We present results for the QUEST RR Lyrae Survey at low Galactic latitude, conducted entirely with observations obtained with the QUEST mosaic camera and the 1.0/1.5-m Jurgen Stock Schmidt telescope at the National Observatory of Venezuela. The survey spans an area of 476deg^2^ on the sky, with multi-epoch observations in the V, R and I photometric bands for 6.5x10^6^ stars in the Galactic latitude range -30{deg}<=b<=+25{deg}, in a direction close to the Galactic anticentre 190{deg}<=l~95 and ~85 per cent for RRab and RRc stars, respectively. Photometric metallicities were computed based on the light curves and individual extinctions calculated from minimum light colours for each RRab star. Distances were obtained with typical errors ~7 per cent. The RR Lyrae survey simultaneously spans a large range of heliocentric distances 0.5<=R_hel_(kpc)<=40 and heights above the plane -15<=z(kpc)<=+20, with well-known completeness across the survey area, making it an ideal set for studying the structure of the Galactic thick disc.
