What should a person doing maintenance on the road be cautious of?

The focus should be on pedestrians and other road users because they can be particularly vulnerable when road maintenance is taking place. Maintenance work often alters the normal flow of traffic, which can confuse both drivers and pedestrians. Workers might be present near the roadway, and unexpected movements can occur, increasing the risk of accidents.

During maintenance activities, it's essential to be vigilant about pedestrians who may not be familiar with the changes in the road layout and to also monitor other road users who might react unpredictably to the altered conditions. Maintaining proper communication through signage and barriers is crucial, but workers must also be actively aware of their surroundings to ensure everyone's safety.

While the other options are important considerations, the priority in a maintenance situation is the interaction with pedestrians and other motorists, as they represent immediate hazards that require careful attention.
