A spotter in auto racing is a trained team member whose job is to relay information to their driver, keeping them alert of what is occurring on the track. They are typically positioned higher, atop one of the grandstands or other support buildings, to see the entire track. Spotters keep in constant contact with their drivers via two-way radio communication. Spotters are considered the drivers' "eyes" and are one of the more notable yet simple, safety measures adopted by professional auto racing in the past two decades.
