Ten-Hour Break with Division 1.3G Fireworks
You are hauling 8,000 lb of Division 1.3G consumer fireworks in a 53-foot van, 400 miles into a 600-mile run. It is 11:40 p.m. and you have driven 7 hours, so a 10-hour break is due. At exit 112 you find three choices. (A) The paved shoulder of the on-ramp, where the white fog line is 4 feet from your left mirror. (B) A 24-hour truck stop with a large lot; the only open space is 250 feet from a diner that stays open all night. (C) A fenced, gated, lighted lot behind a chemical plant's guardhouse, 340 feet from the guardhouse and well off any public road. Your co-driver is asleep in the sleeper berth. The next exit with services is 45 miles away and you have 40 minutes of legal driving time left.
1. Choose a location and explain why the other two are not legal for a 10-hour break with this load.
Read the worked answer
Division 1.1, 1.2 and 1.3 explosives carry two hard parking limits: never within 5 feet of the traveled portion of a public street or highway, and never within 300 feet of a bridge, tunnel, or building where people live, work, congregate or assemble.
- (A) On-ramp shoulder, 4 feet off the fog line - fails the 5-foot rule outright. It also puts 8,000 lb of 1.3G explosives where traffic merges at highway speed, which is the situation the rule exists to prevent.
- (B) Truck stop, 250 feet from an occupied all-night diner - fails the 300-foot rule. The diner is a building where people congregate, and people are in it at 12:30 a.m. Note that "250 feet" is close enough that a fire or a blast would put those people at risk, which is the point of the measurement.
- (C) Fenced, gated, lighted lot behind the guardhouse, 340 feet away - clears both numbers. The guardhouse is a workplace building, but 340 feet exceeds 300, and the tractor-trailer sits well off any public road. Gated, controlled access also matters for the attendance question.
Take (C).
2. You want to sleep. What does "attending" this vehicle require, and does the answer change depending on which lot you chose?
Read the worked answer
A vehicle carrying Division 1.1, 1.2 or 1.3 explosives must be attended at all times unless it is parked in a secure, controlled facility. Attending means a qualified person is within 100 feet of the vehicle, has it in clear view, with the engine off and the brakes set. That person has to be awake and aware - a co-driver asleep in the sleeper berth is not attending, no matter how close he is physically.
This is what decides the case as much as the distance numbers do. In lot (C), the fence, the gate and the controlled access make it a secure facility, so the attendance requirement is satisfied by the facility itself and you can legally sleep for 10 hours. In (A) or (B), secure parking is not available, so the only way to comply would be to stay awake and within 100 feet with the rig in view for the entire 10-hour break - which is not a realistic plan and would put you back on the road severely fatigued.
Final answer: park in (C); the secure lot is what makes the 10-hour break possible at all.
3. At the gate the guard says no overnight parking, and you are down to 35 minutes of legal driving time. What are your options?
Read the worked answer
You cannot drive past your hours hunting for a better spot, and you cannot fall back on (A) or (B) without solving the attendance problem. Work the problem in order:
- Negotiate in place. Ask the guard to call the plant's shipping office or security supervisor. Shippers who handle hazmat frequently have a designated area for this and the guard may not know about it.
- Call dispatch. The carrier is responsible for providing a legal place to stop; dispatch may know a secure lot or a customer nearby that accepts parked hazmat equipment.
- Re-examine (B). If the lot is large, park on the far side, well past 300 feet from the diner. That fixes the parking rule but not attendance - so you would still need to stay awake and within 100 feet in view, or have a relief driver who is awake do it.
- Do not creep up on the limit. Stopping early in a legal spot beats running out of hours on a ramp with 8,000 lb of 1.3G aboard.
What you never do is park on the shoulder of a live traffic lane and go to sleep.
