Do you need special permits this construction season?
Spring has sprung, and with the change in seasons come warmer weather, more flowers and wildlife, and of course, increased construction. If you are a construction company, or haul construction equipment, it is important to go into the busy season prepared.
Obtaining the proper permits
Each state has regulations on handling oversize or overweight (OS/OW) vehicle movements. These regulations indicate:
- When an over-dimensional or overweight permit is required; the types of permits available and their fees;
- Permit insurance requirements;
- Maximum permitted vehicle limitations;
- Sign, flag, light, and escort requirements; and
- Permit travel restrictions.
Before any trip involving an OS/OW load, it is important to check in on the expectations of each state and obtain the proper permits.
OS/OW rules are evolving
Last year, oversize/overweight permitting saw significant updates with movement windows, escort thresholds, and weekend/night travel allowances shifted in several states. At the same time, agencies are pushing for automation and harmonization, meaning more permits can be issued instantly, but thresholds still vary widely.
Electronic cab cards and permits gained traction in 2025, and many jurisdictions now accept digital copies. However, some states still require paper for OS/OW and specialty permits.
For instance, in many states digital cab cards are accepted for IRP and IFTA, but paper OS/OW permits are still mandatory in most places. Before departure, check your route and prepare both formats as needed. At this point, best practice is to carry both PDFs stored offline, and printed copies.
OS/OW permit mistakes to avoid
Many carriers, especially those managing permits in-house, fall into the same traps when applying for or managing permits. Watch out for these frequent errors:
- Inaccurate or incomplete vehicle/load information. Wrong axle weights, vehicle specs, or routing details can cause delays or invalid permits.
- Not applying on time. OS/OW permits often require extra processing time for route analysis or engineering reviews.
- Using expired or misused permits. Permits are often only valid for certain dates, times, and routes. Deviating from that voids the permit.
- Not understanding state-specific requirements. Every state has unique laws, including seasonal weight restrictions, travel curfews, and escort mandates.
- Not staying on top of state updates to OS/OW rule changes and automation rollouts. Staying informed will help dispatchers adjust plans quickly and avoid roadside delays.
- Failing to carry or display the permit as required. Some jurisdictions demand the permit be physically or digitally present and available on request.
Tips to staying compliant
Operating without proper permits can lead to violations which include fines of up to several thousand dollars, impoundment, being escorted off-route, and noncompliance points against your safety score.
Set yourself up for a successful construction season by doing your research well in advance to avoid running into obstacles that may impede your ability to operate on the requested dates. Verify which states require paper permits and which allow digital, and continue to monitor OS/OW rule changes and automation capabilities to avoid delays.
