Railroad Pavement Markings
Pavement markings, consisting of an X and RR, may be painted on the pavement at the approach to some crossings. When approaching railroad tracks, be alert. Trains may approach the crossing at any time and from either direction. Unless you can clear the tracks completely, never start across the tracks. Make sure there is room for your vehicle on the other side of the tracks before proceeding.
Note: School buses must always stop at railroad crossings, even when the lights are not flashing.
