📖 Phase 1: Weigh Station & Weight Limits Lexicon
6 Spoken Concept Decks

Click on the speaker icons to listen and practice essential English for federal gross weight limits, PrePass bypass, sliding tandems, and scale master commands:

Federal Gross Weight Limits (80k / 12k / 34k / 34k) /ˈfɛd.ɚ.əl ɡroʊs weɪt ˈlɪm.ɪts/
23 CFR § 658.17: Maximum legal weights: 80,000 lbs Gross Vehicle Weight (GVW), 12,000 lbs steer axle, 34,000 lbs drive tandems, and 34,000 lbs trailer tandems.
"The commercial semi-truck scaled at 79,200 lbs gross weight with all three axle groups strictly under federal limits."
"Drive tandem axles must not exceed thirty-four thousand pounds on federal interstate highways."
PrePass & Drivewyze Electronic Bypass /priː pæs • ˈdraɪv.waɪz ˈbaɪ.pæs/
Windshield-mounted transponders communicating with roadside readers: Green light allows mainline bypass; Red light mandates pulling into the weigh station.
"The PrePass transponder gave a solid green light and double beep, authorizing us to bypass the port of entry."
"When your transponder signals a red light, you must immediately take the weigh station exit ramp."
Weigh-in-Motion (WIM) & 3-Pad Static Scales /weɪ ɪn ˈmoʊ.ʃən • ˈstæt̬.ɪk skeɪlz/
In-pavement piezoelectric sensors measuring axle weights at 60 MPH vs 3-platform static scales measuring steer, drive, and trailer groups independently.
"The highway weigh-in-motion sensors screened our axle weights dynamically as we approached the weigh station ramp."
"Pull onto the three-pad static scale at three miles per hour and bring the tractor to a smooth stop."
Sliding Trailer Tandems (250-400 lbs Per Hole) /ˈslaɪ.dɪŋ ˈtreɪ.lɚ ˈtæn.dəmz/
Repositioning the trailer sub-frame along the slide rail: Each pin hole shifts approximately 250 to 400 lbs between drive axles and trailer axles.
"Sliding the tandems forward four pin holes transferred one thousand pounds from the trailer tandems to the drive axles."
"Pull the pneumatic tandem lock handle and set the trailer emergency brakes before moving the tractor."
Federal Bridge Formula B & California 40-ft KPRA /ˈbrɪdʒ ˈfɔːr.mjə.lə • keɪ piː ɑːr eɪ/
Mathematical formula governing axle spacing to protect bridges; California and other states mandate max 40 feet from kingpin to center of rear tandem axle.
"In California, the distance from the kingpin to the center of the rear axle cannot exceed forty feet."
"The Federal Bridge Formula prevents excessive concentrated axle weight on interstate bridge spans."
Scale Master Commands & Paperwork Audits /skeɪl ˈmæs.tɚ kəˈmændz • ˈpeɪ.pɚ.wɝːk/
Scale intercom instructions and document inspections: Presenting Bill of Lading, cab card registration, IFTA tax decals, and DOT medical certificates.
"The scale master announced over the loudspeaker: 'Driver, park in the bypass lane and bring in your shipping papers.'"
"Present your physical commercial driver license, valid medical card, and current IFTA fuel tax credentials."
🔍 Phase 2: The Interactive Weigh Station Simulator
⚖️ 3 Real Scale Scenarios

🟢 1. Mainline WIM & PrePass Green Light Bypass

I-70 Eastbound Mile Marker 92 • 60 MPH Mainline Screen • PrePass Green Light • Gross: 78,800 lbs • Bypass Approved

🎙️ Phase 3: Scale Master & Commercial Driver Spoken Dialogue Trainer
Spoken Scale Intercom Roleplay Frames

Practice communicating with scale masters over loudspeakers, reading axle weights, and explaining tandem adjustments in English:

1. Scale Master Positioning Instructions

"Driver on the scale, please pull forward slowly and stop with your steer axle on pad one, drive tandems on pad two, and trailer tandems on pad three."

Driver: "Understood, Scale Master. Rolling forward at three miles per hour; all three axle groups positioned on the scale pads."
2. Announcing Axle Weights & Legal Compliance

"Scale Master, my steer axle is 11,800 lbs, drive tandems are 33,600 lbs, and trailer tandems are 33,900 lbs, totaling 79,300 lbs gross weight."

Scale Master: "Your axle weights and gross weight are fully legal under the Federal Bridge Law. Green arrow illuminated; you are cleared to roll."
3. Correcting Overweight Trailer Tandems

"Driver, your trailer tandems scaled at 35,400 lbs, which is 1,400 lbs over legal limit. Pull around to the bypass staging lane, slide your tandems forward, and re-weigh."

Driver: "Copy that, Scale Master. Pulling into the staging lane to slide tandems forward five pin holes to balance weight to the drives."
4. Re-Weighing After Sliding Tandems

"Scale Master, tandems are re-pinned at hole number six. New weights: Drives are 33,900 lbs and trailer tandems are 33,800 lbs."

Scale Master: "Scale display verified: 33,900 lbs drives and 33,800 lbs trailer. Perfect adjustment. You are legal; have a safe trip."
5. Presenting Credentials During Scale Audit

"Officer, here are my shipping papers: Bill of Lading matching 44,000 lbs freight, cab card registration, IFTA license, and my current DOT medical certificate."

Officer: "Everything is in order: Electronic logbook has available driving hours and IFTA credentials are valid. Take care out there."
⚠️ Phase 4: Weight & Bridge Law Dilemmas & Road Decisions
4 Real Highway Dilemmas
1. Overweight Tandem vs. California 40-ft KPRA Limit

Your trailer tandems weigh 34,800 lbs entering California. Sliding tandems back to hole 8 would balance weight to 33,500 lbs, but kingpin-to-rear-axle distance would measure 41 feet. What must you do?

2. PrePass Gives Green Light but Overhead Sign Says 'Must Enter'

Your in-cab PrePass transponder chimes green for bypass, but the static overhead highway DOT message board flashes 'ALL TRUCKS OVER 5 TONS MUST ENTER'. Which signal takes legal priority?

3. Tail-Heavy Cargo with Full Fuel Tanks (36,000 lbs on Trailer)

Shipper loaded dense steel pallets against the trailer rear doors. Even with tandems slid all the way forward, trailer tandems scale at 35,800 lbs while drives are only 28,000 lbs. How do you resolve this?

4. Scale Master Inspects IFTA Decal and Notes Expired Quarter

During a scale paperwork audit, the officer notices your physical door IFTA decal is from last year, though you carry the current annual certificate on your tablet. How do you respond?
