CDL disqualifications: Committing railroad-crossing violations while operating a commercial motor vehicle

What kinds of violations will result in this type of disqualification?

All drivers:
- Failing to have enough space to drive completely through the crossing without stopping.
- Failing to obey a traffic control device or the directions of an enforcement officer at the crossing.
- Failing to cross the tracks because of insufficient undercarriage clearance.
Drivers who aren't always required to stop:
- Failing to slow down and check that the tracks are clear of an approaching train.
- Failing to stop before reaching the crossing, if the tracks aren't clear.
Drivers who are always required to stop:
- Failing to stop before driving onto the crossing.

Pay a $35 re-qualification fee.
If disqualified for 1 year or more, pass the Commercial Driver License (CDL) knowledge and driving tests.
For a hazardous materials endorsement, pass a separate knowledge test. (We also may require you to show us a letter from the Transportation Security Administration stating you passed their background check.)

You may request an administrative review.
