What should a driver do when red lights are flashing at a railroad crossing?

When red lights are flashing at a railroad crossing, the driver must stop at the gates and wait. This is a crucial safety measure designed to prevent accidents that could occur if a vehicle were to attempt to cross while a train is approaching. The flashing red lights serve as a clear warning that a train is either coming or may already be on the tracks, and stopping provides enough time for the train to pass safely.

Waiting behind the gates is essential for the safety of everyone on the road. Trains take much longer to stop than automobiles, and attempting to cross while the lights are flashing could lead to a tragic collision. Additionally, the gates are lowered as an extra precaution to block vehicles from entering the tracks during that critical time.

In contrast to the other choices provided, stopping is a definitive action that enhances safety at railroad crossings, while speeding up or continuing to drive ignores the potential risks associated with oncoming trains. Looking for an alternative route is unnecessary when simple compliance with the traffic signals ensures safety. Therefore, waiting until it is clear and the lights have stopped flashing is the correct and safest action for any driver.
