What is one responsibility of the DOT technician regarding the distributor truck?

The responsibility of checking spray nozzles and settings is crucial because it directly affects the quality and effectiveness of asphalt application during road construction and maintenance. The distributor truck is used to apply liquid asphalt materials uniformly and efficiently. Therefore, ensuring that the spray nozzles are functioning correctly and set to the appropriate settings is essential for achieving proper coverage and adhesion to the road surface. This task helps in maintaining the quality of work and preventing issues such as uneven surfaces or improper bonding of layers, which can lead to premature road deterioration.

While other tasks, such as adjusting tire pressure, refueling the truck, or dumping old asphalt, are also important for maintaining operational efficiency and safety, they do not specifically pertain to the specialized function of the distributor truck in roadway applications as checking the spray nozzles and settings does.
