Route 144 begins in the west at an intersection with Route 22A east of Benson. The route follows a generally east-northeast track as it heads out of Benson, crossing into Sudbury and ending at an intersection with Route 30 south of town. Route 144 runs through an isolated area, intersecting one relatively major local road, Hortonia Road, along its length, but not intersecting any numbered routes between its endpoints. The road passes by Lake Hortonia just before ending at its eastern terminus.
