Some sort of survey or test vehicle with the state DOT. Probably used with grading roadways for routine repair or replacement. It has 2 lasers in the rear on both sides and what looks like a suspension sensor and a front Ground Penetrating Radar or surface camera.
They are reflective too and vehicles like that don't usually do work on the road without two blockers with attenuators and a pickup with a message board.
NYS DOT has had those diagonal stripes for years. Maybe not as effective as chevrons but they've been doing their stripes for a lot longer than the recent chevron push.
