Rally cross, also commonly referred to as “RX”, is an entry level form of performance rally but without a navigator. Events take place on short courses and pretty much any type of car can enter. No special safety systems are required other than a helmet that meets the CARS regulations (the rally cross regs are available in the CARS Rule Book on their website).
There are four clubs in Ontario that are currently offering rally cross events. Please visit their websites for information about their events and supplemental regulations they may have:
