The purpose of the study was to standardize the RT-2S brake reaction time tester as an alternative brake reaction timer to the American Automobile Association's (AAA) blue box that is no longer manufactured. Three hundred ninety-six subjects across the lifespan participated by using the RT-2S in a standard manner. Results were analyzed using the age groups used by AAA. Results indicated that male reaction times are faster, and as age increases, reaction times decrease. Although the RT-2S reaction times were slower than the norms for AAA, results suggest that the RT-2S is a reliable and valid tool for measuring simple brake reaction time.
