Guides
The calculators give you the number; these give you the why. Longer reads on the math and rules drivers actually get burned by — written by a former CDL-A driver, checked against the regs, no fluff.
Sliding Tandems & State Bridge Laws
What one hole moves, the federal bridge formula, the 36-foot rule, and the kingpin laws — California's 40-foot rule and more — that change the answer at state lines.
→Cost Per Mile Mistakes Owner-Operators Make
Eight break-even errors that sink trucks: loaded-miles-only math, working for free, forgotten annual bills, no escrow, and trusting one good month.
→The 70-Hour Rule, Explained
The rolling window, recap hours at midnight, when a 34-hour restart beats running recaps, and the 8:45-a-day pace that never runs dry.
→Truck Payment Math Before You Sign
Why two deals with the same payment can differ by $23,000: amortization, APR vs payment, out-the-door costs, lease-purchase warnings, and the parking-lot checklist.
→Driver Per Diem in 2026
The $80/day rate, the 80% DOT rule, partial days, the tax-home trap, carrier per diem programs, and the ELD records that survive an audit.
Every guide pairs with a calculator, so the reading turns into a number you can use the same day: tandem slide, cost per mile, 70-hour recap, truck payment, and per diem.
