Wyoming Oversize and Overweight Trucking Regulations - Safety, Signage, and Visibility Requirements

Navigating Wyoming’s Roads: Operating Hours and Travel Restrictions

Wyoming’s vast landscapes demand careful regulation of oversize vehicles. Operators must adhere to specific timeframes and conditions:

  • Daytime Operations: Oversize vehicles are permitted on roads from 30 minutes before sunrise until 30 minutes after sunset, every day of the week.
  • Night Travel: Loads up to 10 feet wide may traverse Interstate highways at night, provided they meet all other legal dimensions and employ proper lighting.
  • Holiday Considerations: While holiday travel is generally permissible for non-escorted loads, it’s crucial to note that ports of entry close during these periods. Advance permit acquisition is essential for holiday transit.
  • Seasonal Cautions: Be prepared for potential springtime restrictions, implemented to protect roads during snow and ice thaw.

Enhancing Road Safety: Essential Equipment for Oversize Loads

Prioritizing safety, Wyoming mandates specific signage, flags, and lighting for oversize and superload transports:

Signage Requirements

  • Placement: “Oversize Load” signs must be prominently displayed on both the front and rear of the vehicle.
  • Dimensions: Signs should measure at least 5 feet in width and 10 inches in height.
  • Design: Utilize a yellow background with black lettering. Letters must be a minimum of 8 inches tall and 1 inch wide.
  • Heavy Haul Provision: For heavy haul transports, escort vehicles must also display “Oversize Load” signage, visible from front and rear.

Flag Protocol

Fluorescent red safety flags are crucial for marking extended loads:

  • Attach flags to any overhang that extends beyond the trailer’s sides.
  • For overhangs exceeding 4 feet, ensure the extremity is flagged during daylight hours and illuminated at night.

Lighting Guidelines

Proper illumination is vital for nighttime operations:

  • Corner Markers: Install amber clearance lights on front corners and red clearance lights on rear corners.
  • Overhang Illumination: Any applicable overhang must be well-lit during night travel.
  • Warning Lights: Mount either a revolving amber light, amber strobe, or two-way flashing amber lights (minimum 4-inch diameter) on the vehicle.

Securing Your Journey: Wyoming’s Oversize Permit Process

Understanding Wyoming’s permit system is crucial for a smooth operation:

  • Validity Period: Standard permits are active for 5 days.
  • Extensions: An additional 5-day extension may be granted if adverse conditions prevented trip completion within the initial period.
  • Acquisition Method: Drivers must obtain permits directly from Ports of Entry.
  • Pre-arrival Protocol: Contact the Port/Scale at least one hour before arrival to receive a clearance number. Failure to do so may result in hefty fines and operational delays.

How to Obtain Your Permit
