This invention detects, indicates and records road surface deviations in the normally-traveled vehicle tracks. Surface deviations detectable range from less than one inch in height to the largest height negotiable by the vehicle carrying the instrument. Final measurements are indicated from a mean surface, and with proper calibration numerical values may be established to give a meaningful quantitative description of the roughness of a given section of road.
