Drowsy Driving, Parking, and a Dark Railroad Crossing
You are driving a placarded tractor-trailer from Chicago to Springfield, Illinois, with 1,800 lb of UN1263, Paint, Class 3, PG II, and 600 lb of UN1789, Hydrochloric acid, Class 8, PG II. It is 11:30 p.m., and you have been driving since 6 a.m. You feel drowsy. The next exit has a rest area with truck parking 3 feet from the traveled lane of the access road; a closed weigh station 1 mile ahead with a paved lot 50 feet from the highway; and a 24-hour truck stop 8 miles ahead. Before the truck stop you must cross a railroad crossing with flashing red lights that are dark and a stop sign. A sign at the crossing says 'No gates.'
1. Where should you park, and what parking rules apply to hazardous materials?

Do not park on the shoulder or within 5 feet of the traveled portion of a road. The rest area space 3 feet from the access road fails that rule if you leave the vehicle unattended. The closed weigh station is 50 feet from the highway and, if it is a legal parking area and the lot is safe, it is a better choice than the rest area. The truck stop is the best option if you can drive there safely, but you should not drive 8 miles while drowsy. The judgment is to stop at the first legal, secure place, likely the weigh station if permitted, set the parking brake, secure the vehicle, and notify dispatch. Do not park near open flames or where the vehicle can be struck. If the weigh station is posted no parking, use the truck stop or call for relief.
2. What must you do at the railroad crossing, and does the dark signal change the rule?
Read the worked answer
Because the vehicle is carrying placarded hazardous materials, you must stop before the railroad crossing, even if the flashing lights are dark. Treat a dark signal as a passive crossing: stop, look both ways, listen, and proceed only when you can clear the tracks without stopping. Do not stop on the tracks. If a train is coming or the crossing is blocked, stay back. The stop sign and the dark lights do not cancel the hazmat stop requirement. If a police officer or flagman directs traffic, follow their direction, but still verify the track is clear before moving. The purpose of the stop is to give you time to see and hear a train that the signal may not be warning you about.
3. Explain why this load is placarded, and how that affects the crossing decision.
Read the worked answer
Placards are required because the aggregate weight exceeds the 1,001-lb threshold for non-bulk packages: 1,800 lb of Class 3 plus 600 lb of Class 8 equals 2,400 lb. The load needs FLAMMABLE and CORROSIVE placards. That placarded status is exactly why the railroad-crossing stop applies. If the load were reduced below the placarding threshold, the crossing stop rule would not be triggered by hazmat, though a safe driver still checks the crossing. On this trip, keep the placards visible, carry the shipping paper and emergency response information, and do not remove placards to avoid the stop.
