Must a vehicle carrying 100 pounds of Division 4.3 dangerous-when-wet material stop at railroad crossings?
Detailed Explanation
A placarded vehicle must stop at railroad-highway crossings unless a specifically listed exception applies. This topic appears in the New York DMV CDL-10 review for Section 9.6.
Official reference: New York CDL-10, Placard Table 1 and Section 9.6.13Correct Answer: Yes, because the vehicle requires HazMat placards
Why This Matters on the CDL Test
Connect placarding rules to crossing procedures.
How to Remember It
Hazard division matters, not just pounds.
Answer Review
Division 4.3 requires placards for any amount; the small load does not remove the usual railroad stop requirement.
Why the other answers are weaker
- No, because the load is below 1,000 poundsThat is not the placarding threshold for Division 4.3.
- Only when the crossing has gatesGates do not determine the placarding requirement.
Test-Day Checklist
- Read the question once for the topic, then read it again for the exact CDL action being tested in General Knowledge.
- Eliminate answers that sound convenient but skip an inspection, warning sign, or safety step.
- Say the correct rule out loud before moving on so you can recognize it when the exam changes the wording.
