What are drivers required to do at a railroad crossing with no signals in Iowa?

In Iowa, when drivers approach a railroad crossing that has no signals, they are required to stop and look for trains. This law is in place to ensure the safety of the driver and passengers, as well as to prevent accidents that could occur due to the presence of an oncoming train. Stopping allows the driver to visually inspect the tracks for any trains before proceeding, which is critical since trains can approach quickly and unexpectedly.

The requirement to stop and look is particularly important for crossings without signals because the absence of warning signs means there are no automatic indicators of a train's approach. Thus, taking the time to stop and assess the situation is essential in promoting safe driving practices at these potentially hazardous intersections. By adhering to this rule, drivers can significantly reduce the risk of collisions with trains.
