The unit begins with an online lesson, during which information will be presented on the causes and major types of railroad crossings, along with procedures for safely encountering crossings.
Railroad-highway crossings can also cause problems, particularly when pulling trailers with low underneath clearance. These trailers can get stuck on raised crossings; Low slung units (lowboy, car carrier, moving van, possum-belly livestock trailer), Single-axle tractors pulling a long trailer with its landing gear set to accommodate a tandem-axle tractor.
There are multiple types of railroad crossings: passive, active and highway crossings. Each type uses a variety of traffic control devices.Some have yellow circular advance warning signs, pavement markings and crossbuck warning signs.
