A cart (10) facilitates collection, storage and distribution of folding warning lines (200). The cart (10) includes a framework (12) with a rolling support (100) to allow mobility and a stabilizer (120) to engage a work surface. The framework (12) has a handlebar (110), which enables the framework (12) to be tilted rotationally about the rolling support (100) and pushed. The framework (12) has a storage area ( 18) located between first and second sides (14, 16) and for receiving rigid members (201) of the folding warning lines ( 200). A plurality of notches (70) defined in a top member ( 32) and a plurality of slots (72) defined in a bottom member (48) of the framework (12) are adapted to receive and constrain the rigid members (201) in the storage area (18). The framework (12) has a holder (78) adapted to hold a flaccid member (202) of the folding warning lines (200). When the framework (12) is in an immobile position, the first and second sides (14, 16) are at a retention angle to gravitationally hold the rigid members (201) in the storage area (18). A retainer (130) constrains the rigid members (201) when the framework (12) is mobile.
