A vehicle service ramp including a ramp member having an inclined rear wall and a horizontal top wall. A slot extends along the rear wall and the top wall through which an arcuate chocking member protrudes slightly. The chocking member pivots as a vehicle tire ascends the rear wall and engages the front or rear ends of the chocking member. A rotatable shaft is mounted within the ramp member and includes a bent portion for engaging a fork on the chocking member allowing a user to manually pivot the chocking member. The shaft further includes a locking device for locking the chocking member about a vehicle's tire. An alarm also alerts a user whenever the chocking member pivots such as when the vehicle is descending or ascending the ramp member.
