What are DOT Number Signs?

DOT numbers are unique IDs for commercial trucks and buses required and assigned by the FMSCA in the U.S. Department of Transportation. They’re mandatory for vehicles involved in interstate commerce, weighing over 10,000 pounds, carrying hazardous materials, or carrying a certain number of passengers. USDOT numbers must be displayed on both sides of the vehicle’s cab, with characters at least 2 inches high in a contrasting color, visible from 50 feet during daylight for safety and compliance.

By following these specific design and visibility requirements, companies ensure that their vehicles can be easily identified by law enforcement, other drivers, and the general public, helping to maintain road safety and regulatory compliance.

Types of DOT Number Signs

There are three main kinds of NY DOT number signs, different according to how they adhere to a vehicle. They each have strengths that make them ideal for different kinds of purposes and vehicles. They include:​

Vinyl Decals

Durable, weather-resistant, sharp print quality.

Magnetic Signs

Only sticks to steel; risk of theft or falling off.

Permanent and highly durable.
Labor-intensive, irreversible.

Before you order a temporary sign, make sure your state doesn’t require permanent NY DOT number signage. There are some that don’t allow magnetic or removable stickers to be used for DOT number signs. Also keep in mind that you will need at least two DOT signs, since it’s required in most places for one to be displayed on both sides of vehicles.​


Ordering DOT Number Signs has never been easier. Choose Signs New York for a seamless, customizable experience designed with your business in mind.

Why Are DOT Number Signs Important?

Safety Oversight and Monitoring

The DOT Number allows the Federal Motor Carrier Safety Administration (FMCSA) to monitor a company's safety record. This includes data on inspections, violations, and accidents.


The DOT Number serves as an identifier for each commercial entity, ensuring they can be held accountable for safety practices, compliance with regulations, and any potential violations.

Regulatory Compliance

Possession of a DOT Number signifies that a company is compliant with the requirements set by the U.S. Department of Transportation for interstate commerce. This ensures a standard level of reliability and safety among commercial transporters.

Public Safety

Ensuring commercial carriers maintain a certain level of safety protects not just the drivers of those vehicles but also the general public who shares the road with them.

Public Trust

Knowing that commercial carriers are regulated and monitored under the DOT system can provide the public with a greater sense of trust in the transportation industry's safety and reliability.

State Requirements

While the DOT Number is a federal requirement for interstate commerce, many states have adopted it as a requirement for intrastate commerce as well. Having a DOT Number thus helps in complying with state-specific transportation regulations.
