Understanding Colorado Oversize Permits and Their Importance
A Colorado Oversize Permit authorizes carriers to transport loads exceeding the state’s legal dimension and weight limits on public roads. These permits are indispensable for protecting Colorado’s infrastructure while keeping traffic safe. Permits issued are typically valid for five days and specify important operational conditions such as travel times and route restrictions.
Failing to obtain the proper oversize permits Colorado can result in hefty fines, costly delays, or even confiscation of loads. With Chicago Permit’s expert assistance, you can seamlessly comply with all Colorado oversize permits requirements and avoid such setbacks.
Key Colorado Oversize Permits Requirements
Colorado law specifies strict dimension and weight limits. Here’s a snapshot of critical limits when obtaining Colorado Oversize Permits:
Length: Up to 57′-4″ trailer and load on interstate highways; routine permits allow up to 130′ on four-lane highways.
Width: Maximum legal width without permit is 8′-6″. Loads wider than this require a permit.
Height: 14′-6″ on designated highways; 13′ on other routes.
Overhang: Up to 4′ front and 10′ rear allowed; any rear overhang exceeding 4′ must be properly lighted at night.
Weight: Maximum 80,000 lbs gross on interstate; 85,000 lbs on non-interstate roads. Specific axle limits apply (e.g., steer axle - 20,000 lbs, tandem - 36,000 lbs).
Super Loads: Loads wider than 17 feet or weighing over 200,000 lbs require extended approval times and additional surveys.
Operating times are generally limited from sunrise to sunset. Night travel is permissible under strict conditions loads up to 12′ wide can travel with proper lighting, while those between 12′ and 14′ wide require escorts.
