CDL Hazardous Materials Practice Test

What must you do when driving across a railroad crossing?

1. Shift gears if necessary

2. Never shift gears while crossing tracks

3. Slow down and look around

4. Stop before the crossing

The correct answer is: Never shift gears while crossing tracks

When driving across a railroad crossing, it is essential not to shift gears while crossing the tracks. This is important for several reasons. First, shifting gears can cause your vehicle to stall, which may leave you stranded on the tracks during a critical time when a train could be approaching. In addition to the risk of stalling, changing gears can distract the driver, diverting their focus away from the crossing and any potential hazards, such as oncoming trains. Railroad crossings are often marked with signs and signals, indicating when it is safe to cross. By maintaining a consistent speed and avoiding gear changes, you can ensure your full attention is directed towards the crossing and assessing the environment for any danger. This practice enhances safety for both the driver and any pedestrians or other road users. The other options do not address the specific action required when approaching and crossing railway tracks as effectively as the chosen answer. While slowing down and looking around is a good practice before reaching the crossing, and stopping before the crossing has its own set of rules depending on the signals present, shifting gears during the crossing remains a safety concern that should be avoided.
