Which of the following is a recommended safety practice for for-hire vehicle drivers?

Carrying a first aid kit is a recommended safety practice for for-hire vehicle drivers because it ensures that the driver is prepared to provide immediate assistance in case of an accident or medical emergency. Having a first aid kit on hand allows drivers to address minor injuries and stabilize passengers until professional medical help arrives. This readiness not only helps in maintaining passenger safety but also demonstrates a commitment to providing responsible and secure service.

The other options do not align with safe practices. Driving without a seatbelt compromises both the driver's and passengers' safety, as seatbelts are essential in minimizing injury during an accident. Ignoring passenger requests can lead to unsafe situations or dissatisfaction and may reflect poorly on the driver's service. Using only personal routes limits the ability of drivers to navigate efficiently and may prevent them from serving passengers effectively, especially in unfamiliar or high-demand areas.
