This type of crossing does  not have any type of traffic control device. You  must stop at these crossings and follow proper  procedures. However, the decision to proceed  rests entirely in your hands. Passive crossings  require you to recognize the crossing, search for  any train using the tracks and decide if there is  sufficient clear space to cross safely. Passive  crossings have yellow circular advance warning  signs, pavement markings and crossbucks to  assist you in recognizing a crossing.  Active Crossings. This type of crossing has a  traffic control device installed at the crossing to  regulate traffic at the crossing. These active  devices include flashing red lights, with or without  bells and flashing red lights with bells and gates.  10.4.2 – Warning Signs and Devices  Advance Warning Signs. The round, black-on- yellow warning sign is placed ahead of a public  railroad-highway crossing. The advance warning  sign tells you to slow down, look and listen for the  train, and be prepared to stop at the tracks if a train  is coming. See Figure 10.5.  Figure 10.5  Pavement Markings. Pavement markings mean  the same as the advance warning sign. They  consist of an “X” with the letters “”RR” and a no- passing marking on two-lane roads.  There is also a no passing zone sign on two-lane  roads. There may be a white stop line painted on  the pavement before the railroad tracks. The front  of the school bus must remain behind this line  while stopped at the crossing. See Figure 10.6.  Figure 10.6  Crossbuck Signs. This sign marks the crossing. It  requires you to yield the right-of-way to the train. If  there is no white line painted on the pavement, you  must stop the bus before the crossbuck sign.  Section 10 – School Buses  Page 10-7
