In Nebraska, you need a pilot car when transporting oversized or overweight loads that exceed specific legal limits. The state has established regulations to ensure the safety of both the load being transported and other road users. These regulations are in place to prevent accidents, damage to infrastructure, and any potential hazards that may arise from moving large or heavy loads.

The specific requirements for when a pilot car is needed in Nebraska are outlined in the state's statutes and regulations. According to Nebraska Revised Statute 60-6,197, a pilot car is required under the following circumstances:

1. Width: If the width of the load exceeds 14 feet, a pilot car is necessary. This ensures that other motorists are aware of the wider-than-normal load and can adjust their driving accordingly.

2. Height: When the height of the load exceeds 14 feet 6 inches, a pilot car is required. This helps prevent collisions with overhead structures such as bridges or power lines.

3. Length: If the length of the load exceeds 110 feet, including any overhang, a pilot car is needed. This ensures that other drivers are aware of the extended length and can maintain a safe distance.

4. Weight: In Nebraska, there are no specific weight limits that trigger the requirement for a pilot car. However, if an overweight load poses a risk to public safety or infrastructure, authorities may require a pilot car as an additional safety measure.

It's important to note that these requirements may vary depending on the specific route and local regulations. Before transporting an oversized or overweight load in Nebraska, it is essential to consult with the Nebraska Department of Transportation (NDOT) or local authorities to ensure compliance with all necessary regulations.

In addition to the above requirements, pilot cars must meet certain criteria set by the state. These criteria include displaying appropriate signage, having flashing lights, and being equipped with communication devices to maintain contact with the oversize load vehicle and other road users.

Overall, the use of pilot cars in Nebraska is aimed at ensuring the safe and efficient movement of oversized or overweight loads on public roads. By following these regulations, both transporters and other motorists can navigate the roads safely and minimize any potential risks associated with moving large or heavy loads.
