Answer:
If I approach a railroad crossing with a buck sign that has no lights or gates then the best and safest thing to do is to slow down and look in all directions to ensure that no train is coming in order to prevent an accident. If there is no train coming then I should proceed driving or cross the road. This is why over-speeding shouldn’t be encouraged because it takes a split second to make such safety decisions in order to steer clear from preventable accidents.
