Driving, Parking & Emergency Response
22 free questions, part of the Hazmat (H) Endorsement CDL practice test
Parts 397 and 392 of the federal rules set how far a placarded vehicle has to stay from the road when parked, when you must stop at railroad crossings, and how long a load can sit unattended. ELDT.io's free bank covers all 22 driving, parking, and emergency-response questions with real scenario-based situations, not just dry rule recitation.
This topic has 22 questions, split into 2 tests of 11-11 questions each:

How close to the road can I park a placarded truck?
Under 49 CFR 397.7, you cannot park within 5 feet of the traveled part of the road or the shoulder, except briefly for loading, unloading, or an emergency, and you still have to use warning devices.
Do I have to stop at every railroad crossing if my truck is not placarded?
No. The mandatory stop-look-listen procedure in 49 CFR 392.10 applies to placarded cargo tanks and certain other vehicles regardless of load, but an unplacarded straight truck carrying only a trace amount is generally not required to stop unless it falls into one of the listed categories.
