Why is it important to obey stop signs or flashing lights at railway crossings?

Obeying stop signs or flashing lights at railway crossings is critical primarily because trains are fast, heavy, and cannot stop quickly. Unlike vehicles, trains have a significantly longer stopping distance due to their mass and the physical limitations of their braking systems. A train traveling at high speed can take over a mile to come to a complete stop after the brakes are applied. This means that if a vehicle attempts to cross the tracks while the warning signals are active, there is a high risk of collision, which can result in severe injuries or fatalities not only for those in the vehicle but also for train passengers and crew.

Additionally, the rules around railway crossings are designed to prevent accidents and enhance safety for all road users. By obeying these signals, drivers help ensure their own safety as well as that of others using the road and railway.
