Idaho Railroad Crossing Laws
Under federal law, placarded hazmat loads and passenger buses must stop at every Idaho grade crossing, 15 to 50 feet from the nearest rail (49 CFR 392.10). Idaho school buses stop loaded or empty (Idaho Code 33-1508). When a stop is required, Idaho sets that same window and bars driving around a lowered gate (Idaho Code 49-648); cross in one gear, never shifting on the rails (49-649). Every other truck slows and checks (49 CFR 392.11). A conviction stacks a CDL disqualification of 60 days or more (49 CFR 383.51).
A detail here is flagged medium confidence — confirm with the state DMV or the FMCSA rule before you rely on it.
How Idaho handles grade crossings
Under federal law, placarded hazmat loads and passenger buses must stop at every Idaho grade crossing, 15 to 50 feet from the nearest rail (49 CFR 392.10). Idaho school buses stop loaded or empty (Idaho Code 33-1508).

Every other truck slows and checks (49 CFR 392.11). A conviction stacks a CDL disqualification of 60 days or more (49 CFR 383.51).
Who stops, how far, and the CDL risk
- Who must stop: Placarded + buses
- Stop distance: Stop within 50 feet but not less than 15 feet from the nearest rail (Idaho Code 49-648), the same window as the federal rule (49 CFR 392.10).
- Clearance rule: Do not enter a crossing unless you can drive completely across without stopping. Cross in one gear and do not manually shift gears while on the tracks (Idaho Code 49-649). Never drive around a lowered gate or barrier (Idaho Code 49-648).
- Fine & CDL disqualification: A grade-crossing violation is an infraction under Idaho's rules of the road (Idaho Code 49-648, 49-649); expect a set fine plus court costs. The heavier penalty is federal: an FMCSA CDL disqualification of 60 days for a first offense, 120 days for a second within 3 years, and at least a year for a third (49 CFR 383.51), stacked on the state ticket.
