Automated Speed Enforcement (ASE) systems are increasingly used in U.S. highway work zones to mitigate traffic risks, though regulations regarding their operation vary significantly by state. While some jurisdictions require the physical presence of construction workers for a citation to be valid, others, such as Maryland, permit automated ticketing regardless of worker presence.
How Automated Speed Enforcement Functions
ASE systems capture vehicle speeds and license plate data using radar or laser technology, triggering a camera when a vehicle exceeds the posted limit. These systems are designed to address the inherent dangers of work zones, characterized by narrow lanes, concrete barriers, and uneven road surfaces.

The legality of these systems depends on state-specific legislation. For example, New York state law requires clear signage warning drivers of photo-monitoring equipment and mandates that construction workers be present for enforcement to occur. Similarly, Washington state law stipulates that enforcement must occur only while workers are present, and requires advance notice signage for drivers.
Regional Variations in Enforcement Laws
State policies differ on the requirements for issuing citations. In Maryland, the law does not require workers to be present for an ASE system to issue a violation. Conversely, Florida currently restricts the use of ASE systems primarily to school zones and intersections rather than highway work zones, despite having stringent traffic safety laws.
California’s approach to work zone enforcement saw significant changes with the implementation of Assembly Bill 289. Under this law, citations are only valid if "photo enforced" signage is placed within 500 feet of the camera system, and construction workers must be present at the time of the violation.
Fines and Penalty Structures
Financial penalties for speeding in work zones vary by state and often follow a tiered structure based on the severity of the infraction.

- California: Fines start at $50 for exceeding the limit by 11 to 15 mph and can reach $500 for speeds of 100 mph or greater.
- New York: First-time violations carry a $50 fine. Repeat offenses within an 18-month period increase to $75 for a second violation and $100 for subsequent ones.
- Maryland: The state utilizes a tiered schedule starting at $60 for 12 to 15 mph over the limit, scaling up to $500 for speeds 40 mph or more over the limit. Notably, these fines double if construction workers are present in the zone.
- Washington: Beginning July 1, 2026, the state will implement a fine of $125 for a first-time infraction, with subsequent violations rising to $248.
Safety Requirements for New Drivers
States are also implementing preventative measures beyond automated enforcement. In Washington, as of May 1, applicants for a driver’s license who are under the age of 25 must complete an online safety course focusing on work zones and first responders before they are eligible for licensure.
These measures reflect a broader trend toward using technology to manage traffic flow and improve safety in construction areas. Drivers are encouraged to verify local traffic ordinances, as highway safety laws remain subject to legislative updates at the state level.
