A.J. Allmendinger’s team had to go old school after having radio communication issues at the Echopark Automotive Grand Prix at Circuit of the Americas in Austin, Texas on Sunday.
Allmendinger won the Xfinity Series race on Saturday, and his No. 16 Chevrolet was running in the top 10 late in Sunday’s Cup Series race.
Allmendinger’s Kaulig Racing team resorted to writing messages using red tape placed against a sign in order to communicate with him.
