What Is a Trucking Safety Score and Why Should You Care?
A trucking safety score is a number that reflects how safe a driver or company is on the road. It’s based on various factors like inspections, violations, and crash history. This score helps insurance companies, regulators, and clients assess risk. The better your safety score, the more trustworthy you appear.

Understanding your trucking safety score is the first step to improving it. You want to be proactive, not reactive, when it comes to safety and insurance.

What Is an ISS Score in Trucking and How Does It Fit In?
You might be wondering, what is an iss score in trucking? The ISS, or Inspection Selection System score, is a specific type of safety score used by the Federal Motor Carrier Safety Administration (FMCSA). It helps determine which trucks and drivers should be inspected more closely.
The ISS score is calculated based on roadside inspections, violations found during those inspections, and crash data. The higher the ISS score, the more likely you are to be pulled over for inspection. This system helps regulators focus on high-risk carriers and drivers.
For you, the ISS score is a critical number. It influences your safety rating and can impact your insurance rates. A high ISS score means you might face more scrutiny and higher premiums. Keeping your ISS score low is essential for smooth operations and cost savings.
How Do I Find My ISS Score?
Finding your ISS score is easier than you might think. The FMCSA provides tools that allow you to check your safety data online. Here’s how you can do it:
Visit the FMCSA’s Safety Measurement System (SMS) website.
Enter your USDOT number or Motor Carrier number.
Review your safety data, including your ISS score.
You can also request a detailed report that breaks down your inspections, violations, and crash history. This information helps you identify areas where you need improvement.
Regularly checking your ISS score keeps you informed. It allows you to address issues before they become bigger problems. Plus, it shows insurance providers that you’re serious about safety.

How Does the ISS Score Affect Your Insurance?
Your ISS score plays a big role in how insurance companies view your risk. A low ISS score signals that you maintain good safety practices. This can lead to:

Maintaining your vehicles properly

Training drivers on safe practices
Addressing violations promptly
