Cross traffic legs for a dock leveler having a ramp mounted for pivotal movement between inclined, declined and cross traffic positions include first leg members mounted for pivotal movement on the ramp and second leg members which are supported on and moveable with respect to the first leg members to allow positioning the ramp in a below dock position. Leg lock members are supported for pivotal movement on the first leg members between working positions engageable with the second leg members to support the ramp in a cross traffic position and retracted positions out of engagement with the second leg members to allow the dock leveler ramp to move to a below dock position. The leg lock members are connected to an extension lip pivotally mounted on the ramp so that, as the lip is extended, the lock members are moved out of engagement with the cross traffic legs. A lock pin is engageable with one of the lock members to prevent unwanted lifting of the lip when the ramp is in a stored, cross traffic position.
