Disclosed is a device (100) and method (200) for measuring approach, departure and ramp over (ADR) angles of a vehicle. The vehicle is positioned on a four poster (150) for measuring the ADR angles using the device (100). The device (100) comprises a base column (90), at least one pair of first columns (80), at least one pair of second columns (70), a centre column (60), a plurality of brackets (50), a holder column (40), a rotating holder (30), a laser (20) and a digital angle measurement unit. The device (100) enables timely and efficient measurements of the ADR angles. The method (200) reduces efforts for doing measurement activities.
