Stock car raicng action kicked off this weekend with the NASCAR Craftsman Truck Series on Friday, followed up by the Xfinity Series' visit to Nashville Superspeedway on Saturday. The prequel to Sunday's Cup Series came in the form of the Tenessee Lottery 250, which treated fans to a myriad of yellow-flag periods, and an overtime restart finish.While Kaulig Racing's AJ Allmendinger managed to take a trip to victory lane in Music City after a chaotic race, the first and second stages of the 250-mile-long event saw numerous caution-flag periods. With 15 cars out of 38 being involved in incidents before Stage 2 came to an end, many in the fraternity got talking on the 'cautions breed cautions' topic once again.NASCAR Xfinity@NASCAR_XfinityThe #TNLottery250 is underway from @NashvilleSuperS but we have trouble in Turn 1!21046The #TNLottery250 is underway from @NashvilleSuperS but we have trouble in Turn 1! https://t.co/FkpftHZqMLFans of the sport also had their fair share of reactions on social media.
