Transporting oversize or overweight loads at night is a complex but manageable task if you understand the rules and prepare thoroughly. In the U.S., nighttime hauling is tightly regulated, with each state imposing its own requirements. Improper lighting, missing escorts, or deviating from permit conditions can result in fines, cargo delays, or permit revocation.
We’ve compiled a comprehensive guide covering everything from lighting standards to state-specific rules, ensuring you can navigate nighttime transport confidently. Read on, follow our recommendations, and haul without issues!
Nighttime transport refers to moving oversize or overweight loads during dark hours, typically from 30 minutes after sunset to 30 minutes before sunrise. Many states restrict or prohibit such hauls, while others allow them under strict conditions like enhanced lighting, escorts, and explicit permit approval.
Reduced visibility at night increases risks, making compliance critical to protect drivers, cargo, and infrastructure. Non-compliance can lead to fines ($100 to thousands), cargo holds, or permit cancellation, impacting your schedule and reputation.

Tip. Always verify the permit includes “Night Travel Permitted” before planning a nighttime haul.
To haul oversize loads at night, you must strictly adhere to permit conditions and state laws. Here are the essential requirements:
Night travel permit. The permit must explicitly state “Night Travel Permitted.” Without this, moving after sunset is a violation, even for smaller oversize loads.
Lighting. Ensure the load is highly visible:
Red lights at the rear (visible ≥500 ft/150 m).
Yellow marker lights on the front and sides.
Red-and-white reflective tape outlining the load.
A yellow rotating or strobe beacon on the tractor with 360° visibility.
Flags at night. Replace daytime red/orange flags with red lights at the same locations (e.g., load corners or overhangs).
Escorts. Loads wider than 10 ft (3 m) typically require two escorts (front and rear), each equipped with yellow beacons.
Signs. “OVERSIZE LOAD” signs must be reflective or LED-lit for nighttime readability.
Weather and visibility. Transport is prohibited in fog, heavy rain, or snow if visibility drops below 500 ft (150 m), even with a permit.
Speed limits. Often capped at 45–55 mph (70–90 km/h). Maintain safe distances, especially in convoys.
Check all lights and tape for functionality and cleanliness before departure—dim or dirty lights can trigger fines.
Tip. Carry spare bulbs and reflective tape to address failures on the road.
Each state sets unique rules for nighttime oversize transport. Examples include:
Texas. Permitted for loads up to 12 ft wide with red lights, beacons, and escorts for wider loads.
Florida. Allowed with explicit permit approval, escorts, and illuminated signs.
California. Generally prohibited except for rare “superload” cases with special permits.
Georgia. Permitted for loads up to 10 ft wide with robust lighting.
Pennsylvania. Prohibited except for emergency services.
Oklahoma. Allowed with NM-1 permit and escorts for loads >12 ft wide.
Always check current regulations on state DOT websites or through services like omnipermits.com, as rules can change seasonally or due to road conditions.
Tip. Use omnipermits.com to confirm state-specific nighttime rules before submitting a permit application.
Safety. Nighttime visibility is lower, making oversize loads harder to spot. Proper lighting and escorts reduce accident risks.
Legal compliance. Violating permit conditions (e.g., missing lights or escorts) can lead to fines ($100–$5,000+), cargo delays, or permit revocation.
Efficiency. Accurate preparation speeds up permit processing (15 min–24+ hr) and minimizes roadside inspections.
Reputation. Compliance builds trust with clients and authorities, ensuring timely deliveries without legal issues.
Tip. Photograph the load with lights and signs before departure to prove compliance during DOT checks.
Verify the permit. Ensure “Night Travel Permitted” is clearly stated. If absent, contact DOT or omnipermits.com before moving.
Test lighting. Check all red/yellow lights, beacons, and reflective tape before departure. Carry spare bulbs and batteries.
Remove unnecessary markings. After the haul, cover or remove signs and lights on an empty trailer to avoid confusing inspectors.
Maintain communication. Use two-way radios (CB or UHF/VHF) to coordinate with escorts for real-time navigation.
Study the route. Some bridges, cities, or highways prohibit nighttime hauls. Verify with DOT maps or apps like Hammer or Trucker Path.
Monitor weather. Check forecasts and postpone travel if fog or heavy rain is expected, as visibility below 500 ft voids permits.
Hire professionals. For complex hauls, use omnipermits.com to secure permits and escorts efficiently.
Document setup. Take photos of the load with lights and signs for proof of compliance.
Plan for escorts. Arrange certified pilot cars in advance through DAT Load Board or omnipermits.com.
Train your team. Ensure drivers and escorts understand state rules and permit conditions to avoid errors.
Stock extra equipment. Keep spare red/yellow lights, reflective tape, and mounts in the cab for quick fixes.
Educate the crew. Drivers and escorts must know state-specific nighttime rules and how to read permits.
Use navigation tools. Apps like Hammer or Trucker Path help plan routes, but cross-check with the permit for accuracy.
Keep DOT contacts handy. Store state DOT numbers for quick clarification of nighttime restrictions.
With thorough preparation, nighttime oversize transport is safe and legal. Check your permit, ensure proper lighting, and plan your route carefully to haul smoothly!
