The maximum weight for a vehicle in California is determined by the type of axle it has. For example, a steer axle can weigh up to 12,500 pounds, a single axle up to 20,000 pounds, and a tandem axle up to 34,000 pounds. A tridem axle, however, has a maximum weight that depends on the axle spread.

A seasonal permit is another option, with a fee range of $300 to $600 and a validity duration of 6 months.
Here's a quick rundown of the permit types and their corresponding fees:
Signs, Flags, and Lights Standards

To ensure the safety of others on the road, signs, flags, and lights are required when moving oversize loads or superloads.
For night travel, amber marker lights are required on the front corners of the load. An additional amber light is needed on the leftmost portion of the load, which must be visible from both the front and sides.
Red lights are needed at the rear corners and must be visible from the rear and sides. This is crucial for visibility, especially in low-light conditions.
Los Angeles County requires amber lights at all protrusions and at five-foot intervals around the load. This adds an extra layer of safety, as it alerts other drivers to the load's presence.
The rear of the load should have red lights no higher than five feet from the ground. This ensures that the lights are visible to other drivers without being obstructed.
If the rear overhang exceeds four feet, it must have at least two lights or a rear light bar. This is an important consideration, as a large overhang can obscure the view of other drivers.
If the load obscures the signals and brake lights, a rear light bar is required during the daytime. This is a critical safety feature, as it helps prevent accidents caused by obscured lights.
