CDL Hazardous Materials Practice Test

What should you do when required to stop at railroad crossings?

1. Stop and shift gears

2. Stop 15 to 50 feet before the nearest rail

3. Proceed immediately if no trains are visible

4. Only look for lights and sounds

The correct answer is: Stop 15 to 50 feet before the nearest rail

When approaching a railroad crossing, you should stop a safe distance before the nearest rail, typically between 15 to 50 feet, to ensure your vehicle is clear of any potential danger from passing trains. This distance allows adequate space for you to safely observe oncoming trains while also keeping your vehicle out of the way of any train that may be approaching. Stopping at this range gives you the best chance to adequately assess the situation, making sure the area is clear before proceeding. Factors such as visibility, the speed of the train, and the operation of warning signals can all be unpredictable, so ensuring a safe stopping distance is crucial for your safety and that of others. By doing this, you also allow any other vehicles or pedestrians to pass safely without creating a hazard at the crossing.
