Automated Vehicle Testing in Vermont

This website describes the permitting process required to test an automated vehicle on state and town highways in Vermont.  It provides a link to the Vermont Automated Vehicle Testing Permit Guidance and Application and provides general information about automated vehicles. The Agency is currently seeking comments on the Draft Permit Guidance and Application, which was released in April 2020. There are currently no permit applications under consideration. Information about specific permit applications and testing will be provided on the site in the future.

Seeking Comments on Automated Vehicle Test Permit Guidance and Application

In an effort to hear from affected parties and the public, the Agency of Transportation is seeking comments on the Draft of the Automated Vehicle Testing Permit Guidance and Application. The Guide implements the AV Testing Act and describes the process and requirements to obtain a permit to test automated vehicles on state and town highways in Vermont. The Guide is intended for use by applicants who are seeking a permit to test automated vehicles on public roads in Vermont and municipalities that are considering allowing testing on town highways under their jurisdiction. It also serves as a guide to the Vermont Traffic Committee, whose approval is required for all automated vehicle test permits in the state, in its deliberations over specific permit applications.

Your comments are important to us.  Mail or email comments to:

Joe Segale, PE/PTP
Policy, Planning and Research Bureau Director
Vermont Agency of Transportation
219 North Main Street
Barre, VT 05641

The Agency is requesting comments by June 30, 2020. If requested, the comment period may be extended given the challenges of the COVID-19 pandemic and state of emergency.

On-Line Public Information Meeting. Friday June 19, 2020, 1:00-3:00 PM. The purpose of the meeting was to provide an overview of the Guidance and to take comments and answer questions. A video of the meeting is available here:

The Vermont Agency of Transportation will post responses to comments and a Final Draft of the Automated Vehicle Testing Permit Guidance and Application on this website. The Final Draft will be considered for adoption by the Vermont Traffic Committee during a public meeting. The date, time and location of the posting of the Final Draft and meeting have not been determined yet and will be announced on this website and by other means in accordance with the Vermont Open Meeting Law.

Overview of the Vermont Automated Vehicle Testing Act

Vermont’s Automated Vehicle Testing Act (“AV Testing Act”) became law in June 2019 (23 VSA Chapter 41) and creates a permitting process to allow the testing of automated vehicles, often referred to as self-driving cars, on state and town highways. A testing permit is required from the Traffic Committee, whose members are the Secretary of Transportation, Commissioner of Motor Vehicles, and Commissioner of Public Safety. The Traffic Committee is authorized to issue testing permits for the state highway system, class 1 town highways which are the continuation of US and state numbered routes through municipalities, and class 2, 3, and 4 town highways in municipalities that have pre-approved testing on their roads.

Automated Vehicles Overview:  Equipment, Systems and Why Test in Vermont.

Automated vehicles are equipped with an automated driving system (ADS) that enables them to operate with little to no human assistance, with the use of cameras, radar, lidar (image sensing), GPS, and computer vision to sense their surroundings. ADS can carry out the real-time dynamic driving tasks required to operate a vehicle in on-road traffic. There are five levels of automation, and a permit from the Vermont Traffic Committee is required to test vehicles on state and town highways with level 3, 4, or 5 automation (highly automated).

The Systems Behind Autonomous Vehicles

  • CAMERAS Provide a 360-degree view to detect traffic lights and road signs
  • LIDAR Laser scanner used to map surroundings in high definition
  • ARTICULATING RADARS Scan a wide field to monitor position of vehicles, pedestrians, objects
  • SHORT-RANGE RADAR Detects objects, pedestrians, vehicles near the car
  • LONG-RANGE-RADAR Measures speed of traffic down the road
  • VEHICLE LOCATION Information gathered from sensors plus GPS data determine the vehicle’s precise location
  • HIGH-SPEED PROCESSORS Crunch data from sensors to direct the cars movements.

Why Allow Testing on Vermont Roads?

Opinions vary about the time it will take for automated vehicles to be deployed and in use by the general public. One forecast suggests that vehicles with some level of automation will increase to 40-60% of all vehicles on the road by 2050[2]. A more assertive forecast suggests that 95% of passenger miles travelled will be in automated vehicles by 2030[3]. Vermont needs to prepare for automated vehicles, which have the potential to improve safety, increase mobility for people who cannot currently drive, and reduce travel costs for Vermont households, businesses, and visitors. Like computers and smart phones, automated vehicles will become increasingly important to our economic vitality. Testing in Vermont will help build public confidence that automated driving systems are feasible in our rural, cold, hilly state, and along our famous “dirt” roads. Testing will also provide an opportunity for law enforcement, emergency responders, road crews, engineers, transit operators, and other stakeholders to learn and gain experience with the technology.
