HE HAD ALSO STATED THAT THE WINDSHIELD HAD BECOME FOGGED DURING THE TAXI TIME, WHICH RESTRICTED HIS ABILITY TO SEE. THE PIC DID NOT CONFIRM THAT STATEMENT IN HIS REPORT OF THE ACCIDENT. THE PIC STATED THAT THE VEHICLE, WHICH WAS A STREAMROLLER, WAS BACKING ONTO THE TAXIWAY AND HE SWERVED TO AVOID IT. THE ACFT'S LEFT WING TIP STRUCK THE LARGE ROLLER OF THE VEHICLE. THE PIC HAD STATED THAT HE WAS AWARE OF THE MOVEMENT OF THE VEHICLE, BUT DID NOT EXPECT IT TO MOVE ONTO THE TAXIWAY. THE OPERATOR OF THE ROLLER COULD NOT BE REACHED FOR COMMENT.
