Failure to stop at a railroad crossing when required to do so can result in a _____ month license suspension
EleoNora [17]

The correct answer is 6 months. Failure to stop at a railroad crossing when required to do so can result in a 6 month license suspension.

Explanation:

Railroad crossings are too dangerous and risky. There are certain rules associated when crossing them. The railroads flag a red mark when the train is about to come and the traffic has to stop before the marked line. This is done for the security of public, as there can happen life threatening accident if the railroad crossing rules are not followed.

But if someone violates the crossing rules, or doesn't stop at the crossing despite of the red mark flagged or red light on, his license would be suspended for a minimum of 6 months. This is done because not stopping at a too risky way is serious crime which can result in a serious accident and may lead to the loss of lives.
