What should a combination vehicle driver prioritize when changing lanes?

When changing lanes, a combination vehicle driver should prioritize clear space and signaling. This is crucial for maintaining safety on the road. Before executing a lane change, the driver must ensure there is enough space in the adjacent lane to maneuver without encroaching on other vehicles' paths. This involves checking mirrors, blind spots, and ensuring that the lane is not too narrow or occupied.

Signaling is equally important, as it communicates the driver's intentions to other road users. This helps prevent accidents and promotes smoother traffic flow, as other drivers will be aware of the driver's movements. Prioritizing these actions reflects responsible driving practices that enhance safety for everyone on the road.

Fuel efficiency and passenger comfort, while important considerations for driving in general, do not take precedence when it comes to the critical action of changing lanes. Likewise, the speed of the maneuver should be controlled to ensure safe execution rather than being the driving factor.
