True or False: After a train clears a crossing with flashing signals, drivers may proceed after checking for a second train.

The statement is true because after a train has cleared a crossing and the flashing signals have stopped, drivers can proceed, provided they exercise caution. It is critical for drivers to check for any additional trains that may be approaching, as trains can run on different schedules and tracks. This precaution ensures that drivers don't enter the crossing while another train is coming, maintaining safety on the road.

The practice of waiting to check for a second train is part of safe driving behavior around railroad crossings. This does not imply that drivers must wait for a specific duration, such as a minute, nor does it suggest that drivers can never proceed. While it is essential to follow the signals, once they are no longer flashing, the driver is allowed to move forward with the understanding that thorough vigilance for any additional trains is necessary. Thus, the statement accurately reflects safe driving practices in relation to railroad crossings.
