A raised pavement marker (RPM) is a small device attached to the road and used as a positioning guide for drivers. RPMs used on TxDOT roadways are reflective to be easily seen. Examples of lane markings that use RPMs include: broken lane lines, double yellow lane lines, exclusive turn lane lines and wrong-way arrows.
