost, operating a vehicle while unwell poses significant safety risks not only to the driver but also to passengers, emergency personnel, and other road users. A driver's ability to safely control the vehicle and respond to dynamic conditions can be impaired by various ailments, whether they are physical or mental.

Additionally, informing a supervisor allows for proper assessment and management of the situation. The supervisor can make informed decisions about staffing and ensure that the shift continues safely without compromising operational efficiency or safety protocols.

Continuing duties as normal may lead to poor performance and increased chances of accidents or errors, while taking medication could further impair driving abilities. Waiting for a fellow crew member's input can delay necessary action and leave critical safety decisions to someone who may not be trained to evaluate the driver's fitness to work. Therefore, notifying a supervisor and stepping back from the role until assessed is the most responsible and safe approach.
