A vehicle canopy includes a vehicle body defining a roof opening. A roof is connected to the vehicle body across the roof opening. A headliner is supported by at least one of the vehicle body and the roof. A frame is supported by the vehicle body. A fabric partition is engaged with the frame and extends across the roof opening between the headliner and the roof. The fabric partition may assist in preventing occupant test dummies and/or other objects from moving through the roof opening.
