What action should be avoided when crossing train tracks?

When approaching train tracks, crossing while the lights are flashing is a critical safety violation that should always be avoided. The flashing lights serve as a clear warning that a train is approaching and it is unsafe to cross. Ignoring this warning can result in dangerous accidents, as trains can travel at high speeds and may not be able to stop in time to prevent a collision once a driver has entered the tracks.

In the context of the other choices, stopping at the tracks may be necessary in certain situations, such as when a train is approaching or when instructed to do so by a traffic signal. Looking for trains before crossing is an essential and responsible action to take, ensuring that the tracks are clear before proceeding. Similarly, making sure it’s clear before attempting to cross the tracks is a fundamental safety practice. However, crossing when the warning lights are activated definitively puts individuals at risk and contradicts safe driving practices.
